[@AussieArvos]

Have you guys felt the need to upgrade your brakes on your 4wd?

[@offshoreoffroad]

I have a 1991 80 aswell this upgrade is definitely on my list now after watching this. Very informative!

[@k2svpete]

Absolutely. Like you said, they're often overlooked but may save your life or that of others.

[@MicahBell_1860]

Should be one of the first considerations

[@35manning]

Not yet. My '89 GQ can still lock the wheels, so plenty of braking power and being a manual with 4.2 diesel, I almost never need to use my brakes on decents (assuming I grab the right gear) and in fact more often need to use a little bit of accelerator. When they are due, I will be considering larger rotators, braided lines etc. Another thing you didn't mention about braided lines, is the bulging of the lines when braking. Braided lines give less, thus give a firmer feeling under braking which is why most race cars like using them.

[@MicahBell_1860]

He did mention "swelling" instead of bulging@@35manning Same shit, different smell

[@garyg2128]

When are we going to see Liam's car?.....I've been waiting for weeks and weeks..

[@AussieArvos]

We will have an episode next week 🤙

[@Typingwithpaws]

great video! I remember upgrading the brakes on my '85 L300 4x4 to 1995 pajero brake assemblies and a custom rear disk conversion. very similar results to what you've experienced!

[@OffTheBeatenPathAus]

Great video as always guys, safety can be boring and is often overlooked in favour of more fun mods. That's a tangible improvement for sure.

[@Philipk65]

Good to see you guys back. Great idea to upgrade the brakes on your vehicle, really aids in stopping. At 4:46 I really don't think the poor mullet would be to pleased to be tapping the cap lol 😂

[@HammerRocks]

Brilliantly presented and another informative episode. No doubt about your creative and editing skills. I mean, these are TV level quality segments. But not only that, they;re easy to follow and easy to understand. 👏👍 Such a cheeky thumbnail 😁

[@AussieArvos]

Thanks you Hammer!! that means alot mate! HAHAH i know right, cheers :)

[@damiansilvester9928]

Bloody good job mate, well done! Like your enthusiasm, open & honest demeanour and having a good crack without Bullshit!! Like you I keep my vehicle & camping gear reasonably simple versus some other 4WD shows with all the bells & whistles, complications and massive weights their hauling around. My early BT50 just racked up 252,000 clicks of reliable trekking in pretty much most environments around OZ including working as a driving instructor, engineering work at mining & resource sites etc. Next time your in East Gippsland, would be thrilled to hook up.

[@TerryBeatson]

Awesome vid as always Patty, I feel like the 80 doesn't get as much love from the fanbase these days because of Liam's GQ makeover, but it's awesome to see the odd little updates. The 80's really turning into a proper touring rig, and that's coming from a Patrol guy!

[@ratedxxxable]

It's a MALLET, not a MULLET. 🤣😂🤣😂 4.47 mark of video.

[@k2svpete]

I mean, you could use a mullet. Just need to hose off the blood and guts afterwards.

[@Chook57]

They should make a huge difference mate..

[@michaelsimpson9779]

A bit of gentle carressing with a 40 grit flap wheel and a cardboard cereal box shim for clearance testing and you can run 15 inch rims on the rear of the 80 series. The fronts clear the 15s untouched. Don't ask me how I know...

[@unluckyalf2007]

Nice vid. So good to see that you took an alternative route the usual Bendix option

[@dugsbugs1]

The most overlooked component is the proportioning valve. Over the years, I have changed everything with little result. It wasn't until I put a new proportioning valve on that I actually got good brakes. Now it pulls up like a supercar.

[@2ndGearLow]

Great video Pat, I was just watching this while having lunch and was pleasantly surprised by the shoutout! Glad we could help and keep up the awesome content 👌

[@AussieArvos]

No worries!! Absolutely live by your tutorials! Cheers :)

[@Jeep.wj.tj.australia]

Another great episode 👍🏻

[@cyclemoto8744]

Well done. Having upgraded the booster on my 76 after much delay due to the cost. I realised I should have done it sooner: the money was worth the additional safety

[@brandongoberdhan6335]

Very cool upgrade

[@quinshaechanpaseuth4454]

your old man sure can craft anything mint vid

[@Bush-Tv]

Great video Pat, Luckily for me I'm running the bigger size on the 95 80 Series I do want to upgrade the rotors very soon. Plus I noticed one of the bearing races is a little loose inside the hub, So now looking at changing that over as well. Keep up the good work Lads. Almost at 100K 👍

[@AussieArvos]

Thanks bush TV! Lucky you haha! Cheers mate! Getting there!

[@ash300186]

Another great video Pat! I was looking forward to seeing you remove the cone washers because i reckon you would be one of the few that do it correctly 😅

[@craigtomkinson2837]

Lovely Ep, My 1HZ - 1990 - 80 series on 265/75 x 16s has great brakes, and has a good hand brake Id never change, In fact the engineer who did my GVM upgrade said there better than a lot new 4wds out there,

[@AussieArvos]

Thanks Craig!

[@mick457]

brakes have always been my second mod, right after full exhaust, did it on my falcon and my paj

[@krishilkaba3339]

This video made my sunda🎉 Thanks ausie arvos ❤ From Tanzania.

[@AussieArvos]

Thanks so much krish, means alot!! 🙏

[@Aiden-nl5ti]

Any time I pick up a spanner I'm excited if it's a mod or a general peace of maintenance. Enjoy the process of working on your car ( mechanic by trade so even after 5 days of working on cars I still love when the weekend comes and I can work on my rig)

[@ashleyduvall1962]

I’m pretty sure you can tune up the rear end a bit so it splits the brake load more evenly and saves the front locking up so quickly when you stomp your foot on the brakes. Anyway, neat video. 👍🏽

[@WaydeFn]

finally another vid ive been waiting weeks ahaha

[@jescowan26]

great to see this important info coming out, safety will keep you and your 4X4 safer and on the roader longer :D did you swap the rears for the fronts? when rotating tires?

[@allanpower8041]

Well presenred Patrick, good job!

[@AussieArvos]

Thanks Allan!

[@keilfestin4606]

Great video mate definitely need a good break upgrade especially while loaded up and over 3T 4wd

[@AussieArvos]

100%! Cheers :)

[@tonygreen8221]

Great video mate. I reckon you should have given the hand brake shoes a good buff up with the wire brush.

[@Eye_Candy_Promotions_Australia]

Well done, another great vid 👍

[@AussieArvos]

Thanks mate!

[@HendriMouton]

Great vid man. Might be worth mentioning the brakes are only as good as the grip you have available. I did a brake upgrade on my 97" FT spec (which already has the bigger brakes) with some performance brake bits, huge difference in instant stopping power and long decents! Even with the ABS on the 80 (which is very rudimetary), I had to pull the fuse for most road conditions. It actually causes a major increase in the stopping distance on gravel. The only benefit with keeping it would be the advantage of having steering while you run off the gravel or into some game haha

[@johnnoblemedia]

Great video boys.

[@AussieArvos]

Thanks John!

[@froggy0162]

Those tests showed just how good ABS is!!

[@clintonmorris1945]

Great video once again, but watch you light bar. That's a defect waiting to happen. You can now get flush mounting ones that on the top bar.

[@michaelsimpson9779]

That second braking test at 11 mins, the roads wet... sure to lock up more easily.

[@gapnfap9223]

Very good vid on your part Pat. Love how you made your own template to cater for the rears instead of going to toyota. As for the brakes.. haven't heard of them but on the market for a brake upgrade for my 04 td42ti ute. P.s was this a sponsored vid from the brake manufacturer or just an upgrade you've had your eyes on?

[@MinnieMaus-fl8bk]

Same model, same modification and i am still Happy. Regards from Germany.

[@Shaanjc96]

Just fine the same with my 105 series! Worth checking your brake portion valve if the 80’s came with them? Mine was seized

[@tonykrause9652]

Just a thought if you’ve done a two inch lift,did you readjust your load sensing and proportioning bypass valve,as the valve is set to factory height,this could be putting to much into the front end brakes making them lock up .

[@Stevenk770]

Have you changed the Brake Load Proportioning Valve? Mine started to leak and I since changed it and I felt it helped with the stoppping

[@charliedelacour5545]

good grippy mud tires also help, I suspect with razars you won't even lock up

[@matthewhubbard7177]

I have a 91 HDJ 81 with the very small rear rotors. The rotors are very expensive to replace and I'm considering upgrading. Not sure if the backing plate will need to be replaced.

[@murrayblair2159]

Is fitting the bigger disc not require the 16inch rim? Ive often read guy's wanting to fit 15inch rima to the later year models

[@RingoTravels]

Another great video 😊

[@AussieArvos]

Thanks Ringo!

[@tadeuszmichaelwlodarczyk3120]

Nice up grade✔️✔️. I pump my brakes like abs no problem

[@stco2426]

Great vid.

[@AussieArvos]

Thanks mate! 🤙

[@bentheguru4986]

LOL @ Special bearing pre-load tool. Get yourself a brass drfit punch and read-up on pre-loading.

[@legsofsteel1]

Nah. Just get the 3 times finer bearing adjuster. Made in Adelaide. Look them up.

[@bradrees92]

Love the channel and your work boys, cracker of an episode. I've gotta say though this convinced me to stick with my stock brakes. If you're looking to shorten the braking distance, any possibility of locking up Is going against the gain. Rather put both feet into it than thinking about having ro regulate brake pedal pressure when avoiding an accident.

[@AussieArvos]

Thabjs Brad! yeah makes you think!, wouldn't be an issue if you had ABS but i definitily can't just slam it to the floor like i used too, have to be more controlled. i have noticed since making this that the bigger rotors have been better for more repetitive braking e.g long hills, as the caliper stays cooler.

[@sbiggs10]

great video i am wondering did u mention that u should bleed the brake as well

[@dylb2858]

Hit with a mullet 😂😂

[@user-uq5ge3pd4j]

So going camping in the Grampians at the end of July wondering the best place to do that any ideas would be appreciated thank you

[@CustomcrowdMitroc]

cant beat a bigger booster aswell. having drilled rotors will prevent fade caused by gases being built up from the break pads when they heat up

[@guitarplayerlp7018]

great job but no anti rattle springs on the front?

[@bencook5166]

Unfortunately braided brake lines are a really bad idea on a 4wd that does remote travel! The reason being……….you can’t clamp them like you can a rubber hose. So if there’s ever an issue off road you can’t just clamp a hose to ensure you still have brake pressure to the other brakes.

[@camlawson2725]

Hey mate, I've blown a braided line and my vice grips clamped it off easy as. Dunno where everyone gets this from

[@fatmanoverlanding]

Another brilliantly done video. Superb editing and presentation. I agree with you 100% brakes are critical and often overlooked. Ive got a 1996 LC80 and already w/the bigger brakes, but they too I found lacking, so I've upgraded to the Heavy Duty dba rotors and Bendix pads. Though I'm yet to upgrade to braided lines. I"ll do them along with when I upgrade my brake booster. Great episode. 👍

[@AussieArvos]

Thanks Fatman! Means alot mate! Yeah makes a big difference driving know you can pull the car up a few metres quicker! Cheers

[@sammyjones3500]

My toyota cruiser got so bad breaking it can't be driven. I bought those larger calipers for the front. Really appreciate your help AussieArvos.

[@AussieArvos]

No worries mate! Cheers

[@FlemoJosh]

You should also consider upgrading the master cylinder to suit the new bigger calipers and just because the age of the old one as-well

[@AussieArvos]

Agreed, I forgot to mention this, I hadn't done alot of research on them, but agreed next thing to do for the braking system! Cheers

[@andrewphillips8966]

Still keen for gum boys was late today 😅was out the the kids on the mx track

[@LockyourHubs4WDing]

I did this on a mate's early Sahara 80, it actually stops now! Check out bearing adjustment nuts from Trail Gear in the states, much better setup than the two locking nuts and lock washer.

[@AussieArvos]

Thanks mate! Yeah it makes a big diffrence!! thanks for that info, that looks really interesting, might have to try them out! Cheers :)

[@MicahBell_1860]

My 93 GXL does have ABS. First question, does the 100 Series have bigger calipers to fit the bigger pads, & do they fit the 80 series. Secondly, I thought this video was going to be about installing a dual diaphragm brake booster. But you didn't?

[@officialWWM]

Whenever I hit the brakes on my old XJ, I cross my fingers and hope for the best. Tiny front discs and dodgy rear drums…it’s not exactly confidence inspiring!

[@TastyAzWhole]

You should mention that the brake rotors comes with oil so you must use brake cleaner on it to get rid of it first before installing

[@fachu2]

Be careful with Protex 4WD pads, I put a set in my GU and they were great around town but out on the trails and on steep descents they would fade massively. I changed them out immediately after that. (I don't normally say anything negative about products but this is super critical and it needs to be said.)

[@stefanwitt4184]

the stock proportioning valve wouldnt be set up for the larger front rotor, adjusting it might get you an even better braming distance

[@Ben-nt7fx]

how much would it cost to do everything

[@dijm8]

well done on making flat spots on your tyres....on next weeks episode we got new tyres fitted! 🤣🤣

[@AussieArvos]

😂😂 I know right

[@hisheroship]

I have an 92 LandCruiser, and I can’t believe how small the brake rotors are. Landcruisers don’t like to stop accelerate or corner.

[@brianmaclennan561]

Bleed the brakes?

[@dustyfarmer]

Smart move keeping the brake rotor backing plates. They are a safety item that increases braking when you need it most, IE: When you use your brakes. Try some of the DBA XP pads, I reckon they are great for stopping power & lifespan.

[@AussieArvos]

Thanks dusty!

[@matthewlindsay4701]

She’ll be an off-road beast once you get the lockers in

[@deanasser8813]

Hey patty, loving you're channel! Can i ask where did you find your factory service manual online? And what were the part numbers for the new backing plates? Ive just done big brake upgrade on my 80 and bent them to clear. keep in mind you can also fit an bigger brake booster which will require less pedal effort and make braking more predictable! With your rear axle seals be sure you push them in past the little leading edge. Otherwise, they like to walk out and fill your bearings with oil.

[@AussieArvos]

Thanks Dean! Part numbers in the description! And if you google Toyota 80 factory service manual you should find it! 🤙 Thanks for the info! Cheers

[@AussieArvos]

Oh and yes and I think upgrading the brake booster could be a good one too!! Just didn't get around to it this time!

[@BenMitro]

Nice upgrade. Just a question, is it viable to retrofit ABS on the 80 series?

[@AussieArvos]

I think the later models that abs, I know the 105 series did

[@davidcase4041]

Hi guys love your channel. You mentioned you use Partsouq, which I have come across. I have 1995 GQ, which partsouq do supply parts for. The issue I have, it doesn’t recognise my VIN. (LHD Philippines model). Do you know or does anyone know where is the best place to find parts numbers. Cheers Dave

[@AussieArvos]

Hi Dave! I just google to be honest, I usually can find them in a forum post or something!

[@jamespugh3729]

If your fr9nt brakes are l9cking before the rears then your LSPV needs adjusting. Your rears should always lock first, just before the fronts.

[@ravensnax]

throwing it out there did you adjust the proportioning value might help the brakes locking up? Also the dual diaphragm booster from pdi will also help reduce braking distance again, but its still a great video keep up the good work

[@AussieArvos]

Thanks raven! I forgot to mention about the brake booster, it is something I'm looking at but ran out of time !

[@Stevenk770]

Don’t the 80 series already come with a dual diaphragm booster?

[@user-on4vw8zp2q]

you should also rust proof under the 4wd

[@TURBOTRISTO]

Should have thrown some nitro axles in it while you were going man! Perfect video

[@ericjohnson6802]

And upgrade the cap screws as they shear off too easily.

[@AussieArvos]

Hahaha should of 😉 thanks Tristan!

[@FlatBrokeAdventures]

I put new larger rotors on my 4by and it made a huge improvement even without touching the rear

[@AussieArvos]

Yeah just looking through the footage you can see how much force is going through those front brakes!

[@FlatBrokeAdventures]

@@AussieArvos Yeah true. I put larger tyres on and it reduced acceleration and increased braking distance and feel so I did the upgrade

[@legsofsteel1]

Were you already running 16inch wheels? I would not have thought those brakes would fit in 15 inch wheels.

[@FlatBrokeAdventures]

@@legsofsteel1 yes I have factory 16 inch rims

[@mj_aussie_coaster_travels8310]

Doesn’t matter how good your brakes are if your tyres can’t grip the tarmac, something off-road tyres are shit at.

[@ShayneMostyn]

Thats a better thumbnail lads.

[@Falcon_Overland]

Ooops, I litterally just upgraded mine last week and went straight to 130kmh and slammed the brakes on to see how much better they were and proceeded to do the same another 3 times 😢

[@nilz6432]

how to kill pads and warp rotors 101...might get lucky, but if you find anything suspicious switch pads. Also most manufacturera have stopped advising the bedding in procedure given here. Anyway recommendation is 100-200 km light braking (exept emergencys) and as an option the bedding in as shown here, however it usually is not necessary anymore with modern pad materials. Always check what the pad manufacturer recommends.

[@jayarre1839]

hydrobooster is the best thing i ever did to by gq wagon.

[@jarrod1687]

Same with gu, best brake mod you could do, doubles your line pressure. No need for bigger tb48 calipers and rotors

[@__beer__]

I just took my 'new' 91 model 80 up to big desert over the long weekend, was great but the brakes are rubbish!

[@AussieArvos]

Yeah especially when you begin to load them up!

[@outlawdingo3020]

You definitely don’t want your tires skidding as that can be a loss of traction thus you slide further and you aren’t able to steer if you need to

[@yukaira]

just a heads up your temperature readings probably aren't accurate, you cant measure heat visually on shiny things like brakes!

[@Nethlon]

105 pads have a little more surface area, they're not thicker.

[@nolz262]

So I assume you’re not running 15s?

[@AussieArvos]

16" rims, and with the new rotors in a very close fit, no chance with 15"

[@nolz262]

Spewing I’m running 15s 😅

[@worthy_escapes]

"Next we adjust the handbrake" We all know Toyota handbrakes are non-existent 😅

[@Norskenxtreme]

My 4x4 is a RN46. It will not stop in any kind of emergency lol

[@scooterbmx_world8433]

Bruuh u forgot the drum brakes in the back of the car

[@jonolikesHiluxes]

my dad has 2 2.4L Hiluxes that crashed on the same hill because they couldn’t stop :(

[@ConscientiousObserver]

Seems like a lot of work for a small upgrade. Why not get them from a 70 or something else from this century

[@froggy0162]

The main thing to remember is that if you’re going to driving a big heavy 4WD around you wont be able to stop like a proper car - because physics. 4WD tyres have relatively poor grip, the dynamics are poor and the weight is a lot of kinetic energy to lose. So drive slower and conservatively on public roads and try not to kill anyone - im looking at you lifted ranger drivers!

[@matty_isthemotto]

I got a 4wd so i dont have to stop 😂

[@Herbal69]

Moose? I've smashed a few roos but never a moose.

[@SUPERTRUCKER166]

The downside to braided lines is if you damage them out 4wding etc (yes a stick or branch can still puncture them) you won’t be able to crimp them off. And it’s not a race car so the effective benefit of braided lines is zero.

[@jayarre1839]

load of shit, braided lines lessen fade because they’re not rubber

[@k2svpete]

You don't need a race car to benefit from braided lines. The main improvement over standard rubber lines is the reduced expansion of the line under braking, giving more feel and allowing greater hydraulic force to be applied to the pistons, rather than lost to expansion in the lines.

[@ashmelville4421]

I like watching u guys but you have a hoist why are u still sitting on the floor?

[@brandongould6555]

And because the road is wet

[@bradgray123]

You need to learn Modulation Braking.
