Carnage - Deleting The Brake Booster On Our V8 Lexcen

The brake booster has been all kinds of trouble on our V8 Lexcen project so we decided to delete it altogether with this master cylinder kit from Castlemaine Rod Shop.

At least you put out more episodes than the binky lot! Thanks Scotty!

[@DaveHiggoHiggins]

"Begin slowly using full strokes, then a combination of short and long strokes" Scotty.... a missed opportunity. I'm not mad, just disappointed.

[@STREETMACHINETV]

I know right. When I reviewed the video I was like "OMG! how did I miss that!"

[@young11984]

Always seems like i make the most perfect flares while the nut is laying on the bench laughing at me😂

Truth

[@John-ok6sq]

Anyone who has ever made a brake line has done that at least once.

[@sugarb6613]

You really are a jack of all trades, Scotty. I can’t be the only one that watches your videos and thinks how much I’d love to drop my project off to you to take care of all the frustrating little jobs.

[@thepieguy4522]

Remote booster wouldve been a smarter choice financially

[@castekracing]

I love watching these build vids. Doing some amazing work mate, jealous of your skills and knowledge

[@davidc2902]

Look into changing the pivot point on the pedal so you fix the pedal ratio which will improve the pedal feel greatly. Non boosted pedal ratio should be closer to 6:1 where as boosted pedals can be about 3:1

[@dazaspc]

Indeed The pedal should also be higher with more travel to give the same swept volume of fluid capability. The reason is if you ever loose a line or have a hose leak you can still get some braking even though the pedal is very low. The idea is enough fluid flow in a single push to give 50% of the volume of the plumbing to the caliper plus the full working volume of the caliper cylinders. If you don't you should have an automatic cut off valve in the system to prevent completely draining all the fluid before the brakes stop working. These are often integral with the master cylinder but sometimes not. The ratio does need to be increased but usually 4.5~5.5 to 1 is enough as the pedal can get quite high.

[@someyoungguy6990]

Can we get a big CHEERS MATE for Matt! For keeping Scotty safe from the tangled mess of zip ties and reworked wiring we all love to hate oh so much. The young fella needs at least a two drink a week raise!! Hey, who else was waiting for the dad joke after the chat on "pumping it up with a combo of short then short and long strokes".....?

Mate it's always the small jobs that take the longest. I had to fit some new gauges to my boat the other day. Even a standard replacement Yamaha Speedo gauge wouldn't fit due to the pressure sensor hitting the mounting bracket. So then the bracket has to be modified. This build is coming along great. I see your Instagram & comment on the posts. It's looking schmick now.

[@steveb9270]

Hay, did you have a look around for a remote booster? I had the same problem years ago, and found a booster that could be mounted anywhere. Worked a treat to .

[@anomamos9095]

Tip. Brakes are often made by one or two companies for all the vehicles made in the country. This means that parts of a Ford will often fit a gm or Chrysler. So if something doesn’t fit your mod look at what’s available from other brands.

[@zeropaloobatheuber1572]

I’ve got an AU Falcon reservoir on my commodore master cylinder 😉👍 Needed it cos I’ve got a VX master cylinder on my VS.

[@The_Performance_Laboratory]

I was almost expecting the engine to not fit again at the end... Hope you're finally past this hurdle.

[@STREETMACHINETV]

It all fits now. Looks great too with the pipework and everything

[@peterschmidtchen8560]

Hey Scotty, have ya had a look at Hydro boost? It runs off ya power steering pump and replaces the brake booster. I'm researching them for my Impala that has a lumpy cam.

[@STREETMACHINETV]

I hadn't heard of them until recently but will look into them for future builds

[@davidwindsor4632]

O another brakect. 😂 Binkiy I think is sitting idle. 😮 Good to your breaks sorted. 👍

[@gregivey183]

Hey Scotty Check out StealthSS in Warrawong NSW..in car under dash booster kit (ford)/pedal box... Good luck on the build,mate

[@golfr600]

Rod shop need to change the blown Torana sticker to the Ferrari engine now lol

[@young11984]

Simple solution to the harder brake pedal, put some brake pads thats more aggressive in grip then it takes up for the lack of a booster. I use hawk hps for small light cars and dtc60 for heavier vehicles

[@sipposbft]

I did tell you this 1st up no?? Yr welcome Scotty 🤣

[@michaelb5330]

Scotty got to ask why not a remote booster? Cheers

[@Bozza_1]

A possible intake manifold solution for you is a really nice looking sheet metal manifold made by a company called Clumatetune. I’ve seen them make good power on some 1UZ powered drift cars.

[@michkolm1537]

Remote mount booster under dash fits ezy next to string colum

[@LV-FOURTWENTYSIX]

Is it possible to do a remote booster setup if need be? She is coming along well. I dont have a project at the moment so living my car mod jollies through this channel 👍

[@STREETMACHINETV]

If it doesn't stop we'll look at remote booster options, but right now I just want the car up and running

[@phredflypogger4425]

Great job but could you not have used an inline booster?

[@wesgates5632]

Great kit, be nice if they had one with a line lock.

[@paulreynolds1510]

Would there be any space for a remote servo now you’ve gone to the survey delete kit?

[@PaddyBoy644]

Great job on the detail work Scotty, this things going to be awesome! Cheers Pat

[@steveknopka7673]

You could make it vacuum assured by installing a VH440 remote booster like the old Holdens and valiants had. Is an easy fit!

[@STREETMACHINETV]

Easy fit where? there's no space with turbo and piping

[@jonathancarson6032]

Hay mate if the manual brakes are not great marks 4x4 do a hydrolic assist break booster that run off your power steering pump if your running power steering.

[@brushitoff503]

Love it Scotty! By chance @08:36 did you happen to install those block of bolts on the wrong side?

[@STREETMACHINETV]

Umm, no, because the hardware for the proportioning valve only works one way

[@351tgv]

Lucky that this Lexcen did not have ABS. Also aas others have mentioned most likely a PBR booster from a Falcon would of worked especially from EB onwards as Ford had the same issues when they re-inserted the Mustang 5.0L HO V8 and had to convert it from LHD to RHD. of course not 100% sure but I do know that Ford had those issues at that time.

[@jonling5173]

I’ve done a booster delete kit in my torana , the pedal is surprisingly good thought it would be rock hard but apparently it’s all to do with the bore size of the master

[@STREETMACHINETV]

Good to know

[@rustinpeacegarage]

Scotty not sure if it what you were after i think that prop valve bracket is for lhd mine mount on the on the other side (gaurd side) just letting you know there is an option

[@STREETMACHINETV]

Yeah, I know about that but it clears the engine (just) and the lines are all done now, so I'll stick with this

Great stuff, just wondering why you did not use a hydro booster?

[@STREETMACHINETV]

Because I hadn't even heard of them before last week

[@outandaboutinoz]

@@STREETMACHINETV new to me as well, they are a great option for improving the brakes on a 70 series landcruiser. You go from 1000 psi to 2000psi, so you have to run braided lines as well. Cheers.

[@dazaspc]

Just a heads up you know you can get hand held double flaring tools and they are a bit more work but are only $80 or so. Much easier in compact spaces.

[@STREETMACHINETV]

Never had much success with them, but I must admit that usually I've tried the cheap ones

[@dazaspc]

[@plumbs7199]

Awesome skills mate . On another note , being a Gasfitter, I can’t help noticing the open ended natural gas ball valve. Just being turned off and not being plugged . Might want to get a licensed pro to make that safe ? Not really legal atm. FYI anyway! 👍

[@STREETMACHINETV]

Thanks for the info

[@ChristopherHallett]

It's probably disconnected at the gas meter on the building exterior.

[@nathanielbarbeau4821]

Question: If the coil packs did not fit then why not go with LS coil packs remotely mounted and use spark plug wires?

[@STREETMACHINETV]

Good question, I just think they would be untidy. I want this engine bay to look its absolute best.

[@nathanielbarbeau4821]

@@STREETMACHINETV okay I figured it was an appearance thing. Like you said though…you grew up on manual brakes, so you know what to expect. I never did, so I would’ve tried to keep the brake booster. That WILWOOD sure looks good though!

[@tony66au]

Non boosted brakes are fine :-) You just have to allow for more reaction time with 4 wheel jam tins (Drum brakes) and make sure proportioning and adjustment is good, Disc/drum combo's can be tricky but again if the system is looked after they are fiiiine. The Willwood with the proportioning valve especially near the 1 inch bore will be a nice pedal with a bit of adjustment, Used one on a VG Sedan with a disc conversion and once dialled in with softed Disc pads she was better than a good OE boosted setup even chucking her around the Mt Dandy tourist road back in the day.

[@Low760]

Which was fine before ADR rules on minimum stopping distances. Dr Tim did some good articles explaining this stuff a few years ago in Australian street rodder. Pedal effort has to match a certain amount of force out with the booster and master cylinder. Going to a smalller bore size (vs was 1.25" by then?) Should compensate.

[@Beer_Dad1975]

I remember my first experience with un-assisted brakes - a 1975 Triumph Spitfire - scared the hell out of me as I pushed harder and harder and still nothing seemed to be happening...

[@tony66au]

@@Low760 Disc/drum combo with solid fronts and 7/8th bore and the proportioning setup worked quiet well, I did re-line the entire car both hard and soft lines which made a big difference and applied that knowledge to a mates VB Commodore later on and both carss tested better than OE on the decelerometer. Worth mentioning that the Willwood master also has a slightly longer stroke and all in all was a great modern package considering I bought it all from the Summit catalogue (Before Online was a thing :-) The Val was quiet a light car too so front rear bias took some fiddling for wet weather but as id gone right through the entire system inc slave cyls on the drums etc it produced fantastic results. :-)
