Another awesome show! Thank you all again for the FREE schooling.

[@ShockTherapyllc]

Thank you.

[@curiousgeorge684]

oK everything is awesome, love the show including the F100. Makes me miss my 53

[@DonkeyEvo]

AP racing was working on a pretty nice brake kit. Nicest aftermarket caliper setup I've seen.

[@TheBeatenTrail]

Awesome video, always very educational!

[@rick3446]

I’m looking for better rotors for my 64” x3 what rotors was Justin talking about that you run. Thanks Guys awesome products and videos 👍

[@zaneturner8423]

I was told by some professional Kart racers that the drilled and slotted rotors are for gas relief. When the brakes are applied the pads contact the rotors and a gas is generated between the rotor and the pad.

[@KuschallRacing]

you are getting better and better ! very importand customer informations....first suspension and brakes before horspower, drivability is faster and saver !!! well done, keep going....expand your busines ! maybe offer the brake-driveline tooo....! i would buy it for my x3 64....

[@ShockTherapyllc]

Thank you

[@rosyskyler185]

I didn't know that the higher the boiling point the more susceptible it us to absorb water i just assumed there were no down sides to running a higher dot fluid but of course there is good bit of info I always wondered why cars wouldn't just come with a Dot 5-6 maybe I should have started by figuring out what DOT stands for hmm

[@KTMcaptain]

I read a paper back in college published by Chevy on slotted vs drilled rotors. It's conclusion was the drilled rotors work better for allowing gasses to expand, but slotted rotors don't crack nearly as easily as drilled.

[@ShockTherapyllc]

Very cool. Thank you for sharing.

[@rosyskyler185]

In a car I left foot brake and roll on the throttle a little with the brake still on i use the mix of the two to modulate especially in a slippery situation i use the throttle to keep the wheels spinning when hitting the brakes and not lock up the wheels so I keep the throttle open a little just to keep from locking up and modulation but thats front wheel drive car not a cvt sxs with a belt

[@TK2HOTSHOT]

Does anyone know what flexible line was used at pivot points?

[@PinMonkey1960]

Interesting brake segment. Explains my lack of stopping power. 👍🏼. Random thought when i watched speed utv i saw no clutch cover. Then when the ending walk around of Justins it had no cover. Just for sand? What is the reasoning. Btw i trail ride Upper Michigan mostly.

[@ShockTherapyllc]

We had the cover off just to put a new belt on it for testing. That’s all. We always run the. Cover.

[@KTMcaptain]

What about a large inboard brake on the rear locked differential to reduce unsprung weight? Even go with brakes on the front diff's outputs... . The buell brakes, and project orbis awd civic type r brakes for that matter, have the caliper mounted on the inside of the rotor so the rotor can take the wider diameter of the caliper's previous position. Pretty cool.

[@ShockTherapyllc]

Due to skid plate clearance the rotors could only be 6-7” in diameter so braking force would be less than half of stock.

[@KTMcaptain]

@@ShockTherapyllc hmm... well, it seems like someone needs to come out with a new differential housing. . Two ring gears offset and laid down horizontally, so parallel with the horizon, driven by two pinions from one shaft that bisects the gap between the two ring gears, one drives the front of one ring gear and the other the rear, and the axle shaft outputs are driven by pinions off the dual ring gears and can be angled down to improve CV angle. The top ring gear will have an output that is similar to a standard diff output but is on top of the diff case because the ring gears are horizontally laid down. That output will drive a brake rotor as large as you want. . BTW, this is a very similar setup, without the remote differential, to a TATRA suspension diff swing axle unit. Except Tatra has the ring gears perpendicular to the ground and attach outputs to the ring gear directly. . I believe this could create a differential that is stronger and provide extra clearance. . kzbin.info/www/bejne/ZmTXhZdqe6aEfa8

[@randytremaine1622]

When converting to hard lines, what/who is a good source for the custom flexible lines that will be required, thanks a bunch !

[@ShockTherapyllc]

Actually any local high pressure line company will do. For us that is the Parker store or Hose power. You can also get them in any length you would need from Summit or Jegs.

[@chadshumaker2789]

Got any suggestions for some better brake fluid for racing? I boiled mine in my last short course race and didnt have any brakes for 3 laps. I think I would like to start with the 1200 degree stuff and see if it holds up.

[@ShockTherapyllc]

Castrol or Motul 5.1 brake fluid. Great success when we have used them.

[@XerexBueno]

FYI - tooltopia.com has those jacks in stock.

[@justindemott4990]

What paint marker do you use or what are you using to mark the bolts for movement?

[@ShockTherapyllc]

Cross check

[@justindemott4990]

@@ShockTherapyllc Thank you!

[@mikekenyon3322]

master cylinder size is a critical component

[@markmanning6773]

Brass pads are for slow mud and creek riding. Fast riding will melt them.

[@ItsSimplyToGood]

What are your opinions on the 64" vs the 72" X3 Turbo RR?

[@ShockTherapyllc]

72 all the way. better everything including shocks.

[@ItsSimplyToGood]

@@ShockTherapyllc 72 it is. Thanks for the fast response 🤙

[@JDHarpr]

So you have any experience with the Ebc solid steel Utv rotors?

[@ShockTherapyllc]

Yes we run them on our race cars. Work great

[@JDHarpr]

Just to specify, I am referring to utvx6380 for example. It Has no holes or slots. It only has the v cuts at the top. Is that the same as you have experience with?

[@ShockTherapyllc]

@@JDHarpr no. Ours have through holes

[@JDHarpr]

Thanks for the response. I was wondering if the solid no holes would warp. Ebc says they shouldn’t. What do you guys think? Fast trail riding, heavy on the brake a lot etc.

[@ShockTherapyllc]

@@JDHarpr you should be fine. We have never warped ours even with them nice n blue and boiling the brake fluid.

[@miller440x]

Brass pads are for mudders, they dont grab as hard but last very long

[@joshparsons2534]

Brass pads are only for riding slow in mud. They outlast other pads but dont grip and stop for shit.

[@sxsnorthtexas153]

The Honda Talon has factory hard lines...

[@ShockTherapyllc]

And that is one of the things I love about that car

[@zlothra]

1st?

[@DUNEATV]

YXZ has an E-brake. Because it has a real ⚙️ transmission! 😘

[@s.p.i.racing7509]

Yxz also has the worst suspension so😂😘

[@DUNEATV]

@@s.p.i.racing7509 Compared to what my off road friend?

[@s.p.i.racing7509]

@@DUNEATV an X3 my guy. I know they make kits that change the mounting location, creating better geometry. But stock not a chance

[@DUNEATV]

@@s.p.i.racing7509 My Dad has an X3 XRC 72 inch. We primarily ride Glamis dunes and Arizona Desert. I am well aware that it has better suspension and more power but that’s where the advantages end!

[@KTMcaptain]

What does a parking brake have to do with the transmission? Hoonigan x3 has a rally style e-brake...

[@CapeCodCNC]

You might be a little high on your boiling points....
