Aftermarket brakes

Just got my new lift on and brakes are feeling a little sluggish. About to throw on 33's so want to make sure I'm nice and safe on the highway. But going with 35's around summer time so I want something campable of stoping them no prob also. Just looking for some setups to look into and about how much I'm looking to spend.

A very large number of Jeepers swear by EBC yellow pads and Centric rotors (no holes, or grooves)

go on ebay and find brakelabs or r1 concepts. i have used their brakes several times before with great results each time. i used their drilled/slotted rotors and ceramic pads. much improved braking, better wet braking and no dusting on the wheels. they're typically around $200 for all 4 corners pads/shoes and rotors. i plan on using them again when my JK needs new brakes.

Don't waste the money on drilled or slotted rotors.

Vanco if you are looking at 35's

Several of the above posts are right on. Avoid drilled/slotted/dimpled rotors, they won't help for the type of braking a Wrangler does.

The Big Brake Kit from Vanco at powerbrakes hydroboosts vacuum boosters everything for your extreme braking needs is the ultimate brake kit that will restore the braking with 35" tires back to what it was like with the small factory tires. It replaces the wimpy single-piston OE calipers with bigger dual-piston calipers in a stronger housing that resists flexing which keeps 100% of the brake pad surface on the rotor. Under heavy braking, the OE single piston caliper housing flexes and can't keep all of the pad on the rotor which reduces braking performance. A power brake booster is not needed for this kit. It's not cheap at about $800 but it's worth it. My last TJ that was stolen had this kit, I hope to someday get another for my replacement TJ.

Shy of that, the next best braking solution is to go with EBC Yellow Stuff brake pads and a high quality smooth rotor like from Centric. EBC Yellow Stuff pads are about the only pad out there that will produce a truly dramatic and highly noticeable improvement in braking performance. They're not cheap but they work very well. I have installed them onto friend's Jeeps and all made dramatic braking improvements.

For 35" tires, I would not waste my $$$ on any other pads. I know the developer of the Vanco kit (mrblaine... Blaine Johnson) and he has tried literally all of the various brake pads that fit the housings we use and only the EBC Yellows were dramatically better.

I always go for a Master Power brake booster, bolt in application and no power steering lines to deal with like you have with a hydroboost.

That will work for most other vehicles but it won't for the TJ.

The problem is the TJ's weak caliper frame and its wimpy single-piston design. The factory OE power brake booster already puts out more pressure than the caliper frame can withstand without flexing which reduces the brake pad swept surface area. Further increasing that pressure with a bigger/more powerful brake booster just makes the problem worse. That weak frame is the true cause of the TJ's poor braking with bigger tires... the power brake booster is putting out more pressure than the caliper frame can withstand during heavy braking which causes it to distort/flex out of position. Even the pads flex when pushed hard by just one piston, dual pistons spread the force over a larger area of the pads which keeps them flat on the rotors.

That is what Vanco's solution fixes... it provides a much stronger caliper frame together with a dual-piston brake caliper. The stronger Vanco frame doesn't flex so the OE brake booster's pressure can be fully utilized.

It took a long time to finally get to the root of the problem, that weak caliper frame and single piston caliper. Together, they were unable to withstand the OE brake booster's full pressure before flexing and being able to apply all the pressure to the brake pads (which also flex when under a single piston) the OE brake booster is capable of.

Hmmmm news to me...put on on pop's rubi and never looked back. But I did check out the vanco site and they show the same kit for 90+, so that would lead me to believe the caliper bracket on the YJ's and TJ's are the same?

That's a question for Van at Vanco, I don't know jack about YJ brakes.

LOL, I just thought it was interesting that a booster won't work on a TJ, but they do on YJ's just fine...and yet they appear to have the same braking system

A booster DOES reduce braking pedal effort, which leads most to believe it helps the braking. But for big tires, it just makes it easier to overpower the brake caliper frame and brake pads. For overall braking, it doesn't improve braking performance for big tires... it just takes less brake pedal effort which only helps for normal braking needs. If you are trying to stop big tires on a TJ, maybe a YJ too, a booster just makes it easier to overpower the brakes.

All I'm saying is that it works well on the ones I have put on regardless of the theory.
