Brakes

[OSCAR II]

It was a great price, think it was around $600 ... about half of what Q-tech wanted.
The calipers are just stock painted ones, nothing special. But was ready for brakes and here's a whole setup.

I went digging through brake packages from jeep a couple years ago and I'm pretty sure there are 5 different pakages 4 for the 4dr and 2 for the 2dr with the one shared. That was when the 392 just came out.

If I bought a 392 JL, I'd have the Delta Brakes waiting for it at home and install them before I left the house with the 392.

In the end, it just does not matter given the performance improvements, and I have no plans to go and measure the surface area of the Teraflex versus OEM in an attempt to validate either stance.

If 9% is the number that you like...go with it.

Sorry, my brain goes severely OCD when people post details like that.

Yeah, those brakes look impressive. I wish they weren't quite as significant of a hit to the budget, but oh well.

I'm sure teraflex are great but at around 4x the cost, that's tough to swallow. I've never been a fan of drilled and slotted rotors for a jeep. Less surface and more areas for sand and rocks to get stuck imo. I haven't checked but does black magic make pads for the jl? I had them on my tj and they were decent. As far as locking up your brakes, I'm not sure you'll get that with abs. I do wth my tj with no abs.

4x the cost of what though? Powerstop? You cannot use that as a baseline given the fact they are no better than OEM.

You can lock up your brakes with ABS with the Teraflex--you will never do that with OEM--the clamping power is just not there.

Teraflex delta . The best...
Powerstop calipers are only manufactured factory calipers
I called powerstop and ask what was special about there calipers. I was told they are factory calipers with factory rebuild kits and painted
Don't do what a lot of use have done and waste your money and time on inferior brake system
Do it one. Teraflex delta brakes

I'm still having trouble when you use the term "locking up" your anti lock brakes since they don't really "lock" up. But whatever.

Yeah, 4x the cost of just doing OEM equivalent pads and rotors. I know teraflex kit replaces calipers as well. I get it. The mopar hd kit with everything can be had for under 900. Teraflex may very well be better, I take your word for it. But i haven't had the need for anything better than the brakes that came on my rubicon with 35s and I've made some quick stops where you can feel the anti lock brakes doing their thing (I assume what you call locking up) as they repeatedly lock and release leaving very short broken skid patterns.

Maybe I would feel the need if i had 37s or larger. I just can't personally justify the 4x expense when it comes time to replace my pads and rotors.

The Mopar kit is the same as what comes on a Rubicon if memory serves and so it is nothing special. Mine do not pulse like ABS that I have had in other vehicles--they never have and I can make the tires squeal when braking on pavement with 37's and a Jeep that weighs 5700# empty. Whether or not that means there is an issue with the ABS on my Jeep not sure, but when I say lock up, I mean the wheels stop turning and the tires slide--Teraflex has a YT video showing the difference in braking power.

I could never do that with the stock 33's and brakes--they would push right through the pads and as I upgraded from 33's to 35's to 37's and added skids plates, winches, etc. it only got worse.

Teraflex is better because there are 4 pistons on each wheel clamping Toyota Tundra style pads on the rotors. The OEM brakes will never be able to come close to that because they do not have pistons on both sides of the rotor and worse yet, the caliper metal is so thin they simply flex and you lose much of whatever clamping power that you had to begin with.

For those who do not have added weight or larger tires and do not have a need to make an emergency stop, the OEMs may work for them--they never did for me off the lot.

One other thing with powerstop. I think they only offer one kit that is a replacement for package #2. It might work as a replacement for package #1 but I'm not 100% on that.

Sounds nice!

yeah the abs shouldn't allow you to do a real solid skid. But I'm assuming you don't have an abs error light.

Question, I read a lot of folks got soft pedal after the install, until they use a scanner to do the "abs bleed". Was that your experience?

 

[Willys41]

Any buddy that doesn't believe what we are saying about Teraflex compared to other less expensive systems . Go ahead and buy what ever you want
Been there done that
Baer SR4 / powerstop Z36
I now have Teraflex delta brakes and I am done Puts a smile on my face every time I put my foot on the brake pedal AND
One reason Teraflex work so well is because of the anti knockback springs and the Toyota Tundra brake pads

So really, everyone should test a panic stop and see if they get ABS activation and pulsing indicating the threshold of traction is reached. If not, upgrade brakes. The only problem I have is I don't think Teraflex fits stock wheels.

No ABS light and it was checked by the dealer shortly after I bought it.

My pedal was soft from the factory and only after I did the ABS bleed when I installed the Teraflex did I get a high and solid pedal.

The initial bleed is enough to get you started, but you will not have a 100% firm pedal until you do the ABS bleed. The valves have to actuate to allow the air to pass through the system.

Agree on the panic stop--I would be surprised if any Rubicon (stock or not) can lock up the tires. I think many people would be shocked at what a panic stop feels like...

For the stock wheels, I feel confident this is correct due to the size of the calipers. I have 4.750" backspace or 0 offset Icon Alphas and there is only about 1/4" clearance on the backside of the front wheels.

The OEMs are +44 offset and I doubt they would clear.

First you and roaniecowpony excite me about the brakes, then crush my hopes . I guess it's Hawk LTS pads one day for me.
