I am looking to upgrade the stock brakes on my 2012 wrangler. The stock units are not up to the task. I'm looking for an upgrade. If I replace the rotors, should I consider new calipers or just upgrade the pads? Any thoughts are greatly appreciated! Running Pintlers & 35's.
Upgrade brakes

Don't forget the golden rule about brakes; If you can engage ABS, you don't need more brake....you need more grip. Brakes are not complex.....easiest path to better stopping is higher friction pads. I swapped to Hawk HPS when I upgraded to 35's.2014 Mercedes Benz E550 4Matic - Gloss White

There are lengthy ( I mean lengggggtttthhhyyyyyy) brake discussions on other, more general Jeep JK forums. I'd do some research there.
I have the Teraflex Big Brake kit on the front of my JK. And their master cylinder.08 Jeep Wrangler Unlimited Rubicon: lift, wheels/tires, bumpers, skids, sliders, winch, lights, cb. All the normal stuff, plus some.......

I have the hawk LTS on mine and love them. There is some brake dust but well worth it.____________________________________________

I upgraded my hemi JK to EBC rotors and pads and noticed a significant improvement in brake performance. And I did not go with the fancy slotted or drilled rotors. The main reason I went with EBC rotors is I needed new rotors anyway and I dislike buying the Chinese ones. EBC rotors are made in England.Comment

EBC has traditionally not been a good company; perhaps they've improved their quality since I wasted $1k of my money on their junk a decade ago (based on the shop's recommendation). Had to replace it all within six months (warped all four rotors and they only had a 90 day warranty).2014 Mercedes Benz E550 4Matic - Gloss White

Even the crappiest brakes I've ever driven with will lockup / engage ABS no problem at all. (i.e. my rust bucket 91 Subaru)
I've always thought the reason to go to bigger diameter rotors/bigger calipers is for more control, not more outright clamping force.
i.e. imagine one of those hand gripper things for exercising. Imagine the hardest one you can just jam shut with all of your might, and hold it there. You don't have a lot of control, like you can't open it a few millimeters and hold it there, then close it again and do that repeatedly for half an hour. It's too much effort for you to have that level of control and endurance.
Now Arnie comes along (bigger calipers/rotors). He can still jam it shut just like you, but he has the extra power to be able to have extremely fine control over opening/closing it for basically as long as he wants without fatiguing. That's the benefit of the bigger calipers & rotors, you have so much more control and input before the brakes lockup, rather than just clamp on/off.
----
I've always been surprised you can't get calipers and rotors from some other Chrysler/Jeep/Dodge/RAM to bolt up.
Surely someone has found something that works.

I swapped my brakes (mopar code BRW) with the BR6 (Heave Duty ones):
68044865AA ADAPTER, DISC BRAKE CALIPER $27,99 x2
68049018AA PIN KIT, DISC BRAKE $6,99 x2
68044862AA CALIPER ASSEMBLY RIGHT $70,99 x1
68044863AA CALIPER ASSEMBLY LEFT $70,99 x1
68044866AA (new) 68044866AC PAD KIT FRONT $152,99 x1
68040177AA 13" ROTOR FRONT BRAKE $85,99 x2
68045998AB Master Cylinder new# 68091278AB $101.99 x1
68045999AB BOOSTER, Power Brake $121.99 x1
The only problem is that you have to order the parts and wait 2-3 weeks for delivery (or at least I haven't found anyone with these parts in stock).
PS: The Booster & Master Cylinder are the BR6 parts from the 2011+ JK models ;-)
The whole thing is plug and play, and you do see an immediate improvement. Btw these are single but huge piston calipers and the rotors are of a 13" diammeter and weigh a mere 11 kilos each !!!
I tried the old brake pads on and they seem to fit (photo above), but I preferred to keep the new ones on. I also installed a set of Gorillas
Next mod is swapping the brake lines with a set of these ..

Don't get me wrong...I've had upgraded factory brakes and/or Brembo's on most of my cars in the last decade whether or not they were equipped that way from the factory. I'd like an OEM option for the JK just because; that said, pads alone alleviated my concern about diminished performance from 35" tires.2014 Mercedes Benz E550 4Matic - Gloss White

I think from 11+ the brakes are indeed improved, but there are at least three brake codes (instead of the two BRW & BR6). Depending on the model, there are the normal BRW, the heavy duty BR6 and one for the models with start-stop engines. So I guess you should do a little research first to see if you need to upgrade or not.

there are also differences for USDM vs the Euro market. I believe AEV has said their upgraded brake kit is from Euro market parts so we may not have access to those here. It would be nice to have someone with Mopar parts experience to give us USDM guys a verified list of what's needed. The tools aren't there for me to do it like I could do for BMW's or MINI's (i.e. www.realoem.com)2014 Mercedes Benz E550 4Matic - Gloss White

Anyway, I was just looking at the 2011 parts manual (page 66/67 of 673) and the rotor/caliper etc part #s are the same. I guess you have the small ones but you can still upgrade to the 13" disks. And yes, you can find these parts in the US (that's where I got mine from) but you need to order them.Last edited by kacos; 06-04-2013, 02:07 PM.

so, 07+ is the same down low but 11+ has upgraded BB and MC, leaving the "upgrade" path to ALL THE ABOVE for '07-'10 or EVERYTHING BUT BB and MC for 11+? Did I follow that logic correctly?
