Someday I would like to install bigger rotors. I recently switch to Black Magic pads and Centric rots. The difference is significant though the rotor is about the same size. It's all in the pads. I can stop a lot quicker with my 35s than I could with a stock setup. I imagine these pads with bigger rotors would be incredible.

We do have a big rotor kit that gives you a larger rotor and a bracket to reuse your stock caliper.
The 4303480 and 4303490 kits are now available for sale. These kits include:
• Two front caliper brackets that space the factory calipers farther away from the unit bearing, allowing space for a larger rotor to be run
• a pair of plain big rotors (4303480), or a pair of slotted rotors (4303490)

The vehicle must be equipped with 17” or larger wheels for the kit to fit.

But those are just front rotors, right TeraFlex? Why no rear rotors? I know on bikes the front is more important and usually bigger but is there no benefit in using larger rear rotors. My wheels are 17" in size. Not sure if the slotted rotors make any difference or if they wear the pads fatser.

over 60% of the braking is done by the front brakes. While one could up grade the rears you just wouldn't see the same results as you do on the front. The time this changes if you are towing a lot of equipment, hence why 3/4 on trucks come with large rear brakes.

Any benefit to slotted rotors? I just order some expensive stuff from you guys today but the rotors may be my next upgrade for even better stopping power.

The slotted rotors are there to help evacuate the gasses that are generated when braking so that the pad can maintain better contact, and they are sexy.

So I just received my big brake kit from teraflex today as well as the crown lines (set of 4)... What I don't understand is how do u know which of the lines are front and which are rear? I didn't see any indicators... Did I miss something? Could they be all the same length? (I didn't lay them out side by side yet).
Standing by :-) - am starting the install 9 am

Not sure how the crown lines are but our lines look identical other than length. We have 26" long ones for the front and 30" for the rear. Hope this helps some.

Thx Teraflex.. so the longer ones in the rear...
Now can you confirm a 2012 Rubicon does NOT need a new master cylinder and your kit is ok to run with OEM one?

also, trying to put locktight on the caliper bolts I was loosening them to expose more thread when the caliper dropped off... fell from about a foot (wheel height)... hit the ground on it back (ie bleeder side).. bleeder left a nice mark on the cement floor... bleeder cap has a whole in it.... no other signs (ie cracks) visible.. should I be concerned or is this thing strong enough? any symptoms to look for?

It should be fine. inspect the bleeder for any cracks and when you fill it just look for leaks. If the valve is damaged you should be able to snag one at the local napa.

Smadja from the info we have it seems like the 2012 needs the MC. It seems like in 2013 Jeep put a larger MC on the wrangler, but I spoke to someone with a 2013 the other day and they needed the new larger MC so I don't think the info we got from Jeep is quite accurate.

hm... well completed the install...
what issues should I be looking for regarding the MC?
what symptom would tell me the OEM is insufficient?
