I have some information on the braking system of the BU Renegade, there are two different front brake setups. Logically we can assume the larger is for BU Trailhawk...

Front Brakes: 11 x 1 in vented rotors with 2.24" single piston floating calipers
Trailhawk: 12 x 1.1 in vented rotors with 2.36" single piston floating calipers

Non Trailhawk Renegades will have a 116 square inch swept area per caliper
BU Trailhawks will have a 139 square inch swept area per caliper

Rear Brakes: 10.95 x 0.47 solid rotors with 1.5" single piston floating calipers
Trailhawk: 10.95 x 0.47 solid rotors with 1.5" single piston floating calipers

Rear calipers on both Trailhawk and non Trailhawk BU Renegades will have a swept area per caliper of 102 square inches.

Both the Trailhawk and Non Trailhawk Renegades make use of vacuum assist, standard ABS and an electric motor mounted on the caliper for the parking brake.

Anybody know for sure which disc size goes with which model?

Obviously, we can assume that the TH gets the larger 12" disc due both to its off-road capability and larger engine size. We can also probably assume that the 2WD base version probably gets the 11" disc.

However, do we know if the larger 12" disc is possibly also used for ALL 4WD versions or what disc size applies where?
