My brakes are locking up while driving in traffic! I just put an Ls2 and T56 tranny and was wondering about the extra weight could be causing this. It made a 363 mile trip on the highway with no problem. In town it seems as if the brakes get hot! The right front tire actually locked up. I took it to the car wash to cool it off and I made it home. I also have long tube headers and I thought the brake lines could be getting hot from the headers. Everything seems to be hidden pretty well and away from the headers. I am at a loss, Has anybody had this problem before?
