I have a really bad brakes on my FC. I have to stand on the brake pedal and it still feels that the car wonīt stop quickly as it should. Could it be master sylinder or slave sylinder? How can I check do they work ok? What else could cause this?
I changed rotors and pads 2 years ago. EBC rotors and red stuff pads. I know these are kevlar pads and they need to warm up to get them work effectively but thatīs not the cause.

Thanks

 

check your brake lines, they could be expanding too much, or you could have air in your lines.

 

Also dheck your booster, and the vac lines (with check valve) that connect it to the LIM on the other side of the engine...
