my brakes dont really have much stopping power. i have stock r32 gtst type m brakes. whenever i step on the brakes it makes sortof a grinding and clicking noise. the pedal feels really stiff when i push on it. the rotors look fine, no ridges. the brake pads seem to be fine, but they might be for a different car, because i found a brakepads box for a Y32gloria in the glove compartment. also one of the tension rod bushings is torn, will this affect my braking? i just recently bought the car. any advice on this would be greatly appreciated.
