Just did whole brake system, Hawk hps, Brembo blanks, rebuilt caliper in front. Out back brembo drum, new shoes, cylinder, springs. Also did Goodridge stainless lines. This is on a 91 civic si. When going over about 30 and lightly pushing pedal I get vibrating. Do you think rotors are warped (didnt check runout due to being new rotors) or do stainless lines need a break in or something? Help me please!!!
