Hello everyone,,
1992 Celica with about 130k miles.

The brake pedal pulsates at a rate directly proportional to how fast the car is going. How violent the pulsing is depends on how hard you apply the pedal but even at less than 5mph and even when barely applying the brake you can feel it in the pedal.

I’ve had this before on other vehicles and the fix was swapping rotors. Rotors are cheap enough for it so I changed the front and then the rear with no real change from either swap. As part of the swap I wire brushed the face of the hubs to make sure there wasn’t rust buildup on them. Replaced a wheel bearing on the passenger front as it had some play in it. Swapped tie rod ends as they had some play. Bled brakes enough to refresh the fluid.

The changes have made it drive a little better (at least I like to think they did) but the pedal is almost completely unchanged.

I think that to feel it in the pedal it has to be an irregularity in the rotor or something else causing the piston in the caliper to move.

I’d sure appreciate any help/tips folks might have as to what to look at.
