'04 Cavalier. Considerable pulsing in the pedal when the brakes are applied. The pulsing is speed-dependent - I think it's probably one throb per wheel revolution. There's no significant shaking of the steering wheel. Stopping seems unimpaired. There may be some variability in the pulsing: it may be worse after coming off a short run at higher speed. (That is not certain, though.)
What I've done so far:
- Changed the (front) pads. Outer pads had more wear. Calipers now moves freely.
- Replaced one rotor. Inside plating was deteriorated.
- Replaced one hub assembly. (see (1) below.)
- Replaced the other hub assembly last fall, to fix a noise.
Things I can do next:
- replace the other rotor. My gut says, this won't help. Sometimes, my gut is wrong.
- look at the rear (drum) brakes. The rears on this car are mostly cosmetic, IMO. Not to mention, Getting the drums off is a PITA.
- get the balance checked on the wheels.
Or something else?
Any thoughts/experience appreciated.
G(1) re hub assembly replacement: When I ran the car (low gear) with one control arm jacked up, wheel removed, lug nuts snug on the rotor, wobble was visible in the rotor. It was pushing against the brake pads, and I thought for sure this was the problem. No joy.
