Warped300

I've been having the same vibration problem with GS300 brakes since I've owned my '94 (bought it in '00 with only 49K on it). It's most annoying. I don't even drive it hard, so there's no real reason to have ANY brake problems in a car like this. Am now preparing to replace the front rotors again, after probably 60,000 mi. Anyway, I've owned four MR2s in the 14 years before getting this car, and I NEVER had warping problems in any of those fun cars. And I drove them hard, as they were an absolute blast to drive. Am now going to try cross-drilled and slotted rotors, as I'm guessing that it's a cooling problem that is warping them. The only "hard" driving I do with them is coming down off-ramps at a relatively high rate, but I'm still babying the car otherwise. Have read elsewhere that sitting with brakes applied at a light after such braking can keep too much heat on that portion of the rotor while stopped; sounds good enough to me after all these hassles!

I've had similar problems and they seem to stem from the emergency brake cable. Apparently, they tend to fray over the years and that causes binding. Once you apply the emerg brake, it remains on even after releasing. Very frustrating and very annoying. It's a shoe-type system inside the hub of the rear drum, so they just continue to drag and wear out. Mine are shot and require replacement, so I've had to do without the emerg brake for months now. Not good. Had the same problem with the hood release cable which I HAD to replace, as the hood would pop open (to the safety latch point) when going over severe bumps. Since installing a new cable, no problems at all. Hope this helps.
