So ive replaced both rotors and calipers
still did the stuttering, bumping, shaking- only when braking
seems less when cool or colder, worse for sure when very hot
started to flush the brake system, (wife ran out of patience) seemed to help for a while, back to brake shake.
A friend just bought a 96 that seems to be doing the same
whats causing this- is it common among 4runners in this series?
Before I start the FSM testing I thought Id ask
searched for a bit didnt really see what I was looking for

Thanks!

Do you mean warped brake rotors? Yes, that's a fairly common problem. Here's a recent thread here about a possible fix:

but ive replaced both rotors and calipers with no change

not an upgrade, just new parts for the stock 16's

so why does it still, shimmy, vibrate, bump, shudder...

Hard to say without being there and checking a few things.

I would check upper and lower control arm bushings, ball joints, tie rod ends, and wheel bearings.
