I'm dealing with a 1994 Toyota 4Runner with the 3.slow engine and about
190k miles on the chassis.Lately and increasingly, there is a *lot* of vibration when braking from over 40mph or so. I believe that this comes from the front end because I tried applying just the parking brake at speed. In that test, it stopped smoothly.
I lifted the front end and did a good old fashioned wiggle test, but found nothing noticeably loose. I also lightly applied the brakes while rotating each wheel by hand. The grab seemed smooth, but I'm not real sure if this would be a good test for a warped rotor.
What, in your collective, esteemed opinion would be the likely causes for a rather violent shaking of the front end when braking? BTW - the brake pads are still in good shape, although I didn't measure them, but there is plenty of meat left.
