I have replaced my front calipers and pads and still experiancing at shake while breaking between 65mph and 45mph.. No shake above or below those speeds. I took it to a shop for a brake inspection they said everything was ok.

I am at a loss. I have tire cupping on both front tires really excessive cupping wear on the driver side compared to the passanger side.

Please I am at wits ends I cant take the shaking anymore its shaking the patience right out of me.


Spec on the car are

2001 Mercury Sable
24v DOHC motor

any thoughts or suggestions?

New calipers and pads, but you did not mention rotors. Were the rotors replaced? Warped rotors will do this.

You need to have the alignment checked for the wear issue.

uggg im slow..

I meant to type rotors and pads not calipers.

Alignment was done when I got the two front tires on about 4 months ago.

Did this start right after alignment & tires? Did your old tires have the cupping problem too? I would question the accuracy of the alignment especially if the tires are only 4 months old.

There may also be loose ball joint, tie rod ends, or other issues making it shake when braking. If it shakes bad with new rotors and pads (assuming new parts are good) then you have a serious problem.

Something sounds really loose and it may not be safe to drive until it's looked at. I had a Tempo that shook when braking and I replaced the rotors and it still shook. I racked it back up and wiggled the wheels and found an extremely loose tie rod! It was ready to come apart and could have caused an accident.

Please have the car checked out at a reputable shop.
