I've read the messages about brake shimmy but none seem to apply to my situation; thus this post.
I started noticing shimmy when braking over 50mph a few months ago. My car had apx. 30,000 miles at the time. There was no shimmy until I touched the brakes and then it was pronounced. As soon as I drop below 50, there was none. Not just less: none. Then it would seem to go away completely at any speed. Now, at 36,000 miles, it's back. VERY back! I took the car in because I thought this might be due to rotor warp. The garage said that my front rotors were within 1 degree run out but one of my rear was at 2. (the max, they said) So I had the rear rotors turned and pads replaced. $300.00 later the problem is still there and they still say the front rotors are fine. I'm finding that brake parts for my Mazda are unrealistically high so before I sink any more money into them I wanted to ask if anyone has any ideas on this? The inconsistancy of the problem and speed/heat thing has me baffled.
