I have an 85 930 that has recently (i think) developed a brake problem. When I press hard on the brakes I get a bad vibration in the steering wheel.

The faster you are going when you step on the brake the worse the vibration.

The harder you press on the brake the worse the vibration.

Brake pedal feel if firm and catches almost immediately with very little travel.

This may sound crazy but I would swear that I was not having this problem before I hit a peice of retread on the interstate. After that I noticed this problem right away.

Thanks,
Kirk
