Rotors warped again, 4th time

[boatpuller]

The rear brakes working unevenly should be an easy problem to correct, most of the time it is just that the rear brakes are out of adjustment, the automatic adjusters don't work that great, before I put disc brakes on the rear of mine i had to manually adjust the rears at every oil change so that the rear brakes could pull their load.



Hope that's all it is,

Does your truck have the 3" rear brakes? I had similar problems with death wobble (turned rotors 3 times, 3---4 thousand mile intervals) until I upgraded to the 3" brakes and larger cylinders. I now keep the rears adjusted and have had no more problems, about 25,000 since last rotor turn.

I have a '91 W-250 that had a serious front-end wobble similar to a tire being very seriously out of round. Accelerating from a stoplight, when you hit 25 mph the front-end would start shaking violently, to the point of loss of control of the direction in which the truck was going. It would move into other lanes. You could either floor-it and drive out of the vibration or hit the brakes. Had the tires rebalanced and rotated many times. Still had the same problem. It turned out to be that the inside hole where the bearings go was machined off center. Put new rotors on and solved the problem. Boy, were those rotors expensive, though. I think I might have gotten screwed but, the shop that did the work were able to figure out what was wrong when others couldn't. Hope this helps. Joe.
