Oil soaked brake discs-cleaning

plowhand · Aug 7, 2019

My brake discs have a lot of meat on em yet but they got oil soaked due to bad seals is there a good way to get em to grab good again?

If they are riveted linings, cook em with a torch. If glued, they will likely fall apart from the heat.

Heat with a propane torch (outside). use a roundy round approach to not burn the facing, but heat the oil out. It may catch fire, but don't let it burn. Let them smoke. Do both sides. When cool, try brake clean on them to drive any residual oil out. This is a time consuming process, and really about the only way. It does a 90% job, but seems to be usable when reinstalled. Remember the whole stack of parts must be less than .o60 on a sm or larger, and .045 on smaller tractors. Measured from the housing to the inner disk when face up on the bench using a straight edge across the housing. If more, the housing needs to be machined down to that spec. New disks (i do not know the thickness off hand) might be a solution if yours are thin (they look fat when they are actually too skinny to work correctly. They never get to the point like disk brakes on a car, or shoes on a drum brake. Jim

I've scrubbed then in clean solvent, brake cleaned them, then steamed cleaned them and left them out side in the weather a few days. Then ruff them up with 80 grit sandpaper and put a random finish on the expanders with a DA sander.

What are they on?

If a tractor, they might clean up as others have suggested.

But if this is an on the road vehicle, not worth taking the chance. Replace them!

Back in 68-69 the garage did the heat on the car and actually let the fluid burn up. I hasver donr the same since with Deere tractor brakes.

Bury them in a bucket of Oil Dry for about a week. CM
