disc brakes soaked with oil?? help
I just bought a mtn bike with bb7 disc brakes. The previous owner soaked the rotors with oil, with hopes of preventing rust.......Obviously now the pads are corrupted. Is there any way to revive them? Anything that should be done to the rotor past a clean with rubbing alcohol?
thanks in advance
thanks in advance

If there was just a bit of oil I would say to sand the pads. However, given that you say soaked, I'm pretty sure you're going to have to replace the pads.

The sure-fire way to fix this is to purchase new pads and rotors. Failing that...
Buff the rotor and pads with an abrasive (my favorite at my shop is a piece of skateboard grip tape). Scrub the rotor and pads with dish soap and hot water, Dawn with NO additives (scents or lotions). Then take a torch to both the pads and the rotor, careful with the rotor you can warp it and screw up the temper. Only just barely touch the flame to the rotor, just enough so you burn off any reside. The pads, if they are sintered metal, can take a cherry red heat.
Buff again on a clean sheet of abrasive, then reinstall.
IF you don't feel comfortable doing this, just buy a new set of rotors and pads.

spray and wipe the rotor with brake parts cleaner, then spray one more time and let it air dry.
