I have had reasonable success removing moderate amounts of oil from
seal leakage from rear brake shoes with CRC Brakleen. The surface
needs to be saturated several times and then wiped off very quickly
until no material is evident on the wiping surface. It may take ten
or more applications and a roll of paper towels, but when done I saw
no noticeable deterioration of the liner surface. This may not be
true of all liner material and I wouldn't try it if the surfaces are
really soaked with oil. Do this outside, the fumes are ghastly.
