Recently had a left fork seal leak, appears the seal saver/film technique worked and the leak has stopped. Unfortunately I think the left brake pads may have been contaminated (haven't disassembled yet). Question is, is there any way to DE-contaminate/clean the pads? Also, if I end up replacing them, is it better to replace both sets so they wear evenly? They appear to have some service left on them. Thanks for any advice!
