rear brake caliper

[schnowz]

I always use brake fluid as a solvent with either a brass bristle brush or 
toothbrush. As Bill said getting the crap out of the seal groves is the 
hardest and dental toothpicks are good. I'd do that part first as it is the 
most likley section to be beyond repair. It's a bitch to clean up the rest 
to find the grooves are beyond repair.
