[DeTomaso] STOCK Brake Calipers rebuild

[JDeRyke at aol.com]

Good luck, Barry. Know that most rebuilds only clean up crud and replace 
the square o-ring, and maybe the dust boot for each bore (available from some 
vendors as a kit). But some leaks come not from a bad o-ring but from 
pitting of the pistons that may also tear o-rings. For reasons that escape me, all 
Euro calipers thru at least 1990 use chrome or nickel-plated mild steel 
caliper pistons. This includes all Girlings, Cobra and most Porsche calipers. 
And like old bumpers, plated steel will rust if water is present- which it is 
in most brake systems. The only fix for this is replacing the pitted 
piston.
