[DeTomaso] Wilwood Brakes WTF????

No, I have disassembled both master cylinders and calipers down to bare
castings and there are no valves.

It could be that only the American cars have the valves in the master
cylinders.  

Maybe Europeans have them in the calipers or distribution block?

They have to be somewhere in the brake system or else you have a delay
in the brakes being applied as the pistons would have a much longer area
to traverse before they contact the rotor.

	Must be an American thing. Euro master cylinders I've come
across have no valves built into them.

	Disc brakes require 2 psi residual pressure valves.Drum brakes
have 10 psi. valves.
	Most master cylinders have them under the flare seat  where the
brake lines are screwed in thats why you do not normally see them or
think about them.
	Without the residual pressure the pistons retract much further
in the caliper and there is a delay while the piston has to travel
further before it contacts the rotor.Not good as seconds count in
braking distance!
	Mike's valves are "add ons" because his master cylinder does not
have any valves built in.His valve pressure is correct as the pads did
not drag on the rotors before the pad wear/cocked pad happened.
	Just what i have learned from playing with lots of cars  :  )
