Thread: Brake troubles

Looks like crud on the calipers-are these old used units??? does the spraque even work?

Are you doing anything with the Ford parts?

and did you bench bleed the master cylinder??

If this was my system I would check each caliper to see that the piston wasn't stuck-would move easily with a little compressed air into the line-----I would bench bleed master----I would get a stock OEM type combo valve---------2 lines from combo vale to front calipers and a 1/4 line to rear housing where splits to 3/16 to each side caliper

What I don't understand is just how are you turning the discs???? running the engine in gear??
Make sure the combo valve is centered----when OEM started using them it was to prevent lost of front and rear brakes with a failure in one half of system-------this seems as though the valve isn't centered in the system shutting off flow to the rear, but I don't like the CPP valve so don't have any idea on it----it seems according to the description that it is basicly just a junction for the brake lines and has a brake lite pressure switch built in--in other words-doesn't have function of the OEM type combo valve which delays front brakes while rears are engaged and then porportion fluid pressure flow to the rears to prevent lockup and allow the fronts to be primary braking.
