I have a problem that the brakes are sticking ! When I shut down the engine the sticking is gone. It has to do with the vacuum somehow I think.
I have a 1977 P6 3500 with dual system.
I made a drowing how it is assembled. It is just alittle bit differenty than I saw in the Haynes manual:
Let m,e explain this amateur drawing:
high Left corner is the master brakecilinder. Ther are two pipes leaving the master cilinder.
Number 1 from the front of the plastic reactionvalve. This hose divides into two hoses which are connectet each to metal tubes positioned under the engine and ending at the front outer tubes from the servo unit.
number 2 from the mastercilinder (just before the reactionvalve ) directly to a t-piece which iut connect it to the inlet manifold and with the tubes going to the back of the servo unit.
I hope this makes sense....
The difference with the 1974 setup is that my servo has two entriws for the hoses oming from the reactionvalve.
Second the hoses from the back of the servounit are bothe connected to the vacuum from the manifold and dirctly to the mastercilinder via the t-piece.
the 1974 drawing shows that the two hoses from the back of the servo unit are sperate and not connected via a t-piece. one hose to the master cilinder and the other to the manifold.
Could the way my vacuum hoses are attached be wrong? Or might there be a leak some where causing my brakes to stick?
thanks in advance for your answers!!
