I have always had weak brakes, have made many of the recommended
changes with only little improvements.
Measured the Brake fluid pressures and found:
Front drivers: 800 psi
Rear drivers: 750 psi
The Master Cylinder is a Raybestos MC39075 and the Combo valve is new.
These pressures seem low to me, especially the front.
Is there anyone out there with info on what these pressures should be
and/or what is causing the low pressures??
TIA
