Pull the master off the booster, start the car and see if the pedal moves freely. If it doesn't the booster is bad.

Residual bad?

Have been pondering this situation over and over and am wondering if the residual is bad? If I pound the brakes hard and the rears do not lock up, is it the residual valves fault? If there were no residuals in the system and no proportioning valve either then wouldn't the fronts brake last and the fronts first. I tried a hard brake situation and the rears did not lock up! Been researching all info. on this and there are so many conflicting reports. Some say you don't need residuals if the MC is on the firewall, but do when the MC is lowest. Others say the contrary. Some say you don't need a proportioning valve when running residuals, others say you do. Still others say don't use an adjustable proportioning valve, use a stock GM. Do you need residuals if you have just a proportioning valve, be it adjustable or non-adjustable? Where is the middle of the line in all this research and what will guarantee to work?

Residual valves are just check valves, there purpose is to help the pads and brake shoes stay close to the rotors and drums.

Instead of me smoking the keyboard have a read here;
http://www.mpbrakes.com/technical-su...igurations.cfm

you should be able to find the answers you are seeking. Brakes are a simple hydraulic system and power brakes just have the added benefit of vac assist.
happy reading..,

Fatman says....

Answer to the first question about rear tires.....225x75x15. I know that really large tires would play havoc with the system, but I don't think this is the case. Second question answered is that Fatman said that there are only 2 residual valves in their system and no proportioning or metering valves of any kind. They also indicated that the booster may be the problem, but I would have to troubleshoot the system as it may be a combination of several things. Since they have been making the frames they have changed a lot of their technology, such as different types of MC, boosters, etc.... Progress! Thanks for the recommended reading material, truly interesting!

I would check your vacuum. I am having some new problems with my sbc 355 as I am having some vaccum issues now. I was running about 18" steady and power brakes worked fine. 7" booster, dual cyclinder with prop valve. Disc brakes front, drum rear. Stopped fine. Now I'm running about 15" of vac and there is virtually no power brakes, they are really stiff, but it does stop.

I would get vac gauge and see where you are at. I have mine connected to the manifold. Does the engine run ok, idle fine, have good response. No bogging etc.
