P30 Brake Lockup - Solved
I have a 1988 Pace Arrow on a P30 chassis with 4-wheel disk brakes. Recently, the brakes have been getting pretty mushy and brake fluid has been disappearing regularly with no external signs of leaks....

Today I got a chance to get underneath again and I think I solved the problem. I did 2 things, either of which or both cured it:
1) I loosened the bolts holding the MC to the booster and inserted flat washers between the 2 assemblies as shims.
2) Noticing that the brake pedal linkage seemed to be pre-loading the booster input rod a bit, I adjusted it a couple turns until there was noticeable slack,
I took it out for a long ride on local roads and there doesn't seem to be any more evidence of the pedal rising. The lockup is gone.
Thanks for all the suggestions
