'72 disk brakes help

[Kevin1972C20]

Thanks Cool72, my vaccum line were pretty bad so I checked and was only getting -4 pressure. replaced the lines and am around -10 to -14 now. Havent check to see if that did it yet. Since the wheels are off I decided to play with the suspension a bit... who knows what I'll find.

Vacuum boosters require about 16-17" minimum to be completely effective. That low vac. you indicated would definitely contribute to lower pressure being applied.
