hi, my name is pete. I own the above car and having trouble with the brakes. the problem being, a hard brake pedal. it has 18 inches of vacuum going to the brake booster. I checked the check valve its good. the brakes have been bled. this car has a brake distribution block that's never been changed, could this be causing the problem?any help would be appreciated. thanks. I checked the brake booster by unbolting the mc, and with the vacuum line from the manifold connected, the plunger on the brake booster was activated(sprang forward).
