I've read through many posts and hoped I could get some help with this problem. Car is a 68 charger RT power drum brakes all around. Pedal is low and feels like a brick and has about 1" of travel. Brake warning system light stays on. Recently rebuilt my carb but noticed RPM changes when starting fluid sprayed along base of carb. It's the original Carter AVS carb. So I bought a FelPro gasket and doubled the gasket and tightened the carb. Still changes RPM when sprayed at the base, but much less.
Vacuum gauge says 17hg at idle, so I think I've read that should be enough to work the power brake booster. When I put my foot on the brake and start the car, the pedal does move down a bit like there is some action on the booster. I still have to bleed the brakes, check the wheel cylinders and drums, but I'm really hoping to avoid having to change the brake booster. Here are my dumb questions:
Do brake booster fail partially, completely, or both?
Am I asking for vacuum leaks with two carb gaskets?
Do you think it could be anything BUT the booster at this point?
Thanks very much for any direction and help!
