AT the shop, we have a 68 ElCamino, someone did a drum to disc conversion on it, so it has: new master and booster, new calipers and discs, rear drum brakes rebuilt, drum proportioning valve.

the problem, the pedal is real hard, feels like the car dosen't want to stop. I'm going to drive the car tomorrow will update this.

the car also has low vacuum at the manifold supposedly 10 Inches at idle, I think the valves might be too tight,

anybody have any ideas,

Um...maybe a stupid ??? but does it have the correct residual pressure valves?
