My brakes work good when the rpm's are up (highway driving).
But when I am in heavy traffic or coming up to a stop sign I only get one good pump and then the pedal goes real hard about half way down.
I have replaced everything with new parts; master, booster, front hoses, calipers, rear cylinders and lines, even the engine is new but no chnage. Actually the new engine did make a little difference as the old one had very low vacuum.
It seems like I loose vacuum at low rpm (under 1500), it has a Comp 268 cam, not too lumpy, would that cause this problem? Any other ideas?
Thanks
