I did the vac install, re bled, have no hissing and the assist feels fine, just have harder time stopping and pedal goes lower than it should. Also, while at drag strip the brake lights were on a few times all the way down 1/8 mile. Car also pushed thru and red lights sometimes at 8-10 lbs of boost. I had to panic stop the other day, and fronts did not lock. I may try re bench bleeding. I do have modern combination valve. Ive read that i shouldnt have converted to vac, as PM is best. Just my luck, as i sold PM. Also, there seems to be debate over MC types..24/36mm VS 24 mm. Im not sure which i have.
Thanks
