All, I've always had weak brakes and think they should be much better based on what others say. I've got a '76 CJ-7 with 11" drums all around. I had 31's, then 33's, now
35's on the rear (might do a turn-around back to 31's 15 years later) and I've seen very little difference 'tween 'em all; always weak. I've changed master cylinder, wheel cylinders, drums and the whole works. I've bled them by gravity, pedal pressure and vacuum pump too. Still, WEAK; to the point that I have to stand on it as hard as I can to get a wheel to lock up in the rain if I'm lucky. I don't think there's a blocked line and everything's practically new minus the proportioning valve. Could the valve be the culprit from the start? Or, should I look for something else? If somebody has a troubleshooting scheme, I'd really appreciate it. Regards, Jim "Comin' Through!!!" Drinkwater- posted
