OK. This one is tough to describe. My brake pressure is fine. In fact it's solid. However, I do not get good stopping power. The pedal seems to almost bind up just when the pressure is starting to get really good. So as a result, I have to STAND on my power brakes in order to stop properly. I thought my Power Brake booster was binding - so I replaced it. It got a little better. I thought mebbe I had a plugged line (It will go to the floor if I release one the bleeder valves on the wheel cylinder). I had a lot of crud in the rear line - it's all gone - it got a little better.
I'm starting to think Master Cylinder or proportioning valve. So here's the situation. I am rebuilding a '68 Gladiator, and converted to power brakes using a system from a '71 Wagoneer. Brakes worked great on Wago, old system on truck worked. After swapping out - no worky. Can anybody tell me if the Master Cylinder and/or the proportioning valves are that dissimilar on these two vehicles? I don't want to throw $500 worth of parts at the brake system only to find out it was only one part of the equation that was wrong! I eventually intend to get it all rebuilt, but for right now, I wanna get it working acceptably so that I can DRIVE the stinkin' thing. (The brakes and drums themselves are in good enough shape). In that same vein, if I need a proportioning valve, does anyone out there have the correct valve for a 1968 Gladiator with power brakes (or know where to get one - JWJEEP says no have). I suspect anything from '63 - '69 would work fine as a substitute. If it's my master cylinder - I'll kneel down, and kiss each dollar I spend at NAPA for a replacement. Any help would be GREATLY appreciated. I've invested over $6K, and 2 summers, to have the money run low, and be stopped from roadin' by the stinkin' brake system - that shouldn't have been in question!!
