Took my 40 for the first test drive today after a year of working on it. The brakes suck! What is your experience with a 4 wheel disc setup that has a 1982 Fj 60 master and power booster that has just been rebuild. All new 3/16" dia. brake lines, mini truck front knuckles and disc brakes, new rear adjustable proportioning valve, new 1979-85 rear cadillac eldorado e-brake calipers with 1/2 ton chevy rotors. I have bled the system many times, both ways. The "old pump till the bubbles disappear and then hold way" and I have pulled a vacuum on the calipers with a mini vac and a collection jar. I have a pretty good pedal, but I don't seem to be able to apply enough pressure to lock the brakes up, even at slow speeds.. 15mph going down about a 15 degree grade. I am running 35 x 12.5 tires. So, what's the consenus?Master to small? Anyone else run this system with better success than I'm having?
