If you help me fix this, I will buy you a month on TRS!!
Ok, my brakes have some issues that I haven’t been able to figure out.
From the begging.
Started a year or so ago. The setup at the time was dana 35 calipers with slightly longer soft lines and 2 ½ inches of lift. No back brakes with master plugged at back brake port. At times I would loss the brakes. 3 years before this running the same setup it was fine. Quick pumping of the peddle would get them back. Things I checked where air in the system, loss wheel bearings, and the soft lines. All ok. So I ran it as it was ok.
Then I redid the lift and front end. 4+ inch custom flexy lift. Extended soft lines. At first the brakes worked great. But then it started to exhibit the some symptoms as before. After turning I would loss brakes. Peddle would go to the floor. After a few quick pumps I would get them back. Same things checked again, air, wheel bearings, soft lines and hard lines, all ok.
Then I did the 44 knuckle swap. Brakes worked great for the first few months as they where bigger. But then one wheelin trip this fall it started doing the same thing but really bad. After turning I would loss brakes and couldn’t really get them back. Things done trying to fix it. Swapping in two other master I had and then finally getting a new one. Didn’t help at all. Extended steel braided soft lines, did nothing to help. The only way I can get the brakes or brake to work is one hard line right to the driver side soft line. With this configuration I can run one front brake and it works fine.
For the front one hard line to a tee, off the tee the driver side soft line then a hard line over to the pass side soft line.
Now the really weird thing. After getting a peddle I move the truck and turn peddle goes to the floor. I pump the peddle get one back. Then with the truck just sitting fluid flows back to the master as something is pushing fluid back through the system. Both calipers are good. Swapped them from side to side, swapped other calipers on, but still the same thing. As soon as the pass side is connected all the gayness happens. The only other thing I haven’t tested by putting a different one on or replacing is the hard line form the tee to the passenger soft line. And it isn’t leaking anywhere. And I find it hard to believe that a hard line could expand and push back as much fluid as there is coming back to the master. And again the hard line does not move when the wheels are turned and that is the key factor to the problem. The wheels need to be turned in order to loss the brakes.
And don’t tell me to bleed the brakes trust me that’s not the problem. I have literally run a gallon or so of brake fluid through the system trying to fix this damn thing. Also the wheel bearings are tight. And as for the wheel wobbling or anything like that all the ball joints, tie-rod ends are all new. At any speed if the wheel is turned I loss brakes.
HELP, I DON’T KNOW WHAT THE HELL TO DO NEXT!!!!!!!!!!!!!!!!!!!!!
