My 1987 pickup has made my mechanic more confused the a rubix cube. I went to do some servicing including adjusting the hand brake and to check and service the front brakes. A leak was noticed on the left caliper so a repair kit was purchased and that corrected. Now after bleeding the 4 lines we noticed that the brakes went straight to the floor. Pumped up the brakes and it builds up pressure and after resting for maybe 15 secs and depress the brake pedal it went straight to the floor.
The mechanic changed the brake cylinder and the same thing. After doing some checks he said that the left caliper was expelling air in the oil. So he block of the brake line to the left caliper at the brake cylinder and there was brake. He block off the same line where it joins with the brake hose and there was brake. After removing the block the brake pedal went straight to the floor. He then used a vice grip to clap the hose it self and when tested there was brake. He decided to put on a new brake hose but the problem persists. So right now every thing points to the caliper as being the fault but the odd thing is the caliper isn't leaking any oil since replacing the rubbers in it.
What do you guys think of this? This thing is driving me up the wall because I really want this fix soon.
have the same problem?
