I have problem with my brakes... this has stumped everyone who i have asked even toyota.
After i replaced the rotors (slotted 4000 series) and pads (bendix 4wd) on the front i found the pedal pushed all the way to the floor.
So i bled the brakes, using a different colour brake fluid until the new colour came through at all 4 wheels.
This still didn’t fix the problem. So i presumed the pads just needing to be bedded in. After 2000km and some very careful driving it hasn’t gotten any better...
So the problem from the start.
When the car is off - no vacuum
The pedal is extremely firm and cannot be moved no matter how hard you push. It seems like the brake would work perfectly.
Once the engine is started and the brakes have vacuum the pedal pushes all the way to the floor. With about 50% braking force like there is an airlock in the lines. However, if you pump the pedal to compress the airlock the pedal simply continues to push to the floor. Like fluid is passing back past the seals in the master cylinder.
Last week it was taken into Toyota for a test drive, the head mechanic was convinced it was the master cylinder. Winner i thought only $600 for a new one and i would have good brakes.
today they replaced the master cylinder... and walaaa still the same problem now Toyota are ordering in another brake master cylinder as they are concerned that the master cylinder they ordered could be faulty.
Has anyone ever experienced this and found the fix as i am concerned that the problem may be outside the Master cylinder... What is the chance that i would get a brand new farked master cylinder?
