The right rear wheel cylinder leaked so I replaced it and the short length of line leading to the cylinder. All was well for a few days ( about 40 miles of country paved roads) then the pedal went to the floor, I rechecked the res and found no fluid loss, tryed to re bleed the brakes but can not get ANY pressure at the rear wheels, both fronts develop pressure ok. I then proceeded to try bleeding at the 2 bleed screws on the ABS unit (attached to the master cyl.)(vehicle has 4whl abs) got good flow but NO AIR. I know how to bleed master cyl.s but this one has the ABS unit attached directly and I am unsure as to how the M/C bleeding proceedure is performed on this model. I am ASE master certified but never had to work on an integrated M/C ABS system. also thought that this was a "cross braking ' system but the fronts both work and both rears don't. any ideas????????????
