I did not divulge every piece of information at the beginning of this thread. I did not want to complicate the issue since there were so many factors involved. Here is what we now know to be true. 1. The front brakes get tighter and tighter. The rear brakes are fine. 2. When I open the front caliper bleeder valve, there is a squirt of fluid. This indicates that pressure is being retained in the front brake lines somewhere. 3. When I opened the opposite side front caliper bleeder valve, there was no indication of retained pressure. Both rotors now turn freely.
This would seem to indicate that the brake hoses are not collapsed. If both brake hoses were collapsing, I would think there would be a squirt of fluid from each caliper. Yet, both front wheels were too tight to turn by hand until I released pressure from one of the bleeder valves. Once I released pressure from one of the bleeder valves, both rotors could be turned by hand.
Now please don’t be mad at me for withholding the following information. (Or, you can be mad if you want, just don’t tell me). I am using an adjustable brake bias on the rear brake line. I have it adjusted to the middle position. If this brake bias device is malfunctioning, perhaps it is not allowing the MC piston to return to the home position, even though the brake pedal push rod is loose and free. However, if that is the case, then I would think I would build pressure in the rear lines, since the two circuits are independent. Is it possible that the brake bias is hindering the MC piston from returning to the home position?
