I've searched the FAQ and searched the forum threads and haven't found an exact answer.
I installed a new MC into my FJ55 which has 4 wheel discs. I "bench-bled" the new MC after it was installed.
As my helper person was pumping, the rear MC reservoir went down in fluid level by about 80% to almost dry. It took 8 pumps of the pedal to get the fluid level to stop dropping. I bled from the passenger rear caliper several times and not much improvement. When the brake pedal is released, the fluid slowly belches back into the reservoir to original fill levels.
The front reservoir doesn't drain at all and remains the same when the brakes are pumped.
Do I have a bad MC?
