So we replaced the pads, and later the calipers. About 3 weeks later the driver's side tire locked up/caliper seized.
I took both calipers off to be safe, sprayed both with PB BLAST, let soak, wiped off the gunk. Cleaned everything with Brake Cleaner, then sprayed the calipers with heavy duty silicone. I cracked the bleeder valve and squeezed the calipers back into position, and everything was fine it seemed although the brakes were spongy.
Two days later the tire locked up again and was smoking, and we had the warranty on the calipers so I went to replace the driver's side again and observed the reservoir (master cylinder) had ran dry. (Never noticed any leakage from the Banjo Bolt but there must have been some?)
Now, we don't know what to do except replace the master cylinder, because the brake lines are good (or so we suspect) but when we bleed the front valves on the driver's side, initially it bled well. A couple more bleeds to complete the job, and no more fluid was coming out at all.
We read to take the steel lines off of the master cylinder, place our fingers over the ends, and push the brake pedal to the floor. Fluid came out one port side of the master cylinder, but not the other...is this right port the side leading to the driver's side?
Pumping to our hearts content resolved nothing prior to this removal of steel lines, and nothing after. The fluid level in the reservoir never changed, and further attempts to bleed resulted in still no fluid from the valve.
So now? Replace the master cylinder? Try to decipher if it's the brake line on the driver's side? If so, how do you remove the lines on this 93 XLT?
