I have an 89 244 GL AT
Changed the passenger side caliper, did not clamp lines as they were hardened 30 years.
After changing, I noticed I had 0 breaks.
Inspected the lines from the cylinder to caliper to make sure they were tight, they were. The bleeder screws are tightened as well, no leaks.I attempted to get air out and bled it a bit.
I promptly replaced the driver's side caliper, thinking hey, let's bleed these babies and maybe that will fix it. Upon starting at the rear passenger, I noticed no fluid was coming out of the bleeder screw.
I skipped it, did the rest, and they produced fluid. They seemed like they had air trapped. So I continued to bleed. After performing this, it kind of felt like there was some resistance on the brake pedal, but nothing solid.
I took the rear passenger screw off entirely and nothing was coming out. Brake pedal still to the floor.
I am thinking there may be some crud stuck somewhere, but why now? =\
Brake pads were working fine before, although, I had to replace them because the pads had became so worn they were almost ground to the metal. I also noticed the brake pedal sank slightly lower than the default height sometimes, maybe due to low pads. I replaced the calipers because the passenger side had 2 stuck pistons. I didn't even bother checking the driver's pistons, just replaced the whole thing.
As I performed this, there was one point (while changing the passenger caliper) where the fluid might have drained to the bottom of the cylinder while the GF was refilling.
Also, the calipers are on the correct side. I checked 5x the original and new as well as the box and pictures online.
