My Lexus had a soft pedal and it was really low so i decided to do a brake flush , once i took my wheels off i noticed uneven wear on the pads . Both Calipers ended up being stuck at the bottom pin ,Both had to be heated to be taken off . Just letting others know I have read a lot of posts about the soft brake pedal and this did the trick for me

Did you replace the caliper or just the pins? I may just do mine again but I have even wear on the rear pads.

Its always a good idea to remove the rear pads and lube the pins, and to spruce up the pads with grease. This also helps remove the squeels

Didn't replace the calipers , just cleaned and lubed everything
