Merry Christmas everyone. Over my holiday break, I'm going to try to straighten out a rear brake job which has kicked my @s$.
Long story short, I replaced:
- rear pads
- rear rotors
- driver's rear caliper with hose
- passenger parking brake shoes with hardware
- brake fluid, properly bled
All parts NAPA. Hardest part of the job was the passenger parking brake because it got stuck coming off and required about 8 hours worth of work to remove it (posted about it here).
I'm getting high rotor temps in the rear, particularly on the passenger side. Fronts are less than 100 deg F, driver's rear gets up to about 150-200 deg F, and passenger rear is close to 300 deg F, all after a 15-minute ride. Passenger side has a bit of a "hot" odor, but nothing that smells particularly distinct.
My 5th gen stays at less than 100 deg F at each wheel for the same period of driving.
I had it cooler for a period of time by backing BOTH parking brakes off completely, but since then I have tightened up on the driver's side (at the wheel) and surprisingly the passenger side got hot again. I think this might have been a fluke and just something that happened disassembling and reassembling the whole setup. I've rebuilt the whole parking brake on the passenger side twice now. Everything seems to move freely in the parking brake on the passenger side when the piston is compressed, even when the parking brake is properly adjusted.
Last thing to try is a new hose and caliper for the passenger side, as it's about the only thing that hasn't been replaced. Piston seems to compress ok, and it does float on the slide pins well, but I can't guarantee it's not dragging slightly at times.
Anything else I might not be thinking to check which can cause warm or hot rear brakes?
