Last week, I had the QuadCab tires serviced, and with the wheels pulled off, I took a look at the brake pads, and was disappointed to see the wear on the driver side front pads through the caliper windows. A few days ago, I pulled the calipers off to get the front rotors surfaced, and verified that the driver caliper pistons were the culprit as the inside pad was worn out after 25k while the outside pad was barely worn; the passenger front pads were virtually equally worn, and about half used up. I also found the driver hub assembly had purged a good bit of grease, and was quite a bit more difficult to rotate than the passenger hub assembly. At first I was very disappointed by this, but dug up my receipts and verified that the warranty for that hub expires at the end of this month, so I was able to get a new replacement hub assembly at no charge...dodged a $300 bullet there.
I went ahead and pulled the rear calipers off to clean and lubricate the friction mounting points on the pads and caliper housings with Sil-Glyde as I had done with the fronts. With everything put back together and pressure bled, the test drives while running errands were not as successful as what I had hoped, as the ABS light was back on intermittently instead of all of the time while ambient temperatures were in the 70s. When the temps dropped to the 50s-60s the next day, the ABS light was on intermittently albeit for much less duration. With the ABS light off, emergency braking worked well and did not trigger the ABS light, so that's nice.
I am hoping that the brake issues are winding down, with this last caliper sticking because it's a little tight and will wear in sooner than later. Winter and most of spring will be in the rearview mirror In 6 months, and I'll check the system out again. In the meantime, I'm keeping my fingers crossed that there will be no incidents with this ol' buggy. After installing 17 calipers, 8 hydroboost units, 2 master cylinders, 2 power steering pumps, and 2 steering gearboxes, I've had enough practice overhauling these brakes...spending all this time doing the same procedures over and over has been a real drag
