Before I went on a 2500 mile roadtrip to see Eclipse, I insepcted my brakes, cleaned and greased the ways. I found the shim, which was riveted and glued to backing plate, had separated from the pad on the outer side of drivers side.
Hawk HPS pads on a 1989 dodge B250 light 3/4 ton, 5 lugs.
Brake calipers are Napa premium replaced at same time as HPS pads were installed on ~1 year old Brembo rotors. Most braking components have been recently replaced recently. Mileage on these pads is likely no more than 7K miles.
The sheared shim was on the outer pad, which is captive within the caliper.
I did not notice any other problems with brake pad and reinstalled without shim, greasing all ways and friction points and went on my road trip.
There was not a constant squealing but slight right turns at lower speeds would make high pitched brake noise, and it progressively got worse during the 2500 mile roadtrip. My IR temp gun revealed both rotor hats running the same temperature and MPGS were above expected so I did not freak out on the noise, as annoying as it was.
Today I returned home and inspected brakes on drivers side again. On a tangential note, I had to buy new tires along the way and found they had massively overtightened the lug nuts, I was barely able to loosen them with my 220 LBs and an 18 inch breaker bar.
Pulling off the brake pads revealed this:
These pads have been by far the grippiest pads I've ever used on this vehicle. Their stopping power gave supreme confidence compared to other most other pads which were anemic at best.
I was very impressed until recently.
Comments as to how, why the backing plate sheared off the rivets and glue, and as to why the friction material has separated from backing plate?
The stopping power and brake function is still excellent, but I will be replacing the pads anyway. Gonna fire off an Email to Hawk too, see what they say. They were not cheap.
