I've got a problem with my rear brakes that has me stumped. About 4 months ago I started to hear a squealing noise coming from the rear so I got some brake pads while in town. When I went to change the rear brake pads in my 05 Envoy I noticed a strange pad wear. The pad that sits against the piston of the caliper was worn way down and the outside pad still had plenty of life left on it, this was the same on both the passenger and driver side. Asking a question in a group I got told that I needed to, "Grease every part of the caliper including the slide pins and to use 'Silicone grease' so it helps keep to rubber soft." Following this I went ahead and replaced the brake pads making sure to clean the slide pins and the bores before replacing them and stuffing them full of silicone grease. And here I am 4 months later, I did my rear sway bar end links and while back there I looked at the pads only to see the same wear pattern.
So to sum up
Pulled from another forum because I couldn't get any suggestions there.
So to sum up
- The piston side of both rear calipers is keeping pressure on the pads even after releasing the brakes, causing the inner pads to wear down very quickly.
- The calipers are well lubed using 'Silicon Brake Lube' (Recommended to keep the rubber soft).
- This is the second occurrence despite pad replacement 3-4 months ago.
