Grinding Rear brakes-uneven pad wear- 2015 MKX

Recommended Posts

Issue was that I could hear the rear brakes grinding when first driven everyday. Also after being parked for a longer time, the SUV pads would stick in place and the car would literally have to be broken free, when moved forward or backwards.


I pulled the wheels off and found one pad (on the piston side) worn down and the other pad was like new. So I assumed that the little pins were seized (under the bellows) and that the piston force was not being transferred to both sides of the disk. Upon disassembly, I found this was not the issue...pins were free and well lubricated. So I checked this forum and found no other posted issues with other solutions (there might be somewhere...) so I thought that I would just put in new pads and the problem wold be fixed. I bought the pads with the grease and spring/clip kit. When I assembled the pads, I noticed the pads fit very tightly into the new clips...so I removed the clips and cleaned the caliper grooves very well, but still found the pads very tight when reassembled. So, as a typical male, I thought I would just file the pads to fit looser in the clips and that is when I noticed that the pads and clips were not square...they have a notched shoulder on them...so I took the time to ensure that they were oriented properly and the fit was 100% better...still a little friction but no longer any binding...put it all back together with high temperature grease and the brakes are working fine....

Good job finding the culprit. Cleaning the caliper and reinstalling new clip h/w, as well as greasing the ears of the pads/clips is a must in order for the outer pads to slide freely and get pulled into the rotor when the brake is applied. 


What brake pad/clip mfg. did you use? Motorcraft?
