Wife's car's brakes were grinding away @75k - I was ready to find an unusable rotor on one of the corners.
Pulled off the first (LF), plenty of meat left. Since i had the pads, i changed them out and greased the contact points.
Went to the right, found the same thing - took the flashlight to the back, and they were good.
When i pulled the caliper, the springs were missing?
it is a clip with outward pressure that bridges the inner and outer pad.
Next thing, the stainless backing plate falls to the ground as soon as i go to pull the outer pad.
looks like a clip broke.
Put it all back together with all the new h/w.
I think the grinding sound was that extra plate and the one under it moving around.
not sure how it is possible, but the noise is gone, and no rotors were damaged.
I may do the back at some point - but then i need to learn how to disable the eBrake.
