Hello,

Please bear with me - I am just beginning to dabble into brake work. Three questions below.

For a long time now, I’ve had a scrape-scrape noise coming from the rear wheels (especially driver’s side), the cause having been narrowed down to the E-brakes with the help of this board. When I turn the wheels by hand, there is a scraping sound at one point during each turn.

I am adjusting the brakes by turning the star wheel on the adjuster through the opening in the brake rotor. On the passenger side, this was successful. On the driver’s side, I have turned the star wheel as far as it will go, but there is still residual drag. Question 1: What to do?

There is one thing I noticed, but am not sure if it is of importance here. On both sides, the rotors aren’t “true” - what I mean by that is, when I spin them, they get closer and farther from the inside edges of the brake calipers (I have the pads out to deal with a sqeal issue). We are talking very noticable wobble, perhaps 1/4 inch. This makes me wonder if the hubs and/or rotors are mounted properly. I feel stronly that this is related to the E-brake dragging. Question 2: I wonder if this is normal?

I want to take the caliper and rotor off to inspect the E-brake. Haynes says new caliper mounting bolts are required every time the calipers are removed. Question 3: Are new bolts absolutely necessary? Are they standard ones or specialty (i.e. need to get from dealer)?

Any hints will be appreciated.
