I did a brake job a few days ago, and I haven't exactly finished it yet. I am using a grade 8 bolt on one of the caliper brackets up front because the stock bolt was rusted and sheared off. Also, I discovered one of the pistons on the other caliper was not retracting / detracting easily. The boot on it is torn. Other than that, everything is back together and "working" for right now. I have since purchased the replacement caliper and all new grade 9 bolts from subaru.
Anyway, I have a "clicking" sound coming from the caliper that has a less than useful piston. I am hoping that is the problem.. I bought Centric rotors and also centric premium pads. These don't work with the stock metal brackets that insert into the caliper. They just go in.. they say "with shims" but they don't include metal brackets, just backing plates on the pads. I hope these aren't too loose in my calipers... Anyone else run into this ? Do I need those little metal brackets?
