I HATE working on our e-brakes.... so sis the previous owner of my car apparently. They had the e-barak apart at some point, and instead of reassembling they seem to have just dumped the parts in and slapped the rotor back on to hold them in. Fortunately when a part finally did seize I was only driving slowly down a side street.

Cost a TON to have that one side rebuilt.... a frigging TON. I was sooooo pissed off. No, I didn't rebuild it myself, one of the few things where I knew I didn't have the patience.
And yes, the pads are what 1/8" think new?
