The slide pins and grommets, caliper untouched. I’m thinking the handbrake isn’t releasing.
So I pulled the slide pins and added more caliper grease. Gave a quick blast of the components with brake cleaner. Still binding. Caliper piston winds back just fine.
took the caliper off and noticed the locating detail on the caliper piston was a bit too off center, having just wound it back into place. I swapped pads, thinking there’s no ducking way the caliper piston is sliding over the locating pin on the pads. Turn the car on, hit the brakes a few times to build pressure and displace the piston. Cycle the handbrake because it’s what the cool kids do, and turn the car off.
wheel spins fine. What the duck.
GODDAMNIT IS IS THE HANDBRAKE. The fucking return is sticking and the spring isn’t overcoming it. I had to whack it and it spring back and now works. Ended up blasting with brake clear and a little WD40 (shut up, it’s all I have in the garage) and cycled the action a tag. Repeated handbrake jerks and it’s fine.
