I’ve a '93 subaru impreza. It’s brakes are powder, so I bought new pads.
Lower pin out
Caliper swung up
Old pads out
Piston pushed back
New pads in
###!swing caliper back down
So the caliper swings up and down just fine, but won’t slide in and out on that pin due to some nefarious dried blood material that grew between the pin and threads. I guess the boot was slacking, the pin is rusted.
So I spray on the PB. I knock/bang/attempt to pull/wish I could pry/curse. I repeat. I repeat. I repeat. I wait a day. I repeat.
Do you have any magic methods for freeing up a caliper with a rusty pin? Or a way of getting the bloody thing over the new pads?
