Had a squeak from my back wheel that sounded like it was coming from the brake disk rubbing, so took the pads out to see what state they were in.
Gave the lever a couple of pulls as well to see if the pistons were moving OK and one popped out with fluid going everywhere.
Wasn't sure if I could replace it but went ahead anyway then gave them a full bleed.
Got hardly any stopping power at all now and there's loads of play in the lever despite bleeding twice.
I'm assuming the pads are contaminated so need to change those anyway but are my calipers now also ruined or should I be able to just push a piston back in like I have?
