Bkd rear calliper binding

[JAYJAYB]

Hi all my rear near side brake calliper is binding. I have took the calliper off and checked the sliders . They are all good. But I tried to wind the piston back using the calliper tool and even with extra leverage no luck.
I’d this a common thing.
It’s wearing out the rear brake pads much quicker than the other side. I can feel them binding. Is it strip down or replace calliper I guess. The boot on the piston looks in good condition.

Yeah really common to seize up, I bought two new rear ones from auto doc for £90 delivered iirc they take a couple of weeks for delivery though

eBay, and it’s quick job so no worries about spending £20 again in 5 years time

One of my fronts was binding a few weeks ago, so changed both, bought from Eurocarparts. If not the sliders sticking it will be rust on the pistons, water gets under the rubber seals if they are torn or loose.

If you find the product code, Eurocarparts list them in the Will It Fit info.
