One of the pistons has seized on my caliper, obviously it's been like this for a while as my brake pads have worn down completely on one side and are almost brand new on the other, kinda like a diagonal looking brake pad if that makes sense to you lot, any ideas what might be causing this and what is the best way to fix it, cheers. As usual, I hope my explanation has made sense to somebody.
Hi spec brakes

How old are they? if less than 12 months they should do it for free under warranty anyway. my hi spec 325mm discs warped, they skimmed them free of charge under warranty. its worth a shot, it saves you having to mess around with re sealing them yourself, even if they are a bit older than 12 months give em a good clean and try blagging it, you never know could save you a load of time and money 
Hey Dobby, I got it fixed, it was just the seals, once i got the pads out of they way and took the old boot covers off I managed to move the piston about with a bit of force, Hi-spec said that it was probably because of the hole in the cover and it was losing pressure, but I got a repair kit and it fitted just fine, was simple enough to fit (easier with two pairs of hands) only thing now is that my brake pedal will not build up much pressure, so I'm thinking that because of the new seals and boots on the caliper this is having a knock on effect on the brake master cylinder and I need to replace that now as the old seals can't handle the new pressure if thats makes sense. Let me know how u get on mate, I had a few other problems but managed to fix them as well, nothing major but hopefully when I have the cash i'll get the new brake master, hope that helped mate.
