HELP!

Been using the hardtail for a few months and now the rear caliper on the full suss has seized, any suggestions for getting it err……unseized?

Change the fluid.

Might as well buy a set of cheap Shimano brakes.

I took mine apart, fitted new seals and put clean fluid in. You can still buy a seal kit from Chainreaction and I got an Avid bleed kit from Epic solutions. Various tutorials/instructions online if you google it. Mine work great now, as new (although how long that lasts is anybody’s guess). In fairness though, I’ve had many years trouble free use until the last few weeks and the above service seems to have sorted it. I’m sure your local shop will do it for you if you’re not mechanically minded. Good luck. Hope you manage to sort it.

Remove calliper
Remove lever
Throw into nearest bin
Replace with Shimano Deore.

If you have to pay the labour to a shop to swap the seals maybe a piston or two and bleed, then is often better just to buy a cheap shimano disc
But all the bits are easy enough to get and it’s simple to strip the caliper down

yeah just buy some good brakes
