Pretty sure they are identical to the RC24, pivoting on one pin with the other end of the pad held by the mounting plate

Remove the caps over the pins (use a decent screwdriver otherwise they chew), you may need an impact driver.
Remove the pins using a decent hex driver, use plenty of copperslip when rebuilding, both on the end of the pin, the thread and behind the 'cap'.

Well in that case, use plenty of plus-gas (not wd40) and possibly some boiling water[1] to try and free it.

Just sort your calipers out, put new brake fluid in and make sure there bled properly and they'll be much better.

Anything else requires major work (not worth it really)

The biggest problem is their sliding calipers.

People dont' grease the sliders with the right grease, this dries out the rubber seals and they seize up.

It'll cost you about £45 from dave silvers for a full set of seals and rubber boots to do all the calipers. Just use the right grease, decent pads and new fluid and there really quite good for sliders.

Braided lines help firm things up if you still have the original rubber hoses.

i could give that a go but the pistons inside come out when u pull the lever but then they wont go back in
are there any options at all for different better callipers?
cheers

Buy a big tub of red rubber grease from halfords, use it on pins, seals and everything rubber basically.

The reason btw I said not WD40 is that WD40 while better than nothing is simply a Water Dispersant, plus-gas is actually designed to penetrate and free seized bolts/nuts etc.

The pistons stick because salt and dirt builds up under the seals making them a tighter fit around the pistons. get new seals and clean out the small groves carefully before fitting your new seals and smear some red rubber grease on them and they will be fine.
