I've got a set of 2.0l Focus rear discs on my Mk5 Fiesta, however had issues with them leaking break fluid before i took it off the road. I'm planning to rebuild them now as it makes sense to do it.

Few questions really....

Is it hard to do, and are any specific tools required?

What will need replacing? Just seals, or pistons aswell?

Apart from Big Red, are there any other places to get the kits?

Thank you in advance,

Rob
