Starting to realise my heavy brake dust on the front is being caused by the rear not working. Are they refurbishable diy or do they have to be sent away?

If they are brembos then yes its a diy job, not easy and depends if the pistons are siezed

I suspect the pistons are seized. Would that mean not a diy job?

Looking at getting some secondhand calipers and putting new seals in. Anyone used 'Budweg' seals or recommend any others?

Are you sure it is the caliper? It could be the handbrake shoes, it has been known for the linings of old shoes to come loose and seize the disc.

It can still be a diy depends on your skill level, the costs would be quite high for pistons and seals, and the worst part is getting the bolts out, some cut the plates in half to split the calipers (I would never do that) that would add about £80 for new plates.

some times the brake hard lines are siezed in the calipers and you can break those as they are 20+ years old and corroded, the NS one is £62 the OS is £84.

if you are doing this job i would replace all the rear hard lines (4) and the flexi pipes as well,

could come to quite a bit of cash

I have done my own but I have a decent workshop with a pillar drill, lathe and the ability to shotblast. They were horrendous to get off and I had to drill out all of the bleed nipples and then run an M7 tap down them. I also had to drill out some of the brake pad retaining pins as well. Rewarding in the end but a lot of work and equipment. Mine were in a bad way though, I must get round to posting some photos. It might be easier to get some used but decent ones.

Well, have done a temporary fix on the brakes. Transpires the pistons were fine. The pads were stuck in the plates, flexifiled the plates and filed the edges on the pads to clean off the rust now they all work and yes brake dust on all wheels!
Temporary because of filing the pads, but also the dampers fell apart, brake wear sensors are just hanging on.

Any advice on were to get brake parts from would be much appreciated. I would need the bolts for the plates, new sensors, dampers and discs

FAR more likely to be plate lift, as opposed to seized pistons. Simple way to tell is to change the pads: if they fit easily then its worse than I thought. If they don't fit then you've got plate lift, which isn't terminal and everyone suffers from it. Us, Ferrari owners and anyone else who used the Brembo caliper.

Pan head high tensile 6mm x 16 bolts from eBay (I got a bag of 40 for £5), car parts for less has the sensors about £7 each last time I looked, discs on eBay £39 each, and dampers if you feel you really need them are expensive everywhere

Oh yes, its definitely plate lift. Just not looking forward to attempting to undo the bolts (with whats left of the heads!) Might dremmel a slot.

Cheers for that. When you say " if I feel I really need them", do you mean just not to bother with them at all or are you talking about the condition of my existing ones ( sprung part is still sitting in the piston and the sticky circular plate is stil on the pad - so in 2 parts, so scrap)

Sorry, didn't see the conclusion when I posted.

No worries
