... I was unsure about getting Britpart and the only real negative comments I could see were from people who felt similar to you in that they didn't want Britpart kit on safety critical items. However, any comments from people that had used them were positive in the fact they performed well. I think there were some comments that they may not last as long due to pistons suffering as the pads wear - but this would be apparent when you changed pads anyway...

Thanks chaps - Zee that's a useful list of suppliers. Will check the bleed nipples, else look to just change the pistons. Might be easier to just get some refurb calipers though but would haven't seen any with stainless pistons

Sorry for not comming back to you regarding this have been incomunicardo for a few days....

For calipers prebuilt with SS pistons : LOF have theses: https://lofclutches.com/store/brakes/brake...price-desc

For SS bleed nipples : I got a set from Pioneer 4x4 - they may not list them, but they do, do them

As for rusted pistons killing calipers, I'd say that the pistons kill the seals that leads to caliper failure, almost all calipers can be overhauled or rebuilt, those that are or have a genuine fault can go into a smelter and be recycled into new fresh cast calipers or any other thing from cast iron or steel. Zaid-M

If you want "go-faster Corsa red" calipers, buy new ones and paint them before fitting because it is cheaper in labour terms to do this than clean up old ones!.

BW, surely when it comes to brake calipers you would want them in “Go slower” red, yellow , silver or gold.

Ps. Any views on which colour will give the best braking performance

PPS. Great informative topic , when I need to replace I will follow advice and go for AP Delphi calipers plus dust caps, in fact I will be getting the caps now and look to change out bleed nipples as well on existing calipers.

Midway through the overhaul of a fairly gnarly set of Puma 110 calipers, I have to say that buying new ones is the sensible option.

My set of four is now shotblasted, fully stripped and cleaned up ready for paint, but this has taken about six hours of work so far. It will be at least double this by the time I have finished. Add to the bill stainless pistons, new piston seals, new gallery seals, and new bleed nipples, and it becomes clear that new calipers would have been both cheaper and quicker.

If you want calipers with stainless pistons, my advice would be buy new calipers and replace the pistons with stainless before fitting. If you want "go-faster Corsa red" calipers, buy new ones and paint them before fitting because it is cheaper in labour terms to do this than clean up old ones!

That said, overhauling a set is interesting, fulfilling, and appeals to my sense of "green-ness" (it seems wrong to send something that is 80% sound and usable to the recycler).
