Reconditioning UK calipers


ADD

Recommended Posts

Unfortunately both my front calipers have seized, i got the brakes apart and found that 2 of the 4 pistons are seized badly, making the car rummble under braking (unsafe to drive) Does anyone know of either a member or company that recondition these?

 

thanks in advance

I got your mail, you seem to be saying they are now off the car? If they have stuck pistons you should have pumped them nearly all the way out hydraulically, using the foot brake.

If they are now on the bench the pistons will be all but impossible to remove, they will need connecting hydraulically again. My stainless steel pistons are £20 each, from memory a seal kit to do both front calipers is about £40. Prices are plus VAT and you also need the special square section seals that go between the caliper halves. 2 per caliper at £4.50 each.

Add, £500 and that does not include the pistons, they will only be changed should they find an issue with the pistons and I think there around £20ish. It does seem like a hefty price to pay but that all comes with a 4 year warranty on it working and also for the paint. Plus that includes them painting them in my custom colour (same colour as my car)

 

They do have a cheaper option without the paint which is around the high 200 mark.

If you want to enquire drop them a email quote, im speaking with a girl called Kyle or is it a bloke?

 

If you had the time I would suggest buying all the bits from Chris which is circa 450ish and doing it yourself.

The demand for pistons isn't great enough to have them CNC machined, so they are all done on a manual lathe! They take ages and because they are hollow they are wasteful of very expensive quality stainless bar stock. At £20 I sometimes wonder if it's worth it, but for CNC production to be viable I would need to order them in the hundreds and demand just isn't there. Some professionally rebuilt calipers I have dismantled have gold irridite coated mild steel pistons, not chromed steel, and I can assure folk they won't last long at all. Chrome is bad enough in a caliper environment. Irridite is for cheap nuts and bolts and Ikea furniture brackets, not caliper pistons :)
