Bit of a service on my hope brakes (caliper no3) one of the pistons was a bit sticky, so gave it a shove and the seal failed. Popped the piston out and the seals nackered (luckily i have a spare set of seals), but the piston has a fair bit of corrosion on it. So go looking for new piston and so far have failed to buy the right ones. My LBS (4 so far) have all said they do'nt have them/cant get them. Wiggle sent the wrong ones (may be my fault - over eager ordering). So, where should i look for these pistons, 20.5mm dia hope caliper piston? Any (good) ideas appreciated.

Are they the metal cup type pistons?
I think you can replace with the phenolic type, they are about £5 each.
I would probably do both though so they are the same.

Alan, i'd seen that, but was slightly put off by the £5 postage for a £5 item. If i cant find them elsewhere may need to bite that bullet.

It does seem excessive.
Maybe a last resort backup...

Think I got my pistons from bike tart when I did my M4s.
