Retro Newbie
Evening all, I started out what I thought was a relatively simple job and have no idea what I've done wrong. I've got Hope C2 callipers and pro levers on my Pace RC200 F8 and one of the pistons on the rear calliper wasn't retracting properly and rubbing. This seems a pretty common complaint from reading around the Internet, so I thought I'd strip it down, replace the seals while I was at it, and lube it up. I got a proper Hope seal replacement kit off eBay, got both pistons out with a bit of elbow grease and the track pump trick, gently smoothed down a slightly burred edge on one piston with some emery paper, replaced the seals, popped some silicon grease on and screwed the pistons back in. At which point they completely seized solid and refuse to move. I have no idea what I've done, but they won't unscrew now and won't move back and forth.
I've wound up making a right mess of the tops of the pistons trying to unscrew them again with too much force and have given up now. Pretty disappointed with myself for making such a boll*cks of this
FWIW the front calliper is untouched and working just fine.
So, two questions:
- is anyone familiar with this situation and knows a way to free these up again?
or, assuming I've destroyed it and it's beyond repair:
- what are my options for replacing them? I know I'll not get a replacement C2 number 3 calliper easily (although I can keep an eye out on fleabay). If I'm going to replace them with an alternative there appear to be two mounting standards from what I gather: IS and Post mount. The rear mount is 51mm between the mounts, so I guess this is 'IS' (and from it's age, too). The front brake seems to be held on with a combination of brackets on the forks and the axle. Can newer callipers be fitted with adapters and will I need to replace the disc and lever, too? I'd imagine it's sensible to change both front and rear so they match.
