Ian.Yeoman Posted January 30, 2003 Share Posted January 30, 2003 I have a nasty case of seized rear calipers ! Does anyone out there know what make and model of car the calipers are from or are they unique to Caterham ? My car is a 1.6K 2001 Link to comment Share on other sites More sharing options...

prs Posted January 30, 2003 Share Posted January 30, 2003 Ian, they are definitley the same as a 3dr Sierra cosworth as I've just fitted some to mine. I assume your handbrake mechanism began to stick they are notorius for that, good luck Phil Link to comment Share on other sites More sharing options...
Tight fart Posted January 30, 2003 Share Posted January 30, 2003 what makes you think they are seized ? if it's because you are fitting new pads and cannot push the pistons back, you need a tool that turns them as it pushes. Link to comment Share on other sites More sharing options...
prs Posted January 30, 2003 Share Posted January 30, 2003 Ian just noticed that your car is a 2001, no way they've seized in that space of time. As TF says you must use a special wind back tool on the piston that actually twists the piston back in, if you try to simply push them straight back as you would with front calipers you'll K-nack them....

Joe 90 Posted January 31, 2003 Share Posted January 31, 2003 I helped Ian with his brakes and I'm still mystified . The history is that Ian last used the car before christmas and is now upgrading it with a rear ant-roll bar. The problem with the rear brakes is that they are stuck on, and I don't mean just dragging a bit. It took over 200 ftlb to turn the rear hubs! The handbrake mechanism was off and there was no residual hydraulic pressure. The only sign of something untoward is that the dust seals are chewed up and split. Could it be that the very cold weather has shrunk the calipers? 99,000 miles so far Link to comment Share on other sites More sharing options...
STEVE GILBERT Posted January 31, 2003 Share Posted January 31, 2003 Has he had the car from new? Prehaps some monkey with water pump pliers has tried winding in the Pistons previously and buggered up the seals? R.E the tool if your too tight to shell out the £30 like I was you can easily knock one up out of 4mm ish Ali or steel plate, make it like a T, with the bottom of the T as wide as the piston and shaped to fit the funny profile of the piston crown. Best to wear gloves, grab the removed caliper, engage the key you have made, 1/2 turn back then clockwise in while pushing like hell. Easy peasy. Oh and slacken the handbrake off lots too. HTH but it probably didnt Steve See My Zetec Power 7 Here Link to comment Share on other sites More sharing options...
