Help! Caliper Rebuild

[grey lex]

How do you get the rubber boot onto the piston and keep the metal coil intact??

You need to put the rubber boot and the piston in the cylinder first and then carefully put the metal ring on the rubber

agreed, i found that putting the piston in first and fully depressing it was the easiest way.

The using some brake fluid on the rubber, slide in in the groove (don't bother trying to get the middle to fit around the psiton as yet).

Then i used a fine set of tweezers i use for removing/adding tappet collets to work it in around the rubber. It's a tricky job so have plenty of patience and room to throw things. Once the ring is secured in (start from one open end and work your way around - i dind't bother trying to insert it complete in the closed position), use a fine instrument to check the coil ring sits nicely in place inside the rubber and groove.

Once complete, then you can fiddle about placing the inner rubber around the piston and check once the caliper is connected again by inserted something inbetween the caliper jaws to allow the piston to petrude a little without either popping it out or being too difficult to squeeze back for re-fitment.

the manual, swear a lot at the cat way, if anyone knows an easier method, i'll get my time machine : )
