rear caliper

[wayno]

took the bike for mot this morn, as its sorn this was my 1st real ride so was looking forward to it, took it along a quiet stretch of road to test the brakes, all ok so headed for the mot. when i got there the bike was reluctant to move into the garage, turns out the rear brake had stuck on so opened the bleed nipple a touch to release a bit of pressure and headed home..gutted. removed the pads but cannot budge the piston back into the caliper. depress the brake lever and the piston inches out. is a rebuild easy or can recon calipers be bought?

Usually new seals and a good clean up does the job.
Which model Z is it ?

thanks for the reply london, its a z1000 a1. only took the main stand off 2 weeks ago to fit an exhaust craft pipe. whats the best way to support the bike before removing the caliper with only a side stand

[chrisu]

eithera paddock stand or I've got an ABBA stand that pivots on the swingarm spindle.

has multiple adapters and I use is on all my bikes. More stable and easy to use.

LOL - I had this, actually it wasn't LOL.

check that the disc run out is within spec. they have tendancy to warp - mind did, also didn't help by have big boots for big feet and I reckon I must have rested my foot on the brake that of course made the situation worse.


and check the caliper is central about the disc - mine wasn't so one piston was more or less fully in so have nowhere to retract, fitting new pads didn't help the situation. (I did shim it out with a 1 mm aluminium disc that sorted it but managed to get a rear disc on ebay which is the proper way to fix it.

Changed the wheel bearings recently check all the bearings are fully home and up to the stops in the hubs

think i got it sorted with just a strip down and clean, pistons are now moving in/out and no problem sticking on.... of course this is in the garage so booked for mot sat morn, try again on the way there. hopefully i can at least get it looked at, if it passes or not is another matter.
