From previous post below - I've had this recurring intermittent shudder. Anyway this was isolated to a brake problem, so this evening, book & spanners in hand said I'd have a look. (front right wheel/brake)
First issue when on the jack was the wheel would only barely turn - vs a free-turning left side. So made fresh tea, put on some music & went at the brake. The caliper (the bit with the cylinder ?) was WEDGED down over the pads, permanently squeezing them onto the disc & pretty much locking the wheel. Took pads out & re-seated them (they're dead anyway - need new ones again) & all seemed well till caliper went back on - wedged again.
Does this mean its goosed (or do I just need fresh tea)

were you able to push back the piston in the caliper?
If its dead, you can pick up calipers easily enough now

or you could just replace the seals

My caliper was seized there just last week. Best thing is take out the piston and clean the rust off it and put it back in. Check the dust seal too it might be cut which lead to the rusting of the piston.

First check to see if the piston will move back. Shouldn't take too much effort

thanks guys. The piston appears to be totally siezed, so I've ordered a replacement. Already starting to feel like a fully fledged mechanic!.. Watch this space for updates .... and don't drive in front of me on the first outing

Bit of bleeding.... now I can stop again. Even had a short run on Paddy's day....
However, I now have a permanent hand-brake light showing -- any ideas
