Stephan,

Hi, without a strip down of your brake its hard to tell what the problem could be. If you have not had the slider pins out or greased up then they could have worn or corroded. The slider acts as a "float" and allows the caliper to move horizontally whist attched to the housing.

If i were you i would strip down the brakes and see what you find after romoving both the top and bottom slider bolts.

I suspect it will become obvious once you see the components apart as to what has failed.

From memeory the top slider bolt has no rubber end, the bottom one does.

If you find thta this has failed either new part (sorry no number but Milners Off Road in the UK do them mail order) or full re grease using red rubber grease on the sliders and then check the rest and carry out at lease a re lube on all the slider pins.

Hope this helps.

Cheers

Thanks for that.

The horizontal float on the caliper is the same as the caliper on the opposite side, but the caliper in question has vertical play as well.

I stripped the brake assembly in question over the weekend, and it does seem that the slider is the problem.

The slider can only be purchased with a caliper. Luckily I have managed to source a second hand caliper with a good slider, so I think that will adress the problem, and I will end up with a spare caliper as well.
