Evening all,

My rear left caliper seems to binding, had a look tonight and greased my sliders while I had the wheel off,but still no joy...they seem to release Ok when I stretch back the cable on the arm.

Would it be best replace the caliper as I guess these are spring activated to release?

Many thanks,

Matt

Did you grease the caliper piston when you did the sliders? This usually cures the problem.

probably needs new cables and the caliper stripping and rebuilding Smile

Would I be correct in thinking that when the handrake is applied the piston rotates outwards as it would when you press the brake.

thanks,

Matt

no, it just moves out in a linear fashion, it can't turn due to the peg on the back of the brake pad.

Ah, It maybe worthwhile me greasing up the sliders to see if that helps.

Many thanks Welshpug.

Just bought some Castrol high temp grease, hopefully that will help.

Thanks,

Greased up all the sliders, really was sliding fine and still no joy.

Im thinking the caliper has lost the bite to release fully.

I was thinking that, if it still sticks it means it's the piston rite?

I should have pressed the brake while the disc was off and worked in and out a few times to loosen it up.

Thanks,

Matt

I must admit I did have a funny sensation when we had that -7 frost, it sounded like a clunk when I released the handbrake.

Hi,
got the same thing at the moment, not a real problem. I'd go for the caliper piston personally!. Give the piston a good clean being careful!. Check seal and re lubricate with fresh brake fluid. You may need a new piston seal??, comes in kit form. Or go for a new/ remanufactured caliper depending on condition of you're old one?.
Hope this helps.

Oh, and the clunking would be where the pad is set in one position on the disc, and then releases itself suddenly due to being stuck to the disc because of surface rust due to damp/ cold weather.

All else fails pull back the plastic cover over the handbrake mechanism (as Mei mentioned) and clean out with a brush then spray WD40 in there, then pack it full of grease and pull the little lever where the cable goes back and forth a few times with some grips, should see that part of the caliper free up and stop the binding if thats the cause insted of rebuilding/replacing first.

That worked for me matey and hope that helps.

Hi Steve,

Yes problem all sorted, though I do feel I may re-do the procedure again (fire out the piston and wind back it back in - solved it last time)

Although I now have a squeaking from the front right.

Thanks,

Matt
