Back brake binding

[White Noise]

hi all,
just had my bike in the garage to have the rear tyre change, as i have got my MOT due next month i asked then to look over it to see what the general condition was like. They said that it should be fine though the back brake was binding a bit, they didn't think that it was that serious.
The thing is i don't know what this actually means! does it mean the pads aren't returning to there rest position quick enough after the brakes are applied?
what can be done to stop this happening?
Cheers
WN

I'm guessing its a disc brake, probably dirt on the back of the pad, this pushing the brake onto the disc when it shouldn't.. it could also be blockage in the brake lines (probably not though) or the piston not returning properly

It could be quite a few things, probabaly nothing to worry about, next time you change the pads (might be a good time to do them anyway) make sure the piston and the back of the pad are clean, if no change come back and ask again

Edit: If it was bad it won't pass the mot, but they would have made a point of you doing something if it was likely to fail.. all it will do is wear the disc and pad faster, it wont lock the wheel up, after a ride feel the disc to see if its hot, if its untouchably hot then best get it sorted

Remove the pads then pump the piston(s) out a little bit (obviousy not too far as they will fall out) you can put a block of wood between them so they stay in place when you hold the lever. Clean all the muck off with brake fluid (don't use WD40 or petrol etc). Clean up the pad retaining pins as well, there might be a whole load of crap from the road all in the caliper. Give the whole thing a once over with brake fluid, and that should sort it. It's a good thing to do this every now and again, you can do exactly the same with the front brake also.
