Rear brake pad rubbing

[Chris750]

Pushing my bike out of the garage yesterday I noticed if you listen carefully, on the rear caliper the brake pad is rubbing on the disk, very, very slightly.

The break themselves work absolutely fine.

I was just wondering, is there usually an adjustment screw on the calipers so that I can slightly adjust the distance the pad sits away from the disk.
There are small screws on there but I don't want to start randomly messing with my brakes.
If there is usually an adjustment screw on there I will then investigate which one.
If this is not the case, any recommendations for sorting this?

I suggest you take the caliper off, remove the pads, move the pistons out and give them a clean (brake cleaner or WD40) dont get WD40 on the discs or pads.

Push the pistons back in and replace pads (if pads are shiney then give then a gentle rub on a paving flag to get the shine off) then reattach the caliper(s).

Disk pads are normally free floating with no adjustment screws. The screws you can see are probably to secure the sliding pins that the pads sit on. It may well be that an accumulation of brake dust and road crap is causing the pads to stick a little rather than floating free. Just remove the pads and clean everything up to get it running nice and free again.

It is ok for them to rub a bit, most do anyway. If you feel the need then do as suggested and clean the brake dust and crap off the pistons using brake cleaner and a toothbrush.

You'd want to take the caliper off the bike (I dont mean disconnect the hoses), take the pads out and pump the piston out a bit to clean it properly - just be sure not to pump it so far that it falls out or you will need to bleed the brakes.

When reattaching, use a torque wrench if you have one and observe manufacturers suggestions with regards to threadlocking the bolts etc.

Something else thats worth looking at as its not been mentioned here here, the Sliding pin itself. My back pin had a bit of corrosion and crap on it to didnt allow the pad to return as it just catches on the dried up gunk. So i took it out, cleaned it with some wire wool, coppergreased it and they stopped the rubbing as the pads could return to their normal position.

Thanks for the replies.
If its not an easy fix I will leave for now as its hardly noticable.
I will check the pin and make sure its not a case of just removing road debris and if not then I will just get sorted next time pads need replacing.
