Beginner brake help.
 

Hi all,

I am very new to cycling, so I don't really know what I'm doing.

I noticed one of my rear brake pads was rubbing, so I thought the cable might need loosening but it turned out that the callipers are misaligned. I looked up methods to realign them but it hasn't helped. The problem seems to be that the brakes are free to rotate around the locking bolt even when everything is fully tightened (my front brakes are rock solid). So when the brakes are released only one arm moves the other stays in contact with the rim.

Sorry if my terminology is a bit off. Cheers for any advice.

Bike is a triban 500 with shimano sora brakes.

Are the brakes caliper or vee ? If caliper their will be a small allen screw to even up the arm movement, usually on the rear arm at the top, unless they are really cheap ones in which case you can only try to centre them on the locking bolt. Undo locking nut place a cone spanner on the spring spacer hold in centre do up locking nut. If they are a vee brake you should have a little screw on each arm wind out to move the pad in and in to move away do this on both sides a bit at a time until no rubbing, activate brake after each adjustment.

Thanks for the suggestion cyclefar. I seem to have resolved the issue, it was mainly me being a simpleton. The locking nut wasn't tight enough against the brake itself allowing it to move.

Cheers. :thumb:
