Hey guys
Just a quick question about a problem i'm havin with my v brakes. It seems that when i brake i get a normal braking application but when i release the brakes only one side of the brake arm springs back into position, out of the way of the tire. The other just rubs against the rim. I had a look at http://sheldonbrown.com/canti-direct.html and tried adjusting the little spring tension thing but to no avail. Anybody got any other tips on how to fix this (i'm assuming) fairly basic problem?
PS ive checked wheel alignment it all seems to be in order.

You need greater spring tension on the side that isn't popping back. Apparently the tension screw can't provide enough. Have you tried to reduce the spring tension on the other side by screwing the tension screw there out? It is more about balance between the two sides than absolute strength.
Pop the spring on the 'weak' side out from the brake arm and bend it out a little more then pop it back in. Mechanic at my LBS did this when I had a similar problem and suggested it was a fairly standard thing to do.

Yep, this is the thing to do. It will fix it up a treat. V-brakes are pretty indestructible and they're designed to be serviced.jasimon wrote:Pop the spring on the 'weak' side out from the brake arm and bend it out a little more then pop it back in.

Hmm, tried to adjust the tension screws, didnt work. Even took them all the way out and tried to adjust the brake arms but that still hasnt solved the main problem, which is now the fact that the arms dont seem to be centered. When i pull on the brake lever, the right arm moves to the left a lot (ie towards the tyre) but the left one moves a little bit right, hits the tyre, and then doesnt pop back. It seems as though they arent in center, and if i center them by hand its problem solved until i pull on the brake lever again.
Any suggestions??

Re-centre your wheel. Sounds like it's not fully in the drop-outs.Tom Marius wrote:Hmm, tried to adjust the tension screws, didnt work.

I ride, therefore I am. But don't ride into harm's way.

That's exactly the type of behaviour that can be solved with the screws, though bear in mind that they can't force massive changes. I've had cases where I had to feed some cable through the clamp on top of the brake arm to centre it up first as well as tweak the screws to get it right.Tom Marius wrote:Hmm, tried to adjust the tension screws, didnt work.

The screws are like fine adjusters - to get bigger changes you will have to pop one arm of the spring out and tighten the coil manually as mentioned above. (Assuming your wheel is centered.)Tom Marius wrote:Any suggestions??
With the screws you actually want one all the way in (on the side that is sticking) and the other all the way out - it wasn't clear if this was what you did so I thought I'd clarify.

This is what i did in the end, plus taking off the brake pads and then adjusting them (lining them up better with the rim) also seemed to do the trick.
