Centring V-Brakes

Tools: Cross Head Screwdriver
Time: 5 Minutes
 
 

V-brakes can be a bit fiddly at times. It doesn't take much for them to get knocked out of alignment while your rippin' it around the countryside. If the brake pads are not an equal distance from the rim on either side you may not have to muck about with the brake blocks themselves, you may just need to adjust the spring preload. Don't know what that is? Read on…

Because of the importance of efficient braking DO NOT attempt any maintenance on your brakes unless you are completely confident in your own ability.

1. Ensure that the wheel is sitting straight in the dropouts and spin the wheel round to make sure it isn't bent. If there is significant wobble then it needs truing. And if it does need truing make sure you get it done because you'll have crappy brakes and uneven pad wear if you don't.

2. If your wheel is nice and straight, turn your attention to the little screw at the bottom of the brake arm. This is the spring preload. The brake arm that is closer to the rim needs adjusting by turning the spring preload clockwise, which increases the tension and pushes the arm further away from the rim.
 

   

 
3. You can make fine adjustments using the spring preload on either brake arm until the brakes are centred nicely. Ideally, the brake blocks should be roughly no more than 3mm from the rim on either side. Remember that if the brakes pads are worn or uneven then they may need replacing, see Replacing Brake Pads.
