aligning the front brake(5 posts)

I was wondering how you adjust the aligment of the front or rear brake, I assume it's the same for campy/shimano. The wheel is closer to the right pad than the left, bad bike store.
Thanks

If you haven't tightened down the mounting bolt that holds the brakes onto the frame to tight you can grasp the brake shoes and pull the brake calipers to the opposite side from where it is draging.
The mounting bolt can be a VERY LITTLE lose to allow this adjustment. The brakes will need to be checked for just about every time you remove the wheel. To check the adjustment of the brake pads, look at the top of the tire over the calipers and slowly aply the brakes and see which way the tire gets pushed. Then pull the brakes in the opposite direction. The calipers take an allen wrench to loosen. This works for Shimano brakes I assume it's the same for Campy.

You might also want to check to see that the wheel was built correctly and that the rim is square and centered on the hub. If the dish was done incorrectly, the wheel itself could be slightly off-center. In this case, the brake would be centered, but the wheel would not!

In addition to the brake alignment, you might also check the dish and/or trueness of your wheels. An un-true wheel might be closer to the brake pad on one side. Good luck.

First, make sure the wheel is straight in the drop out. The best and easiest way to check is to set the bike on its wheels and loosen and retighten the quick release. 90% of the time, this will correct brake rubbing problems.

If it still rubs, look at the brake arms. On newer bikes, one of the arms will have a screw in it. Tightening or loosening that screw will equalize the release spring tension on the two arms. When the tension is equal, the arms will move back simultaneously when you release the brake lever.

If it still rubs, make sure the screw we just talked about is in the middle of its range. Loosen the nut that holds the brake onto the fork, center the brake by eye and retighten the nut. After doing this, you may have to fine tune the spring tension screw again.
