How To Adjust the Brake
The caliper does have some float in it, therefore, it tends to re-adjust itself slightly each time the brake lever is released. If you are having difficulty
with your disc brake, follow these suggestions:
1.) Should the disc rotor noticeably deflect to one side upon squeezing the brake lever, re-adjust the disc bracket where it attaches to the frame and
center the disc rotor in the slot of the caliper. It may be necessary to back the brake pads away from the rotor to center the disc rotor. (Remember:
When you loosen this bracket the interface between the pads and rotor will be changed making it harder to re-adjust the pads without having
them rub. Also, if the rotor is not perfectly true it may cause a slight rub when adjusted properly. This will require some break-in time to allow
the pads to wear parallel with the rotor.)
2.) Adjust the brake pads before tightening the cable anchor bolt. Adjusting the brake pads with the cable detached, allows for a more precise
adjustment because there is no pressure on the internal spring in the caliper.
3.) Adjust the pads inward on both sides until the pads slightly touch, then with your thumb push the actuating arm of the caliper forward to mimic
the movement of the brake lever. It may take 3 or 4 times of this procedure to obtain the best adjustment.
4.) Once the pads are adjusted properly, you can connect the cable to the actuating arm of the caliper and tighten it down with the anchor bolt. The
actuating arm on the caliper should be at the 11-12 o'clock position when the brake is not being used.
5.) After the cable is secured to the caliper, squeeze the lever several times to see if the brake rubs. Now adjust the brake pads inward or outward
depending on if the brake is rubbing or if there is a space between the pads and rotor.
