Adjustment instructions

Brake pad holders have a front and rear. If the holder is facing the wrong direction, the pad could slide from the holder when the brake is applied. Make sure the Bontrager logo on the brake shoe holder is facing up and that the open end of the holder faces the rear of the bicycle.

To adjust the brakes

1. Center the brake. Loosen the brake attachment bolt, move the brake until both pads are the same distance from the rim, and retighten the attach- ment bolt to 70-85 lb•in (7.9-9.6 Nm).

Small centering adjustments can be made by simply rotating the center bolt with a 6 mm allen wrench (Figure 8).

2. Loosen the brake pad attachment bolt.

3. Align the pad, and squeeze the brake (or the

brake lever) to hold the pad aligned against the Figure 8 Center the brake rim (Figure 9).

Toe-in prevents squealing, and is usually only needed

 

with new brake pads. To achieve correct toe-in, you can put a business

 

card between the rim and the trailing edge of the brake pad prior to

 

holding the pad against

the rim.
