Repair Help

TOE ADJUSTMENT: Toe is a pad setting that tends reduce brake squeal. If the bike does not squeal when used, then toe is not necessary.


For a brake to be toed, the pad is angled so the pad’s front edge strikes first. This reduces the tendency of the arms to flex back and forth, creating a harmonic resonance, which is the squeal heard during some braking.


Before setting pads, begin by double-checking that the wheel is adequately centered in the frame. If the wheel is moved from current position, pad alignment will be affected.

1. Loosen pad nut/bolt and lubricate curved washers and thread. Adjust one pad to the rim at a time.

2. If desired, install rubber band shim at back edge of pad. This helps to set the toe.

3. Push the caliper arm to the rim and view pad alignment. Align pad correctly in four positions.

o Set the pad’s vertical height on rim braking surface.

o Set the pad’s vertical face to be parallel to the rim’s face

o Set front and back edge of the pad to be level to the rim, so it is tangent to the rim.

o If toeing with a shim, set it so the front edge and back edge with rubber band should be touching the rim at same time.

4. Tighten pad nut and remove rubber band. Inspect pad alignment again.

5. Repeat alignment of other pad.
