Find an even disc-brake gap.

The Birzman Clam caliper alignment tool fits between the rotor and brake pads while you adjust the caliper.

Three-piece set

Stainless-steel alignment tools slide over the rotor and between the pads to help establish an even gap. Brake parts are not included.

Rotor fit

For compatible bicycle disc brakes with rotors no thicker than 2.3mm. Check caliper clearance before use.

Adjust and remove

Follow Birzman’s instructions and the brake maker’s bolt-tightening guidance. Remove the tool after adjustment and check brake operation before riding.
