Mount Or Reposition A Dual Pivot Caliper Bike Brake
Introduction
Dual-pivot brakes are simple to set up but the brake pads work in a particular way and need special treatment.
Step 2
Loosen The Caliper Brake
The caliper brake needs to be centred on the rim. Loosen the nut clamping the brake in the frame.
Step 4
Set The Shoes
Remove the pads if necessary, and lightly grease the threads on the mounting bolts and clamp the pads in position. The block on the side where the cable attaches moves down as it wears so this shoe needs to be set as high on the rim as possible. The block on the other side moves up as it wears so this shoe needs to be set as low on the rim as possible.
Step 5
Connect The Cable
Almost close the barrel adjuster and thread the cable. Hold the caliper closed where the pads are close but not touching the rim. Lock the cable clamp tight enough to grip the cable but not so tight as to crush the cable.
Step 6
Check
Apply the caliper brake to test it's operation.
Pro Tip
If the caliper brake won’t quite release screw the barrel adjuster right down to open the brake a little.
Step 7
Fine Balance
If necessary adjust the grub screw in the caliper brake arm to get balanced action from the two arms. Use small measured adjustments so if things get worse you can go back.
Step 8
Check
Apply the caliper brake to test it's operation.
Step 9
Finish off
Cut and cap the cable.
