Basic Maintenance Procedures 

With the engine off, locate the adjuster barrel on the brake lever   
To tighten the brake, screw the barrel adjust out, or counter clockwise so it is moving 
away from the lever. This lengthens the cable housing and makes the brake activate 
quicker when pulled. 
 
Make sure when you check the brake after adjusting so that you don’t over tighten and 
cause it to drag when not applied. 
 
Once you have the brake adjusted the way you want it, tighten down the stop nut on 
the barrel adjuster, turning it clockwise or toward the brake handle. Turn the stop nut 
as tight as you can with your fingers. Do not use tools to tighten the stop nut. 
 
If you can’t get enough adjustment on the 
barrel adjuster, you may have to make an 
adjustment at the caliper end, or at the 
wheel. 
1. Reset the cable barrel adjuster. Turn all 

the way in counter clock wise to loosen 
the cable 

2. locate the retainer nut at the center of the 

actuator arm on the brake. Loosen 
retainer nut using an 8mm wrench so that 
the center screw can be adjusted.   

3.Use a 2.5mm Allen wrench to turn the 

center screw clock wise until you feel 
pressure on the brake, then turn screw 
counter clockwise ½ turn to loosen 
pressure. Tighten retainer nut. 

4. Readjust barrel adjuster on brake lever 

as described above until the brake is 
working smoothly and firmly without 
dragging. 

 
 
 
 

NOTE: It maybe necessary to remove the master link in the rear chain. This will 
allow you to spin the rear wheel and properly feel the brake for drag.

 

make sure 

you reinstall the master running the proper direction. See page 22.
