OPTION 2: Adjust using the actuator arm on the brake caliper.
If you are not able to get enough adjustment using the barrel
adjuster, you may need to adjust the brake using the actuator arm
on the rear caliper.
1.
Adjust the barrel adjuster on the brake lever all the way in, and
tighten the set ring.
2.
Locate the rear brake actuator arm where the brake cable is
connected to the rear brake caliper.
3.
Using an allen key, loosen the brake cable nut that secures the
cable to the actuator arm so that the cable can slide freely
through the bolt.
4.
Slide the actuator arm forward until it stops, then back it off
about a half of an inch, making sure the cable slides freely
through the bolt.
5.
Holding the actuator arm position, carefully re-tighten the
cable bolt until it is tight.
6.
Check the brakes and make sure the work properly.
NOTE:
Be sure the brake is not TOO TIGHT, which will impede
performance and cause excessive wear on the brake
