Direct-pull Cantilever Brakes
Adjust Brake Arm Tension
Now check your brake arm tension. The brake arms should have good spring tension,
which makes them release when you let go of the brake lever. If there isn’t much tension,
you may have to increase it on both sides. Undo both bolts one at a time, but don’t
remove them completely.
You’ll notice a small piece of metal poking out the backside of the brake. This is the
spring, and it slides into one of three holes on your frame or fork. Most brakes work fine
in the middle hole. To increase your brake tension, move the spring into the top hole. To
decrease the brake tension, move the spring into the bottom hole. Then tighten the
mounting bolt.
Lever Adjustment
First you’ll need to loosen off your brake cable bolt. You don’t
need to remove it completely. This will allow you to adjust
the brake lever’s reach. On the lever you should see a screw
or bolt on the inside close to the handlebar. This is the reach
adjustment screw. As you turn this screw you’ll notice the
lever move closer to the handlebar grip. Turn it just enough
so the rider can easily reach the lever, but not too far, as it
still needs to be able to move enough to pull the brake.
Now re-adjust and tighten your brake cable. This is where the
4th hand tool comes in handy, as it will grip and pull the
cable for you while you tighten the bolt.
Reach Adjustment
Once the reach is set up and the brakes are working,
your child may find the lever is close enough but hard to
pull. This is caused by high spring tension on the back of
the brake caliper. To relieve some of this tension, you
can push the spring in toward the wheel on both sides. I
use an old screwdriver that I’ve ground down to a have a
concave end just for this purpose, so it doesn’t slip and
gouge my knuckles. Push just enough so it gives a tiny
bit. You don’t want to push the springs too much as they still need some tension to pull
the brakes back outward.
