Hub brakes
A hub brake such as a coaster brake, drum
brake, or internal brake usually requires multiple
frame attachments and multiple adjustments.
Due to this complexity and the importance
to your safety of having the brake adjusted
correctly, we highly recommend that any
adjustment of a hub brake, or removal of the
wheel from the frame, only be done by your
retailer.
To remove a wheel with internal or drum brakes
1. Disconnect the brake cable. Push the cable-
carrier arm forward, and the cable clamp bolt
rearward, so the bolt aligns with the larger
diameter hole in the carrier.
2. Pull the cable clamp bolt out to remove it
from the carrier. Slide the brake cable stop
forward to remove it from the brake arm.
3. Loosen the brake strap bolt, the bolt that
secures the brake arm.
4. For a rear wheel, shift the shift lever to first
gear. Pull the cable housing out of the gear
cable housing stop. Turn the gear cable clamp
bolt until the washer flats align with the slit in
the cog joint bracket. Remove the cable.
5. Loosen the axle nuts, and slide the wheel
from the frame.
To install a wheel with internal or drum brakes
1. For a rear wheel, place the chain on the rear
cog .
2. Slide the wheel into the frame.
3. Loosely attach the brake strap.
4. Tension the chain and tighten the axle nuts:
• Front wheel: 177-221 lb•in (20-25 Nm)
• Rear wheel: 266-310 lb•in (30-35 Nm)
5. Tighten the brake strap bolt to 17-26 lb•in
(2-3 Nm).
6. For a shift cable, align the washer flats with
the hole in the cog joint bracket, and slide the
gear cable clamp bolt into the bracket.
Disc brakes
When the wheel is out of the frame, do not
operate the brake lever. With some brakes, the
pads automatically adjust their clearance such
that you will not be able to insert the disc.
To align a hydraulic disc brake
1. Loosen the brake-attachment bolts (Figure
3.21).
2. Fully pull the lever, and tighten the bolts to
100-110 lb•in (11.3-12.4 Nm).
To align a cable-actuated disc brake
There are three parts to this procedure:
A. To adjust the clearance between the right
brake-pad and the disc
1. Turn the fixed-pad adjuster (Figure 3.22).
2. If the pads can not be adjusted correctly in
this manner, follow the instructions “To adjust
the clearance between the left brake-pad and
the disc,” and then adjust the right pad.
B. To adjust the clearance between the left
brake-pad and the disc
1. Turn the cable barrel-adjuster: clockwise
to increase clearance, counterclockwise to
decrease clearance.
2. If the pads can not be adjusted correctly,
loosen the cable-clamp bolt and re-attach the
cable. Tighten the cable-clamp bolt to
53-71 lb•in (6-8 Nm).
3. After adjustment, turn the lock-nut
clockwise to make sure the adjustment does
not change.
C. To align the brake with the disc
1. Loosen the brake attachment bolts.
2. Slide a business card or other thin object
between the right brake pad and the disc.
3. Pull the lever fully, and tighten the bolts to
100-110 lb•in (11.3-12.4 Nm).
To remove disc brake pads
1. Remove the wheel.
2. With your fingers or pliers, hold the installation
tang of the brake pad and pull out the pad.
