Operation Manual

Chapter 3: Adjustment 24
To put a direct-pull, cantilever, or road brake in
the center
1. Turn the center-adjust screw (Figure 27,
Figure 28, or Figure 29) in small increments.
2. If the brake has two center-adjust screws,
adjust the overall spring tension while you
put the brake in the center.
To adjust the alignment of the brake-pads on
a rim brake
1. Decrease the tightness of the brake-pad-
clamp bolt.
2. Align the brake-pads as shown in Figure 30.
Tighten the brake-pad-clamp bolts:
• Caliper: 40-60 lb•in (4.5-6.8 N•m)
• Direct-pull or cantilever: 70-80 lb•in (7.9-9 N•m)
3. After you adjust the brakes, examine them.
Pull the levers. Make sure the cable does not
slide through the cable clamp, the brake-
pads engage the rim at ninety-degree angles,
and the brake-pads do not touch the tire.
To release the brake for wheel removal
• For most road calipers, lift the brake release
lever (Figure 29) to the UP position. To close,
turn the lever to the DOWN position.
• For Campagnolo levers, push the release
button that is at the top of the lever. Slightly
pull the lever and push the button until it
aligns with the lever body. Release the lever.
To close the brake, follow the instructions in
the opposite sequence.
• For cantilever brakes, release the linkwire
(Figure 28). With one hand, push the brake-
pads fully against the rim. With the other hand,
pull the leaded end of the linkwire from the fork
on the brake-arm. Release the brake-pads.
To close the brake, follow the instructions in
the opposite sequence.
• For direct-pull brakes, disconnect the pipe
from the link (Figure 27). With one hand,
push the pads fully against the rim. With the
other hand, pull the pipe away from the link,
and lift the pipe. Release the brake-pads.
To close the brake, follow the instructions in
the opposite sequence.
• For internal or drum brakes, to remove the
rear wheel, first disconnect the gear and
brake cables.
To 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.
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. Decrease the
tightness of the brake-strap bolt.
To disconnect the gear cable, put the shift-
lever in 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.
