Inspection, Adjustment & Lubrication
must be bled. Bleeding brakes takes special tools and training;
take your bike to your Gary Fisher dealer for service.
Check that there is no oil, grease, or other dirt on the disc. The
disc (Figure 3.7.6) is part of the braking system, so keep it clean
at all times. Remove the brake pads from the caliper during
heavy cleaning. Do not use cleanser, de-greaser, or solvents to
clean the disc. To clean discs, use isopropyl alcohol.
Once a month
inspect disc brake pads for wear. If disc
brake pads are less than 1.0 mm thick, replace the pads. Check
that the brake pads are in proper position, allowing 0.25 to
0.75 mm clearance from the disc when the brakes are not
applied (Figure 3.7.8). Spin the wheel; when the brake lever is
not pressed, the brake pads should touch as little
as possible on the disc.
Tighten the disc brake bolts (Figure 3.7.9):
• Caliper mounting bolts: 100-110 lb•in (11.3-12.4 Nm)
• Adapter mounting bolts using a 5mm allen wrench: 100-
• Adapter mounting bolts using a 5mm allen wrench: 100-
110 lb•in (11.3-12.4 Nm)
• Adapter bolts using 4mm allen wrench: 60-65 lb•in (6.8-
7.3 Nm).
• Disc attachment bolts holding the disc to the hub: 45-55
lb•in (5-6.2 Nm)
• Brake lever attachment bolts: 25-35 lb•in (2.8-4 Nm)
Check the brake hose for kinks or leakage.
Replace any part of hydraulic hose which does
not pass inspection. Replacing hydraulic hose
requires re-adjustment of the braking system
with special tools and training and should only
be done by your Gary Fisher dealer.
Adjustment
To adjust the distance from the brake lever to
the handlebar
1. Locate the reach adjustment screw between
the lever and the handlebar, near the lever
pivot.
2. To increase the reach, turn the screw in
(clockwise). To reduce the reach, turn the
screw out (counter-clockwise).
To align the brake with the disc
1. Loosen the brake mounting bolts.
