First lubricate the caliper camshaft. Next, lubricate the slack adjuster.
To ensure the grease thoroughly lubricates the camshaft, the slack
adjuster will need to be manually adjusted full distance in each direction.
Manually adjusting the slack adjuster will move the camshaft through the
entire range of motion and ensure proper lubrication.
1. Begin the lubrication procedure by installing the wheel chocks.
Release the spring brakes.
2. Rotate the adjusting nut on the slack adjuster counterclockwise to
move the inboard brake pad against the rotor.
3. The poppet on the caliper pressure relief valve will be held closed
by spring pressure to prevent the grease from escaping during the
lubrication process. With a light touch hold the poppet valve
closed. Apply the high temperature grease through the grease
fitting closest to the rotor first. Stop greasing when the lubricant
begins extruding out of the camshaft dust cover located between
the caliper and slack adjuster.
4. Remove the pressure relief valve from the caliper.
CAUTION: Failure to remove the pressure relief valve will
leave excess grease in the caliper. This will cause the brakes
to drag due to the excess grease pressing on the caliper
camshaft. Reduced brake pad life will result.
5. Use a flat blade screwdriver on the slack adjuster to hold the
adjusting nut locking pawl open and rotate the adjusting nut on the
slack adjuster clockwise until the caliper piston is fully retracted.
As the caliper piston retracts, excess camshaft lubricant forces out
through the pressure relief hole.
