TO MEASURE THE CALIPER GAP, use the steps below. The gap is

crucial to maintain brake effectiveness, because as the brake wears, the gap

increases, and the holding torque decreases.

PRESSURIZE THE BRAKE to 60 PSI min to fully release the clamping

force.

SHIFT THE BRAKE ASSEMBLY to the left until the right-hand pad

touches the rotor.

MEASURE THE GAP between the left hand pad and the rotor using a

feeler gauge. See Figure 13.

IF THE BRAKE GAP IS GREATER THAN .286 INCHES, replace

the pads, because the gap is crucial for maintaining adequate brake

holding torque. Pads may seem to have additional wear life at the time

when replacement is required, but the brake holding capacity is reduced

when the total gap exceeds the allowable amount.

Therefore, ALWAYS

replace the pads if the gap requirement is not met.

REPLACE THE GUARD PANEL on the back side of the winch after

checking both brakes.

2.3.2

INSPECTING THE STATIC CALIPER BRAKE (BEARING-SIDE)

REMOVE THE GUARD PANEL on the back side of the winch (If not

already removed) to reveal the brake caliper pads.

STATIC CALIPER BRAKE ROTOR should be inspected frequently for oil,

grease, and mechanical wear. If oil and/or grease are present on the rotor,

wipe the rotor clean with a towel or rag. If mechanical wear is found, locate

the source of the problem and contact factory to have the rotor and worn

components repaired or replaced.

STATIC CALIPER BRAKE PADS should be inspected frequently for oil,

grease, foreign contaminants, and uneven wear. If any unwanted materials

are found on the brake pads, wipe them off with a towel or rag. Replace all

the brake pads if one or more are worn unevenly, or if they have foreign

materials embedded in the friction surfaces.

MEASURE BRAKE PAD THICKNESS frequently to check for excessive

wear. See Figure 14. If either of the two visible pads is measured to be less

than 0.210 inches thick, replace all the pads. There is no practical procedure

for measuring the gap in the static brake.

REPLACE THE GUARD PANEL on the back side of the winch after

checking both brakes.

2.2.3

TEST BRAKES TO VERIFY HOLDING STRENGTH AFTER REPAIRS.

Brakes shall be tested per requirements of applicable standards, codes,

and regulations. Contact factory for information on unit-specific test

requirements.
