Brakes Not Operating Or Performing Poorly
Possible Cause Remedy
Worn out brake shoes
or disc brake pads
Replace the brake shoes/pads on
both sides of the axles and check the
drums/rotors for wear or damage.
Foreign material in the
brake unit assembly
Clean thoroughly. Replace the shoes
and linings if contaminated.
Insufficient amount of
hydraulic fluid.
Fill the reservoir and bleed the brakes.
Check for leaks.
Broken lines or
pinched line
Replace faulty lines and bleed the
brakes.
Seized actuator mas-
ter cylinder prevents
piston from stroking
Replace actuator master cylinder.
Corrosion/rust keeps
brake from operating
Replace damaged components or
entire brake assembly as required.
One Brake Is Overheating
Possible Cause Remedy
Disc brake caliper
does not permit the
brake pads to release.
Check the caliper. Sections must be
free to move apart. If frozen in place,
remove and free it up. Caliper piston
may freeze up and prevent pads from
retracting. Clean contaminants out of
the piston cavity. Replace the piston,
seal and protective dust cover boot.
Bleed the brake system.
Damaged or frozen
brake mechanism
Rebuild or replace the brake unit.
