Possible cause: Foreign material in the
brakeunitassembly.
Remedy: Clean thoroughly. Replace the
shoes and linings if contaminated.
Possible cause: Insufcientamountofhy-
draulicuid.
Remedy: Fill the reservoir and bleed the
brakes. Check for leaks.
Possible cause: Brokelinesorpinchedline.
Remedy: Replace faulty lines and bleed the
brakes.
Possible cause: Seized actuator master
cylinder that prevents the piston from
stroking.
Remedy: Replace actuator master cylinder.
Possible cause: Corrosion/rust keeps
brakefromoperating.
Remedy: Replace damaged components or
entire brake assembly as required.
Problem:
One brake is overheating.
Possible cause: Disc brake caliper does
notpermitthebrakepadstorelease.
Remedy: 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 cav-
ity. Replace the piston, seal and protective
dust cover boot. Bleed the brake system.
Possible cause: Leaky or seized brake
wheelcylinder.
Remedy: Replace/rebuild the wheel cylin-
der and replace the brake shoes if contami-
nated with brake uid. Clean the drums
and other hardware; readjust the brakes and
bleed the brake system.
Possible cause:Damagedorfrozenbrake
mechanism.
Remedy: Rebuild or replace the brake unit.
Problem:
More than one brake is overheating.
Isolate the problem to the actuator or the
brakes by:
1. Fully extend the actuator.
2. Remove the master cylinder reservoir
plug.
3. Check that the reservoir is properly
lled.
4. Manually push the actuator inner mem-
ber in or use a screwdriver to stroke the
push rod.
5. In the rst 1/8” of stroke, the reservoir
uid will either remain dead calm or
swirl around. If the uid swirls, uid is
allowed to return to the reservoir when
the actuator is extended. This means the
actuator is functioning properly and it is
necessary to troubleshoot the brakes.
Possible cause: Trailer has been stored

causedthebrakestofreezeup.
Remedy: Remove the brakes. Clean, repair
or replace the components as necessary.
This is best done by an authorized Master-
Craft dealer.
