How to Manually Bleed the Brakes
Because of the importance of correctly performing this procedure, Malibu-Axis Trailers strongly
recommends that this be done only by trained service technicians at your authorized Malibu-Ax
-
is Trailer dealer. However, recognizing that brake issues arise and may have to be addressed in
situations in which the trailer cannot be taken to the dealer for repair, the following instructions are
provided with the understanding that they should be utilized only in emergency.
• Check that all hydraulic fittings are secure.
• Read and understand all instructions before starting.
• Two people are required for manual bleeding.
1. Remove the master cylinder reservoir plug and fill the reservoir with brake fluid.
a. Use either DOT 3 Premium (preferred) or DOT 3 regular automotive brake fluid. Follow the
instructions on the brake fluid container.
b. Avoid shaking the brake fluid container and pour fluid slowly to minimize air entrapment.
c. Let the fluid in the reservoir stand until it is completely free of air bubbles.
2.
IMPORTANT:
Before bleeding the brake lines, bleed the actuator master cylinder. Insert a
screwdriver through the hole in the bottom of the inner member and use short strokes to pry
on the push rod (while holding the safety release bracket up) until no air bubbles are seen
coming from the small orifice hole in the bottom of the master cylinder reservoir.
3. Start the bleeding procedure on the brake farthest from the master cylinder.
4. At the brake assembly, connect a transparent bleeder hose to the bleed screw fitting on the
wheel cylinder and submerge the free end into a container partially filled with brake fluid. Do
not reuse this fluid.
5. The first person should stroke the push rod slowly while holding the safety release bracket
up.
6. The second person opens the bleed screw fitting.
7. He then closes the bleed screw fitting
BEFORE
the first person
SLOWLY
releases the push rod.
8. Repeat this procedure until the fluid expelled from the bleeder hose is free of air bubbles.
9. Remember to always tighten the bleeder screw before releasing the push rod. During this
procedure, the master cylinder reservoir fluid level must be maintained at no less than half
full.
10. Repeat Steps 4-9 for the other brake, as well as the brakes on the front axle of tandem axles.
11. If installation is on a tandem-axle trailer, repeat the bleeding procedure on the rear axle
brakes for a second time to assure purging of all air in the system.
12. As a final check after bleeding is completed, stroke the push rod and check to be sure the
brake system is pressurized. This is done by attempting to rotate a tire around.
13. Push up on the safety release bracket to ensure that the push rod is in the released position.
14. After the bleeding is completed, recheck the fluid level in the master cylinder. Fill the master
cylinder reservoir to the indicator on the reservoir plug. Do not overfill.
Optional Electric Brakes
The Malibu (Axis) trailer features electrical brakes. The system uses electric power from the
towing vehicle to drive the hydraulic power source. In a breakaway situation, the electric power
is supplied by a breakaway battery connected to the towed vehicle brake actuation system. This
battery is charged by a charger built into the control circuitry.
The actuator reacts in one of three ways: primarily, it turns on when the brake pedal of the
towing vehicle is depressed. If due to road conditions it is desirable to apply only the towed vehi-
cle brakes, this is achieved by applying the manual override on the “in-cab” brake controller. In a
breakaway situation, the towed vehicle brakes system is applied by the breakaway switch, which
is explained elsewhere in this section of the Owner’s Manual.
The system requires “in-cab” electric brake control not provided as part of the system. The
system will operate from most electric brake controllers
WHEN PROPERLY INSTALLED.
Proper electrical wiring is
CRITICAL
for the performance of the braking system. Improper
wiring can result in damage to the actuation system or system failure after initial use. A pure
ground and direct power (+12 VDC) with fuse or circuit breaker (30 amp) are necessary to ensure
good performance.
Line losses and poor grounding will result in poor performance or total
