reservoir. Check with your dealer for the type of brake 
fl uid used in the brake system.

9.2.3.2  Hydraulic Surge Brake

Before each tow, perform the following steps:

1. 

Check that the brake master cylinder level as 
instructed above. Check for leaks and repair as 
required.

2. 

Examine the actuator for wear, bent parts, corroded/
seized parts, or other damage. Have the affected 
components replaced with genuine service parts.

3. 

Check to determine that the actuator mounting bolts 
are tightened to the manufacturer’s specifi cation.

4. 

Test the actuator and brake function as described 
in the Coupling To Tow Vehicle section of this 
manual. Actuator travel over one inch indicates 
that the brakes need adjustment (or that the 
actuator has been structurally damaged). Actuator 
travel is the distance the coupler case assembly 
moves to the outer case during braking. Adjust the 
brakes following the instructions given in the brake 
installation manual. Failure to adjust brakes will 
result in loss of braking.

5. 

Before storage or after extended use, apply motor 
oil to the coupler components and the internal 
rollers to keep them moving freely and to prevent 
corrosion.

6. 

See the surge brake manufacturer’s manual for 
other inspection and maintenance activities. If you 
do not have this manual, contact your dealer for 
assistance.

9.2.3.3  Master Cylinder Bleeding

Remove the master cylinder’s cap and fi ll the 
reservoir to three quarters full with DOT-3 or DOT 
4 brake fl uid. DO NOT allow brake fl uid to contact 
painted surfaces since it will damage the fi nish. Wipe 
up any spills immediately and wash the area with 
water.

Bleed the brake system manually or with a pressure 
bleeder. Pressure bleeding equipment simplifi es 
the process, and is available at most automotive 
supply stores. Use the instructions provided with the 
pressure bleeder. If you chose to manually bleed the 
system, an assistant is required. Use the following 
steps to manually bleed the brake system:

1. 

Disconnect the trailer from the tow vehicle and 
jack the trailer’s tongue until it is horizontal. Make 
sure that the wheels are blocked so that the trailer 
will not roll away.

2. 

Fill the master cylinder with correct fl uid.

3. 

Install a bleeder hose on the bleeder screw of the 

farthest wheel cylinder from the actuator. If the 
trailer has multiple axles, bleed the rear axle fi rst. 
Submerse the other end of the hose in a glass 
container of brake fl uid, so that air bubbles can be 
observed.

4. 

Open the bleeder screw and have an assistant 
stroke (but not release) the actuator. Brake fl uid 
and/or air bubbles will fl ow into the jar. Close the 
bleeder screw. The helper can then allow the 
actuator to return to its rest position.

5. 

Repeat the process until no more bubbles are 
released with the stroke. Air trapped in the brake 
lines will greatly reduce your braking effi ciency. 
Be sure to close the bleeder screw securely when 
the cylinder is fully bled. Repeat the bleeding 
operation at each wheel cylinder. During the 
bleeding process, replenish the master cylinder 
reservoir with fresh brake fl uid so that the level 
does not fall below half full. This will ensure that 
no air is drawn into the system.

6. 

After all brakes have been bled, refi ll the master 
cylinder before operating. Be sure to install the 
master cylinder fi ller cap.

^

 

WARNING

Use only fresh brake fl uid from a sealed 
container. DO NOT reuse fl uid. After fi lling 
and bleeding, refi ll the actuator. 

Failure to maintain an adequate fl uid level 
may cause brake failure.

9.2.4  Trailer Connection To Tow Vehicle

9.2.4.1  Coupler And Ball

Before each tow, coat the ball with a thin layer of 
automotive bearing grease to reduce wear and ensure 
proper operation; and check the locking device that 
secures the coupler to the ball for proper operation.

See the coupler manufacturer’s manual for other 
inspection and maintenance procedures. If you do not 
have this manual, contact your dealer for assistance.

If you see or feel evidence of wear, such as fl at spots, 
deformations, pitting or corrosion, on the ball or 
coupler, immediately have your dealer inspect them to 
determine the proper action to prevent possible failure 
of the ball and coupler system. All bent or broken 
coupler parts must be replaced before towing the 
trailer.

The coupler latch lever must be able to rotate freely 
and automatically snap into the latched position. Oil the
