The following trailer maintenance guidelines are intended 

to assist the operator in preventive maintenance.

Properly functioning brake shoes and drums are essential 

to ensure safety. The brakes should be inspected the first 

200 miles of operation. This will allow the brake shoes and 

drums to seat properly. After the first 200 mile interval, 

inspect the brakes every 3,000 miles. If driving over rough 

terrain, inspect the brakes more frequently.

If your trailer has hydraulic brakes, they function the same 

way the surge brakes do on your tow vehicle. The hydraulic 

braking system must be inspected at least as often as the 

brakes on the tow vehicle, but no less than once per year. 

This inspection includes an assessment of the condition 

and proper operation of the wheel cylinders, brake shoes, 

brake drums and hubs.

Most axles are fitted with a brake mechanism that will adjust 

the brakes during a hard stop. However, some braking 

systems are not automatically adjusted by hard stopping. 

These brakes require manual adjustment. The following 

steps apply to adjust most manually adjustable brakes.
1.  Jack up the trailer and secure it on adequate capacity 

jackstands.

2.  Be sure the wheel and brake drum rotate freely.
3.  Remove the adjusting-hole cover from the adjusting 

slot on the bottom of the brake backing plate.

4.  With a screwdriver or standard adjusting tool, rotate the 

starwheel of the adjuster assembly to expand the brake 

shoes. Adjust the brake shoes out until the pressure 

of the linings against the drum makes the wheel very 

difficult to turn. Note: Your trailer maybe equipped with 

drop spindle axles. See axle manual for your axle type. 

You will need a modified adjusting tool for adjusting 

the brakes in these axles. With drop spindle axles, a 

modified adjusting tool with about an 80 degree angle 

should be used.

5.  Rotate the starwheel in the opposite direction until the 

wheel turns freely with a slight drag.

6.  Replace the adjusting-hole cover.

7.  Repeat the above procedure on all brakes.
8.  Lower the trailer to the ground.
Check the fluid level in the master cylinder reservoir at least 

every three months. If you tow your trailer an average of 

1,000 miles per month in a hot and dry environment, you 

must check the brake fluid level once a month. The brake 

fluid reservoir is located on the tongue of the trailer. Always 

fill with clean, uncontaminated DOT 4 brake fluid.
Figure 60 below displays the major hydraulic brake 

components that will require inspection and maintenance. 

Please inspect these components as required using steps 

1 through 6 as referenced in the “Manually Adjusting The 

Brakes” section on this page. See Table 8 for Hydraulic 

Brake Troubleshooting.

The hydraulic brake actuator (Figure 61) is the mechanism 

that activates the trailer’s brake system. This actuator 

changes fluid power into mechanical power. Therefore, the 

fluid level must be checked frequently to assure that the 

brakes function properly.
