DCA-150SSKII — TRAILER BRAKING SYSTEM

Table of Contents

Brakes

If your trailer has a braking system, 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.

Electric Brakes

Electrically actuated brakes (Figure 2) are similar to hydraulic brakes. The basic difference is that hydraulic brakes are actuated by an electromagnet.

Listed below are some of the advantages that electric brakes have over hydraulic brakes:

An electric brake system can be manually adjusted to

provide the corrected braking capability for varying road and load conditions.

An electric brake system can be modulated to provide

more or less braking force, thus easing the brake load on the towing vehicle.

An electric brake system has very little lag time between

the time the vehicle’s brakes are actuated and the trailer’s brakes are actuated.

An electric brake system can provide an independent

emergency brake system.

Road testing is necessarry in order to properly synchronize the towing vehicle’s braking to the trailer’s braking. Brake lockup, grabbiness, or harshness is due to lack of

synchronization between the tow vehicle and the trailer being towed or under-adjusted brakes.

Before any brake synchronizations adjustments can be made, the trailer brakes should be burnished-in by applying the brakes 20-30 times with approximately a 20 m.p.h. decrease in speed, e.g. 40 m.p.h. to 20 m.p.h.. Allow ample time for brakes to cool between application. This allows the brake shoes to slightly be seated into the brake drum surface.

Figure 2 displays the major electric brake components that will require inspection and maintenance. Please inspect these components as required. Refer to Table 5 for electric brake troubleshooting guidelines.

Electric Brake Adjustment

1. Place the trailer on jack stands. Make sure the jack stands are placed on secure level ground.

2. Check the wheel and drum for free rotation.

3. Remove the adjusting hole cover from the adjusting slot at the bottom brake backing plate.

4. With a screwdriver or standard adjusting tool, rotate the star wheel of the adjuster assembly to expand the brake shoes.

5. Adjust the brake shoes outward until the pressure of the lining against the wheel drum makes the wheel difficult to turn.

6. Rotate the star wheel in the opposite direction until the wheel rotates freely with slight lining drag.

PAGE 14 —DCA-150SSKII— PARTS AND OPERATION MANUAL — REV. #2 (05/08/01)

7. Replace the adjusting hole cover and lower the trailer to the ground.

8. Repeat steps 1 through 6 on the remaining brakes.

Figure 2. Electrical Brake Components

Hydraulic/Air/Surge Brakes

Hydraulic brakes (Figure 3) should not require any special attention with the exception of routine maintenance such as shoe and lining replacement. These brakes can be adjusted in the same manner as electric brakes. Brake lines should be periodically checked for cracks, kinks, or blockage.

Figure 3 below displays the major hydraulic/air/surge brake components that will requrie inspection and maintenance. Inspect these components as required using steps 1 through 6 as referenced in the electric brake adjustments section. Refer to T a ble 6 for h ydraulic brake troubleshooting guidelines.

Tires and wheels are a very important and critical components of the trailer. When specifying or replacing the trailer wheels it is important the wheels, tires, and axle are properly matched.

CAUTION:

DO NOT attempt to repair or modify a wheel. DO NOT install an inner tube to correct a leak through the rim. If the rim is cracked, the air pressure in the

inner tube may cause pieces of the rim to explode (break off) with great force and cause serious eye or bodily injury.

Suspension

The leaf suspension springs and associated components

Tire Wear/Inflation

Tire inflation pressure is the most important factor in preserving tire life. Pressure should be checked cold before operation. DO NO T bleed air from tires when they are hot. Check inflation pressure weekly to insure the maximum tire life and to pre vent premature tread wear. Table 2 (Tire Wear Troubleshooting) will help pinpoint the causes and solutions of tire wear problems.

(Figure 4) should be visually inspected every 6,000 miles for signs of excessive wear, elongation of bolt holes, and loosening of fasteners. Replace all damaged parts (suspension) immediately . Torqued suspension components as detailed in Table 3.

CAUTION:

NOTE

AL WAYS wear safety glasses when removing or installing force fitted parts. Failure to comply may result in serious injury.

Lug Nut T orque Requirements

It is extremely important to apply and maintain proper wheel mounting torque on the trailer. Be sure to use only the fasteners matched to the cone angle of the wheel. Proper procedure for attachement of the wheels is as follows:

1. Star t all wheel lug nuts by hand.

2. Torque all lug nuts in sequence. See Figure 5. DO NO T torque the wheel lug n uts all the way down. Tighten each lug nut in 3 separate passes as defined by Table

3. After first road use, retorque all lug nuts in sequence. Check all wheel lug nuts periodically for continued safe operaion.
