Section 4: Vehicle Operation

Hydraulic Brakes (if so equipped)
Your RV may be equipped with hydraulic surge brakes that operate automatically as the tow
vehicle’s brakes are applied. When speed is decreased and brakes are applied, the weight of
the trailer moving forward creates a reaction, which causes the brake fluid inside the wheel
cylinder to activate the brake shoes against the drum.
As a result of this design, backing the RV uphill may activate the surge brake system making
it difficult to continue in reverse. To aid in backing up the RV:
1. Prior to backing up a slope or through soft ground, pull the recreation vehicle forward
slightly to assure that the actuator socket is in the forward position.
2. Move the lever on the side of the actuator downward from the “towing position” along
the curved slot in the actuator frame to the “backup position.” The slot has a notch at
the bottom of its travel. Push the lever down to engage the locking notch.
3. The RV will now back up. This lever will slide into the correct position when pulling
forward.
It is extremely important to keep the master cylinder full at all times. An empty cylinder
invites moisture.
Disc Brakes (if so equipped)
If your RV is equipped with disc brakes, see the manufacturer’s owner’s manual for detailed
safety and maintenance information.
