The BrakeBuddy was designed and built as an auxiliary braking system to operate in conjunction with the existing braking system in your towed vehicle. Use of the BrakeBuddy in a manner inconsistent with these instructions may result in damage to your vehicle, serious injury or death. You must read and understand these instructions prior to the use of this product. If you have any questions after reading these instructions, please call BrakeBuddy customer service at 1-800-470-2287. 1.Remove the BrakeBuddy and components from the shipping carton. The complete system consists of: Main BrakeBuddy Unit Breakaway System Clevis Assembly Remote Alert System 2. Install the breakaway system by following the step-by-step instructions included with the breakaway kit. 3. Attach the lock nut and clevis assembly to the air cylinder (Fig.1). 4. Adjust the driver’s seat to the far back position (Fig. 2). Place the BrakeBuddy on the floorboard between the seat and the brake pedal. Slide the BrakeBuddy back against the seat for maximum working room. 5. With the notched end of the clevis facing up, attach the clevis to the top of the towed vehicle’s brake pedal (Fig. 3). Angle the brake pedal clevis so the upper portion of the clevis grabs the top of the towed vehicle’s brake pedal. Pull down on the air cylinder rod (or lower portion of the clevis) to extend the clevis under the bottom of the towed vehicle’s brake pedal. Pull back on the red locking tab (A) until secure (tab should not go all the way down). 6. Move the BrakeBuddy forward until the air cylinder rod is fully retracted (Fig. 4). Make sure the brake pedal is not being pressed. 7. Adjust the driver’s seat forward until it touches the handle on the back on the BrakeBuddy (Fig. 5). 8. Adjust the BrakeBuddy handle (Fig. 6). Loosen the adjustment knob on the back center portion of the BrakeBuddy and adjust the height of the handle so it contacts the seat at the lowest position possible without sliding under the seat. (NOTE: the lower on the seat, the firmer the support). T ighten the adjustment knob to secure handle. FIG. 3 A Move BrakeBuddy forward. Move seat forward.

Power the BrakeBuddy (Fig. 7). To power the BrakeBuddy, plug the unit into a 12-volt receptacle in the towed vehicle. When powered, the air compressor will fill the air tank in 30-40 seconds. If a 12-volt power supply is not available in the towed position (or the 12-volt power remains off in the ignition off position), a 12-volt Battery Direct Kit is available (part number 39305). At a minimum, a 15-amp 12-volt power supply is required to operate the BrakeBuddy. NOTE: The red “bleed brakes” light will be lit until completion of step 10. 10. Push the red AUTO START button located on top of the BrakeBuddy (Fig. 8). The arm will automatically extend / cycle 5 times. This will remove any vacuum stored in the brake vacuum reservoir of the towed vehicle as well as diagnose any errors in the system startup (B). NOTE: While the arm is activating, look at the brake lights on the rear of the towed vehicle. The brake lights will fluctuate on and off as the BrakeBuddy is pressing on and off the brake pedal.If the brake lights remain on,the BrakeBuddy unit is too close to the brake pedal. NOTE:After Auto Start cycle is complete, the red “bleed brakes”light will go out and the green “normal” light will be on. NOTE: The test button (Fig. 8 / C)is a manual (one time) arm activation test.The test button can be used to confirm the unit is in the correct floor position. WARNING:Any time the towed vehicle’s engine has been started (e.g., running through gears, charging battery, etc.) You Must push the Auto Start after shutting the towed vehicle’s engine off. This removes the vacuum out of the vehicle’s brake system. Failure to drain the towed vehicle’s brake vacuum will result in excessive tire wear . 11. Make final seat adjustments. If there is a gap between the seat and handle, adjust the seat forward to close the gap.
