IMPORTANT! Read product Safety Data Sheet before use. Carefully read the BG Xpress® Brake Fluid Exchange System instructions before servicing or attempting to place this system into operation and installing or removing brake fluid from any vehicle. Refer to the vehicle owner’s manual for the required brake fluid for the vehicle being serviced. BG Xpress® is not compatible with DOT 5 brake fluid. DOT 5 brake fluid is not compatible with either DOT 3 or DOT 4 brake fluid. Brake system may be under pressure. Open fittings slowly. Use only brake fluid from a container that has an intact factory seal. Do not store open or unsealed brake fluid as it will absorb moisture that use could prevent brakes from stopping the vehicle effectively. Keep all hoses and tools away from moving engine parts. Check all brake lines and hoses for cracks and sharp creases that could impede flow. Store and dispose of used brake fluid in accordance with local, state, and federal regulations. Always follow vehicle manufacturer’s recommended brake flushing and brake bleeding procedures!

1. Turn V1 Tank Pressure knob counterclockwise to “CLOSE” (–). Press pressure release button located on top of New Fluid Tank (N) to remove pressure trapped in system.
2. Make sure ball valve on Pump Hose (P) is closed.
3. Connect air source to BG Xpress.® Pressure gauge should read “0.” Note: BG Xpress® contains an internal regulator and gauge to control main line pressure. This regulator is preset and should only be adjusted by authorized service personnel during servicing.
4. Remove fill cap from top of New Fluid Tank (N) and add BG brake fluid.
   Do not use DOT 5 silicone brake fluid or any non brake fluid products with this machine!
5. When New Fluid Tank (N) is filled to upper “Master Cylinder” marker, replace fill cap securely.
6. Attach soft rubber suction wand to Return Hose (R).

1. Place vehicle on a lift to gain access to brake bleeder valve(s) on each wheel cylinder. Break each bleeder valve loose and then close to make sure all are functioning properly. Replace any stuck or malfunctioning bleeder valves. CAUTION: DO NOT use bleeder wrenches to break loose stuck valves.
2. Lower vehicle to ground level and remove cap from master cylinder reservoir.

1. Turn S1 Suction Switch on BG Xpress® to “ON.” Use suction wand on Return Hose (R) to remove all of old brake fluid from master cylinder reservoir. For compartmental reservoirs, use mini suction wand to get out as much old fluid as possible.
2. Turn S1 Suction Switch to “OFF” (O). Attach appropriate Master Cylinder Reservoir Adaptor securely—this adaptor connection will be pressurized!
3. Make sure ball valve on Pump Hose (P) is closed. Connect Pump Hose (P) to Master Cylinder Reservoir Adaptor. Adjust V1 Tank Pressure knob clockwise (+) to achieve desired pressure on New Fluid Tank (N). Use vehicle OEM recommended brake system flushing pressure. If OEM recommended pressure is not known, set pressure at approximately 12 PSI.
4. Open ball valve on Pump Hose (P) to fill reservoir. This process will compress air in reservoir leaving a little space between adaptor and fluid level in reservoir. This will allow removal of adaptor at end of service without spilling fluid. Check closely for leaks around adaptor seal.
5. Once master cylinder has been pressurized, raise vehicle and go to farthest wheel from master cylinder, usually passenger side rear. NOTE: Always use vehicle OEM brake flushing procedures if different from those listed in these instructions.
6. Select appropriate size bleeder wrench. Turn S1 Suction Switch to “ON” (I) and slip end of suction wand into end of bleeder wrench. Place bleeder wrench on bleeder valve and slowly open valve. Watch New Fluid Tank (N) and close bleeder valve when fluid level hits bottom marker for wheel being serviced. Move to next farthest wheel from master cylinder and repeat procedure. If one wheel cylinder does not come clean with fluid allotted, complete all wheels, release pressure as described at end of this service, refill tank and flush all wheel cylinders a second time.
7. When all wheel cylinders have been flushed, turn S1 Suction Switch to “OFF” (O), and turn V1 Tank Pressure knob to “CLOSE” (–). Leave ball valve open on Pump Hose (P) to master cylinder and press Pressure Release button to release all pressure from system, including master cylinder.  Failure to release pressure from master cylinder will result in fluid being sprayed when Pump Hose (P) is disconnected from Master Cylinder Reservoir Adaptor.
8. Remove Master Cylinder Reservoir Adaptor and adjust fluid level as necessary.
9. Clean and install factory master cylinder cap.
   Always test brakes before moving vehicle!
