RAM 2500 Truck 4WD V10-8.0L VIN W (1997)
This prevents air from being drawn back into the system. Do not allow the master cylinder to run out of fluid when bleeding the brakes. An empty
cylinder will allow air to be drawn back into the system. Check fluid level frequently during bleeding operations. Be sure to tighten each brake line
fitting, or bleed screw once bleeding is completed. Loose fittings and bleed screws allow air to enter the system.
VACUUM BLEEDING
If vacuum bleeding equipment is being used, it is not necessary to hold the front brake metering valve open. Simply bleed the brakes following the
bleed equipment manufacturers instructions.
PRESSURE BLEEDING
If pressure bleeding equipment will be used, the front brake metering valve will have to be held open to bleed the front brakes. The valve stem is
located in the forward end of the combination valve. The stem must either be pressed inward, or held outward slightly. A spring clip tool or helper
is needed to hold the valve stem in position. Follow the manufacturer's instructions carefully when using pressure equipment. Do not exceed the
tank manufacturers pressure recommendations. Generally, a tank pressure of 15-20 psi is more than sufficient for bleeding purposes. Fill the
bleeder tank with recommended fluid and purge air from the tank lines before bleeding. Do not pressure bleed without a proper master cylinder
adapter. The wrong adapter can lead to leakage or drawing air back into the system. Make sure the front brake metering valve in the combination
valve is held open. A spring clip tool is best for securing the valve stem in an open position.
