18. The brake cylinder may be pressure tested. The piston should be tested with oil pressure. The oil pressure must be regulated. The pressurized oil is piped into the pressure side of the brake system. A valve and a pressure gauge is incorporated into the pressure line. You should install an overflow hose. You should pipe the overflow hose into a plastic container. The plastic container is placed in the center of the brake assembly. The oil pressure must be set at 40 bars or 588 psi. Apply oil pressure. Shut off the valve. Watch the pressure gauge. The pressure gauge should not drop below 38.5 bars or 566 psi over a two minute time period.
