If you just changed the PM motor, fill the PM reservoir to the full line (you can see the level from inside the reservoir). The PM reservoir is the largest reservoir with 2 holes on the bottom. Turn the key on, engine off. the motor will activate and begin drawing fluid through the system. If the front port becomes uncovered, then add brake fluid until it just covers the front port (floor of the PM reservoir). It should run for no more than 20 seconds. If it does, you need to bleed the PM system. You do this by turning the ignition off and loosening the hose below the accumulator until brake fluidflows from the hose. THIS IS CAPPED FOR A WARNING: DO NOT UNDER ANY CIRCUMSTANCES COMPLETELY REMOVE THE HOSE, ACCUMULATOR OR PRESSURE SWITCH. WE ARE TALKING ABOUT 700PSI PLUS OF PRESSURE AND THE PM BLEED PROCESS IS ACCOMPLISHED WITH THE ACCUMULATOR STILL PRESSURIZED!!!!!! After bleeding the PM motor, key on, engine off and watch the fluid level on the PM reservoir side (the front port is the suction side andshould always be covered in brake fluid) and the PM motor should not run for more than 20 seconds. If you made repairs to the hydraulic side of the PM (the side that controls pressure to the brakes system), then do not fill the PM reservoir until you have bench bleed the master cylinder. Parts houses sell a bench bleed kit, so you can bench bleed the master cylinder with the unit installed on the car. Follow the instructions and pump the pedal until you don't see any bubbles fluid. Hook the brake lines up and bleed the brakes (you can gravity bleed at this time). After you have a solid pedal, then you can address the PM motor side. Bleeding of the brakes is accomplished with the ignition off.
