The brake system is divided into a primary and secondary circuit. The primary circuit right front and left rear wheel brakes.
When do the brakes no longer have power assist?
If you were to release and apply the brakes again, you would find approximately 30% to 40% assist, then again approximately 10% to 20%, until you have depleted all stored reserve assist.

Bad Brake Power Boost Unit: Finally, if your brake booster goes bad you’ll have low brake pedal issues. Most brake boosters are vacuum controlled, so a special vacuum measurement device that connects to the brake booster is needed to check it.
Where is the pressure sensor on a Saab 9-3?
The relay in turn is governed by a pressure sensor located on the hose between the vacuum pump and the brake servo. This sensor comprises a diaphragm, spring, switch and check valve. The switch closes to start the pump at a pressure of 49 ±3 KPa. When the pressure reaches 42 ±3 Kpa, the switch will open and the pump stop.

When to use power assist after engine stall?
In the event of a loss of pressurized fluid, the accumulator will provide two to three power assisted stops. Upon the first application of the brakes after an engine stall or loss of power steering, you would find approximately 60 to 75% of the normal assist available.
