Checking for hydraulic pressure
WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
- When the engine is stopped (vacuum 0 kPa {0 mmHg, 0 inHg}
) and the fluid pressure is within the specification, the unit is operating.FLUID PRESSURE SPECIFICATION
Pedal force Fluid pressure 200 N {20 kgf, 44 Ibf} 590 kPa {6.02 kgf/cm2 , 85.6 psi} min. - Start the engine. Depress the brake pedal when the vacuum reaches 66.7 kPa {500 mmHg, 19.7 inHg}
.
- If the fluid pressure is within the specification, the unit is operating.
- If the fluid pressure is not as specified, inspect for damage to the check valve or vacuum hose, and fluid leakage of the hydraulic line. Repair as necessary, and inspect again.FLUID PRESSURE SPECIFICATION
Pedal force Fluid pressure 200 N {20 kgf, 44 Ibf} 8,780 kPa {89.53 kgf/cm2 , 1,273 psi} min.
