PARTS DESCRIPTION CHART
Non-servo operation inspection
- If the pedal force and fluid pressure correlation is within the specification with the engine stopped and a vacuum amount of 0 kPa {0 mmHg, 0 inHg} , the system is normal. Standard power brake unit non-servo operation STANDARD POWER BRAKE UNIT NON-SERVO OPERATION CHART Vacuum amount at 0 kPa {0 mmHg, 0 inHg} Pedal force Fluid pressure 200 N {20.4 kgf, 45.0 lbf} 390 kPa {3.98 kgf/cm 2 , 56.6 psi} or more
Servo operation inspection
- Start the engine and depress the brake pedal when the vacuum reaches 66.7 kPa {500 mmHg, 19.7 inHg} .
- At this time, apply the indicated pedal force and if the fluid pressure is within the specification, the unit is normal.

STANDARD POWER BRAKE UNIT SERVO OPERATION CHART
Description
- Steering wheel vibrates in the rotation direction. The characteristic is most noticeable when applying brakes at a vehicle speed of 100-140 km/h {62.2-86.3 mph}.
- When applying the brakes, the vehicle body shakes back and forth. The seriousness of the shaking is not influenced by vehicle speed.
- When applying brakes, a pulsating force tries to push the brake pad back. The pulsation is transmitted to the brake pedal.
