CONVENTIONAL BRAKE SYSTEM

P-13prose procedure

2
Apply 66.7 kPa {500 mmHg, 19.7 inHg} vacuum to the power brake unit with a vacuum pump.

3
Invert the adjustment gauge used in Step 1 and place it on the power brake unit.
4
Measure the clearance between the end of the gauge and the push rod of the power brake unit. If it is not 0 mm {0 in}, loosen the push rod locknut and turn the push rod to make the adjustment.

NOTE

This adjustment produces the following distance.

Condition	Push rod-to-piston clearance
When vacuum applied to unit is approx. 66.7 kPa {500 mmHg, 19.7 inHg}	0.1–0.4 mm {0.004–0.015 in}

When vacuum applied to unit is approx. 66.7 kPa {500 mmHg, 19.7 inHg}

1
Disconnect the sensor connector.
2
Connect an ohmmeter to the connector.
3
Starting with the fluid level above the MIN mark on the reservoir, verify that there is no continuity.
4
Remove the brake fluid and verify continuity when the level is below the MIN mark.
5
Replace the sensor if necessary.
