Note
•  Use a commercially available flare nut wrench when installing the SST (49 D043 0A0) to the master cylinder.
―  Flare nut across flat: 12 mm {0.47 in}

2.  Connect the SSTs as shown in the figure, and bleed the air from the SSTs and the brake line. (Bleed the air from the SSTs using air bleed valve A.)

3.  Inspect the rear brake fluid pressure when the front brake fluid pressure is adjusted to the level indicated in the table.

•  If not within the specification, replace the master cylinder.

Proportioning valve fluid pressure

Front brake fluid pressure (kPa {kgf/cm2, psi})

Rear brake fluid pressure (kPa {kgf/cm2, psi})
5,000 {50.99, 725.2}
3,500—3,700 {35.70—37.72, 507.7—536.6}
10,000 {101.97, 1450.4}
4,950—5,250 {50.48—53.53, 718.0—761.4}
