5C – 32 POWER ASSISTED BRAKE SYSTEM
(4) When the front brake system fails.
When there is a failure in the front brake system,
the fluid pressure from the front master cylinder
decreases. As a result, the balance between the
front and rear brake side fluid pressures is lost at
the control valve sleeve so that the control valve
sleeve moves upwards.
The control valve sleeve strikes against the piston,
thereby pushing the piston upwards.
Accordingly, the fluid pressure of the rear master
cylinder is not decreased and is applied directly to
the rear wheel cylinder to secure a sufficient
braking performance of the rear brakes. (See the
left figure.)
Valve Maintenance
In the case of fluid leak or other abnormalities, faulty
valve should be replaced.
Note:
The load sensing proportioning valve is not
repairable and must be replaced as a complete
assembly.
