Pressure regulator rear brakes
Pressure regulator rear brakes distributes proper brake fluid pressure in the brake circuits front and rear wheels to provide high performance braking and prevent the rear wheels locking and skidding. Pressure regulator rear brakes can not be disassembled, as its performance is strongly dependent on the tension of the spring installed in it.
Operability test Remove the rear brake pressure regulator to brake master cylinder. The check must be two pressure gauges. Connect the pressure gauge to the first regulator inlet fitting, and the second pressure gauge - fitting to the output of the regulator.
NOTE After installation, bleed the brake system pressure gauge. |
Press brake pedal and measure the current pressure on the inlet and outlet of the proportional valve. If the pressure value corresponds to that shown in Figure 6.20, then valve defective. Connect the brake pipes into place, bleed the brake system.

NOTE Characteristics of the proportional valve is shown in the case of increase in pressure (Fig. 6.20). |
Install pressure regulator rear brakes
Install the brake master cylinder, as shown in Figure 6.21. Tighten the nuts brake lines and bleed the brake system. Tightening torque brake pipe nut: 13-17 Nm proportional valve nut: 35-55 Nm.
