Figure 14.8. Connect a pressure gauge to the inlet and outlet side of the brake booster valve
2. Bleed the brake line.
3. Slowly press the brake pedal and observe whether the values shown correspond to the nominal ones. The outlet pressure should decrease in relation to the inlet pressure (inflection point) (Figure 14.9). Nominal value: hatchback - 2.45±0.25, sedan - 2.94±0.25.
Figure 14.9. Slowly press the brake pedal and observe whether the values shown correspond to the nominal parameters. The outlet pressure should decrease in relation to the inlet pressure (inflection point)
4. Check that the outlet pressure is appropriate when the inlet pressure is as required.
The difference in outlet pressure between the left and right brake pipes: 0.39 MPa.
If the values obtained during measurements do not correspond to the given parameters, the brake force distribution valve must be replaced.
