Brake pedal adjustment

Checking and adjusting the height of the brake pedal

Check brake pedal height (pic. 6.10).

Height of the brake pedal from the partition of the engine compartment:

• for left-hand drive: manual gearbox - 148.1–158.1 mm;
• multimodal MCP - 149.9–159.9 mm.

Adjust the brake pedal height.

Remove the lower finishing overlay of the panel of devices.

Disconnect the connector from the brake light switch.

Remove the brake light switch assembly.

Loosen pusher locknut.

Adjust the height of the brake pedal position by turning the booster pushrod.

Tighten the pusher locknut.

Tightening torque: 22 Nm.




Insert the brake light switch into the bushing until it lightly touches the brake pedal (pic. 6.11).

Note. Do not press the brake pedal.

Finally install the brake light switch by turning it a quarter of a turn clockwise.

Tightening torque: 1.5 Nm or less.

Connect the connector to the brake light switch assembly.

Check the brake light switch assembly clearance.

Stoplight switch gap: 1.5–2.5 mm.

Checking the free play of the brake pedal

Shut off the engine and press the brake pedal several times until the vacuum in the amplifier disappears completely.



Gently depress the brake pedal until there is resistance. Measure the distance as shown in figure 6.12.

Pedal free play: 1.0-6.0 mm.

If the free play deviates from the allowable values, proceed to the next step.

Check the brake light switch clearance.

Stoplight switch gap: 1.5–2.5 mm.

If the gap corresponds to the nominal value, the fault should be sought in the brake system.

In case of deviation from the permissible values, adjust the gap of the brake light switch.

Checking the residual travel of the brake pedal

Release the parking brake.




With the engine running, press the brake pedal and measure the remaining pedal travel as shown in Figure 6.13.

Residual travel of the brake pedal from the partition of the engine compartment when pressed with a force of 490 N: more than 50 mm.

If the residual stroke deviates from the permissible values, the fault should be sought in the brake system.
