Check the brake booster function if the pedal effort is unusually high to achieve adequate braking effect.

  • With the engine off, press the brake pedal down firmly at least 5 times, then start the engine with the pedal depressed. The brake pedal should now noticeably give way under foot. The brake system is then in order.

  • Otherwise, disconnect the vacuum hose from the brake booster and start the engine. Place a finger on the end of the vacuum hose to check whether vacuum is generated with the engine running.

  • If there is no vacuum: check the vacuum hose for leaks and damage, and replace if necessary. Tighten all clamps securely.

  • Diesel engine: disconnect the vacuum hose from the vacuum pump and check with a finger whether vacuum is present at the hose connection.
