Check after removal
Checking the length of the protruding part of the rod
1. Using a hand-held vacuum pump, create a vacuum of -66.7 kPa in the brake booster (-500 mmHg.).
2. Check the length (A) protruding part of the rod.
Standard:
Length (A) stem extension: See section below «Technical data and specifications».
Checking the length of the pressure rod
Loosen the locknut (1) and adjust the length of the pressure rod (2) to standard value (IN).
Standard:
Press rod length (IN): See below distributed «Technical data and specifications».
2. Tighten the locknut to the required torque.
Check after installation
Functionality check
Press the brake pedal several times at 5-second intervals with the engine off. Then, pressing the brake pedal all the way, start the engine. Make sure that the gap between the brake pedal and the floor panel decreases.
Note. When you press the brake pedal all the way, you may feel a slight bump with a slight click. This is a normal phenomenon due to the operation of the braking system.
Leak test
- Start the engine and let it run at idle speed for about 1 minute, applying vacuum to the amplifier. Turn off the engine. Then press the brake pedal several times at 5-second intervals with normal force and release any existing vacuum. Make sure that when you press the brake pedal, the gap between the brake pedal and the floor panel gradually increases (A→B→C).
- Press the brake pedal with the engine running and turn off the engine while pressing the pedal. Hold the pedal down for about 30 seconds and make sure that the pedal travel does not change.
Note. When you press the brake pedal all the way, you may feel a slight bump with a slight click. This is a normal phenomenon and is explained by the operation of the braking system.
Adjustment after installation
After installing the brake pedal assembly on the vehicle, adjust it. See above.
