Adjust gap.
After working on the brake system.

To do this, depress the brake pedal firmly several times.
Depress brake pedal firmly and hold down with a constant force.
The pressure must be maintained without it being possible to depress the brake pedal further.

If the brake pedal drops under constant pressure.

↓

Establish the cause for pressure loss and replace defective components of the brake system.
Start engine and run at idle speed.
Depress brake pedal firmly and hold down with a constant force.
The high boost provided by the brake booster with the engine running causes the brake pedal to slowly yield further after a brief period.

This is design related and it does not mean that the brake system has a pressure loss.
Check whether the pressure built up in the brake system drops.
If the brake pedal drops under constant pressure.

↓

Check all hydraulic hose connections, all connection fittings and all hydraulic components of the brake system for leaks.

In the event of leakage

↓

Repair or replace affected hose connections, connection fittings or hydraulic components.

If no leakage can be found.

↓

Establish the cause for internal pressure loss and replace defective components of the brake system.
Switch off engine.
