Brake System Pressure, Measure

Check brake system pressure with MKM-558 or gauge.

Screw test leads to front (1) and rear (2) brake calliper - note manufacturer's instructions. In vehicles with rear drum brake: connect test lead with Adapter MKM-558-1 to wheel brake cylinder.

Pressure Test:

In the brake system build up a pressure of 50 to 100 bar and position brake pedal tensioner. Duration of test approx. 10 minutes, during which time the pressure in the brake system must not decrease.

Measure

The brake pressure for the front axle and rear axle must be identical.( ± 1 to 1.5 bar). Check the brake lines, brake hoses and brake callipers or wheel brake cylinders for leaks if the pressure difference is greater.

Inspect

Bleed brake system bleed and check for leaks - see operation "Brake System, Bleed and Check for Leaks".
