Bleeding brake system
Procedure for bleeding
1st. Step: Bleed brakes in the normal way (in combination with bleeding device at the brake fluid reservoir and 2.0 bar pressure) (primary circuit).
2nd. Step: In addition, use the Piwis Tester to bleed the brakes (secondary circuit). Only necessary if the hydraulic unit has been replaced and, after
bleeding in the normal way (primary circuit), the brake pedal travel is excessive.
1. Step: Bleeding (primary circuit)
Information
^
Always bleed both bleeder valves on brake caliper!
^
Bleed the outer bleeder valve first!
Information

If the pedal travel is too long or the pedal feels too soft when applied, carry out bleeding again. Operate (pump) the brake pedal at the same time.
A second person is required for this.
