Bleeding brake system


This basic setting is used when bleeding the anti-lock brake system (ABS). This is only necessary when one of the chambers in the brake fluid reservoir has been empty or when changing parts or brake fluid.

Note:

When bleeding air or changing brake fluid, approx. 2 litres of brake fluid is needed.

Bleeding is performed in a sequence with several steps to be done by the user. Manual bleeding shall be done before this function.

The function "Bleeding modulator" should be done before other bleeding. This should be run until air bubbles stop rising up in the brake fluid reservoir.
