BLEEDING THE SERVICE BRAKE SYSTEM
Bleed the system with unlatched pedals separately for each wheel.
- Check the brake fluid level in the brake fluid tank. Add the missing volume with
the new brake fluid up to max. level .
- Slide the hose on the vent screw after removing the rubber plug and put the other
end of hose into the transparent reservoir partially filled with brake fluid (3).
- Press the brake pedal, loosen the vent screw maximally by 1/4 turn. Press the
brake pedal fully down and tighten the vent screw
- Release the brake pedal and repeat procedure so long until the clear brake fluid
without bubbles flows out from the hose. Check the brake fluid level in the brake
fluid tank when bleeding to avoid aerating the brake system (1). Keep the hose
end permanently under brake fluid level. Reservoir (2) needs to be kept in the
highest possible position. The brake fluid must be completely exchanged in the
whole brake circuit minimally after two years.
