The brake fluid must always be visible in the contain-

er, because the piston in the base of the wheel-cir-
cuit reservoir must always be covered by the fluid.
The procedure must be repeated if the fluid drops
below the "min" level.

The higher the brake pressure the faster the fluid is
pumped through the system, which means that the

If necessary, use a cable tie to secure the bleed
