Add brake fluid as necessary while performing the
air bleed operation, in order to prevent the tank
from running short of brake fluid.

brake pedal depressed and tighten screw and in-
stall bleeder cap.
Tightening torque (Bleeder screw):
8 N·m (0.8 kgf-m, 5.8 ft-lb)

Visually inspect bleeder screws and brake pipe
joints to make sure that there is no fluid leakage.

tance between 2 to 3 km (1 to 2 miles) to make sure
that brakes are operating properly.
