Air bleeder screws
<Front> <Rear>
3. BLEEDING <EVOLUTION-V>
Connect a vinyl tube to the outer end of the air bleeder screw
to bleed the circuit of air. Then, connect the vinyl tube to
the inner end and bleed the circuit of air. Except for these,
the conventional procedures shall be followed. After the circuit
has been bled of air, tighten both air bleeder screws to the
specified torque.
4. DISC BRAKE PAD CHECK AND
REPLACEMENT <EVOLUTION-IV>
4-1 FRONT BRAKE
Use the same procedure as that for the 2-pot type disc brake.
4-2 REAR BRAKE
The conventional procedures apply except for the following
standard value for the brake pad thickness.
Standard value (brake pad thickness): 10.0 mm
Limit: 2.0 mm
5. DISC BRAKE PAD CHECK AND
REPLACEMENT <EVOLUTION-V>
NOTE
The wear indicator contacts the brake disc to squeak when
the pad thickness becomes about 2 mm, warning the driver
that the pad needs replacement.
(1) Visually check for the brake pad thickness through the
inspection hole in the caliper body.
Clips
Standard value: 10.0 mm
Limit: 2.0 mm
(2) If the brake pad thickness is less than the limit, follow
steps (3) and onward to replace the brake pads on both
sides with new ones as a set.
(3) Remove clips from the pins.
(4) Holding the cross spring with one hand, pull the pin out
of the caliper.
