Air Bleeding of Brake SystemS7RS0B4106006
CAUTION!
Brake fluid is extremely damaging to paint. If
fluid should accidentally touch painted
surface, immediately wipe fluid from paint
and clean painted surface.
Bleeding operation is necessary to remove air whenever
it entered hydraulic brake system.
Hydraulic lines of brake system are based on the
diagonal split system. When a brake pipe or hose was
disconnected at the wheel, bleeding operation must be
performed at both ends of the line of the removed pipe or
hose. When any joint part of the master cylinder of other
joint part between the master cylinder and each brake
(wheel) was removed, the hydraulic brake system must
be bled at all 4 wheel brakes.
NOTE
Perform bleeding operation starting with rear
brake caliper farthest from master cylinder
and then at front caliper of the same brake
line. Do the same on the other brake line.
1) Fill master cylinder rese rvoir with brake fluid and
keep at least one-half full of fluid during bleeding
operation.
Brake fluid
: Refer to reservoir cap (1) 2) Remove bleeder plug cap. Attach a vinyl tube (1) to
bleeder plug, and insert the other end into container
(2).
3) Depress brake pedal several times, and then while holding it depressed, loosen bleeder plug about one-
third to one-half turn.
4) When fluid pressure in cy linder is almost depleted,
retighten bleeder plug.
5) Repeat this operation until there are no more air bubbles in hydraulic line.
6) When bubbles stop, depress and hold brake pedal and tighten bleeder plug referring to “Front Disc
Brake Components in Section 4B” and “Rear Disc
Brake Components in Section 4C”.

7) Then attach bleeder plug cap.
8) After completing bleeding operation, apply fluid pressure to pipe line and check for leakage.
9) Replenish fluid into reserv oir up to specified level.
10) Check brake pedal for sponginess. If found spongy, repeat entire procedure of bleeding.

“Front Brake Hose / Pipe Construction”
CAUTION!
Do not allow brake fluid to get on painted
surfaces. Painted surfaces will be damaged
by brake fluid, flush it with water immediately
if any fluid is spilled.
Removal
1) Raise and support vehicle properly. Remove tire and wheel.
NOTE
This operation is not necessary when
removing pipes connecting master cylinder.
2) Clean dirt and foreign mate rial from both flexible
hose end and pipe end fittings.
3) Drain brake fluid in reservoir.
4) Remove brake flexible hose or pipe.
Installation
Reverse brake flexible hose removal procedure, noting
the following.
• Make sure that steering wh eel is in straight-forward
position and flexible hose has not twist or kink.
• Check to make sure that flexible hose doesn’t contact any part of suspension, both in extreme right and
extreme left turn conditions. If it does at any point,
remove and correct. Fill and maintain brake fluid level
in reservoir.
• Bleed brake system. Refer to “Air Bleeding of Brake System”.
• Perform brake test and check installed part for fluid leakage.
