BRAKE FLUID
BLEEDING
HINT:
If any work is done on the brake system or if air is suspected in
the brake lines, bleed the air from the system.
NOTICE:
Do not let brake fluid remain on a painted surface. Wash it
off immediately.
1. FILL BRAKE RESERVOIR WITH BRAKE FLUID
Check the fluid level in the reservoir after bleeding each wheel.
Add fluid, if necessary.
Fluid: SAE J1703 or FMVSS No. 116 DOT3
2. BLEED MASTER CYLINDER
HINT:
If the master cylinder was disassembled or if the reservoir be-
comes empty, bleed the air from the master cylinder.
(a) Disconnect the brake lines from the master cylinder.
SST 09751±36011
(b) Slowly depress the brake pedal and hold it.
(c) Block off the outlet plug with your finger, and release the
brake pedal.
(d) Repeat (b) and (c) 3 or 4 times.
3. BLEED BRAKE LINE
(a) Connect the vinyl tube to the caliper.
(b) Depress the brake pedal several times, then loosen the
bleeder plug with the pedal held down.
(c) At the point when fluid stops coming out, tighten the
bleeder plug, then release the brake pedal.
Torque: 11 N´m (110 kgf´cm, 8 ft´lbf)
(d) Repeat (b) and (c) until all the air in the fluid has been bled
out.

(e) Repeat the procedure on the previous page to bleed the
air out of brake line for each wheel.
4. CHECK FLUID LEVEL IN RESERVOIR
Check the fluid level and add fluid if necessary.
Fluid: SAE J1703 or FMVSS No. 116 DOT3

REMOVAL
1. DRAW OUT FLUID WITH SYRINGE
NOTICE:
Wash the brake fluid off immediately if it comes into con-
tact with any painted surface.
2. DISCONNECT LEVEL WARNING SWITCH CONNEC-
TOR
3. DISCONNECT 2 MASTER CYLINDER PRESSURE

4. DISCONNECT WIRE HARNESS
Using a clip remover, disconnect the wire harness from the wire
harness bracket.
5. DISCONNECT BRAKE LINES
Using SST, disconnect the 2 brake lines from the master cylin-
der.
SST 09023±38201
Torque: 19.5 N´m (195 kgf´cm, 14 ft´lbf)
6. REMOVE MASTER CYLINDER
(a) Remove the 2 nuts and wire harness bracket.
Torque: 25 N´m (250 kgf´cm, 18 ft´lbf)
(b) Pull out the master cylinder from the brake booster.

INSTALLATION
Installation is in the reverse order of removal (See page BR±16).
HINT:

After installation, fill the brake reservoir with brake fluid and bleed brake system (See page BR±4).

Check for leaks.
NOTICE:
In case of replacing the master cylinder assembly or master cylinder pressure sensor, perform the
zero point calibration of the steering angle, master cylinder pressure, yawrate and deceleration sen-
sors (See page DI±897).
