BRAKE FLUID
BLEEDING
HINT:
If any work is done on the brake system or if air in the brake lines
is suspected, 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 has been disassembled or if the reservoir
becomes empty, bleed the air from the master cylinder.
(a) Disconnect the brake lines from the master cylinder.
SST 09023-00100
(b) Slowly depress the brake pedal and hold it.
(c) Block off the outlet plugs with your fingers, and release
the brake pedal.
(d) Repeat (b) and (c) 3 or 4 times.
3. CONNECT VINYL TUBE TO BRAKE CALIPER BLEED-
ER PLUG
Insert other end of the tube in a half-full container of brake fluid.
NOTICE:
Bleed air of the rear brake first. If front brake is bled first,
rear brake air cannot be bled.
4. BLEED BRAKE LINE
(a) Slowly depress the brake pedal several times.

(b) While an assistant depresses the pedal, loosen the
bleeder plug until fluid starts to run out. Then tighten the
bleeder plug.
(c) Repeat this procedure until there are no more air bubbles
in the fluid.
Bleeder plug tightening torque:
8.3 N´m (85 kgf´cm, 74 in.´lbf)
5. REPEAT PROCEDURE FOR EACH WHEEL
6. w/ VSC:
BLEED PRECHARGE PUMP
CAUTION:
When repairing the brake master cylinder or precharge
pump, bleed the precharge pump of the air.

ML- (1) terminal to the battery negative (-), and activate
the precharge pump about 20 seconds.
(e) Remove the SST from the reservoir.
(f) Connect the vinyl tube to the front brake caliper RH, and
loosen the bleeder plug.
(g) Activate the precharge pump again until there are no
more air bubbles in the fluid.
