WARNING:

Brake fluid contains polyglycol ethers and polyglycols. Avoid contact
with eyes. Wash hands thoroughly after handling. If brake fluid contacts
eyes, flush eyes with running water for 15 minutes. Get medical attention
if irritation persists. If taken internally, drink water and induce vomiting.
Get medical attention immediately.

CAUTION: Brake fluid is harmful to painted or plastic surfaces. If brake fluid is spilled

onto a painted or plastic surface, immediately wash it with water.

CAUTION: Do not allow the master cylinder to run dry during the bleeding operation.

Keep the master cylinder filled with the specified brake fluid. Never use
brake fluid that has been drained from the hydraulic system.

NOTE:

It is not necessary to do a complete brake system bleed if only the disc
brake caliper (2B120) was disconnected.

1. Connect the scan tool DCL cable adapter into the vehicle data link connector (DLC) under the dash and

follow the scan tool manuals.

2. Clean all dirt from and remove the brake master cylinder filler cap and fill the brake master cylinder

reservoir with the specified brake fluid.

WARNING:

Use of any brake fluid other than approved DOT 3 or DOT 4 will cause
permanent damage to brake components and will render the brakes
inoperative.

WARNING:

Brake fluid contains polyglycol ethers and polyglycols. Avoid contact
with eyes. Wash hands thoroughly after handling. If brake fluid contacts
eyes, flush eyes with running water for 15 minutes. Get medical attention
if irritation persists. If taken internally, drink water and induce vomiting.
Get medical attention immediately.

CAUTION: Do not allow the brake master cylinder reservoir to run dry during the

bleeding operation. Keep the brake master cylinder reservoir filled with the
specified brake fluid. Never reuse the brake fluid that has been drained
from the hydraulic system.

CAUTION: Brake fluid is harmful to painted and plastic surfaces. If brake fluid is

spilled onto a painted or plastic surface, immediately wash it with water.

NOTE:

When any part of the hydraulic system has been disconnected for repair or
installation of new components, air can get into the system and cause spongy
brake pedal action. This requires bleeding of the hydraulic system after it has
been correctly connected. The hydraulic system can be bled manually or with
pressure bleeding equipment.
