Initial Inspection and Diagnostic Overview

Inspection and Verification

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. Failure to follow these instructions may result in personal injury.

Caution: Do not spill brake fluid onto painted surfaces. If spilled, wipe it up immediately.

Note: Always check the fluid level in the brake master cylinder before carrying out the test procedures. If the fluid level is not at the MAX line, add DOT 3 motor vehicle brake fluid.

Note: Prior to carrying out any diagnosis, verify that the brake warning indicator is functional. Apply the parking brake. If the brake warning indicator does not illuminate, troubleshoot the warning lamp.

The primary indicators of brake system concerns are a change in the feeling through the brake pedal, the brake warning indicator, and the brake fluid level.
