Flow of Diagnosis

1. When a low brake pedal or the feel of a bottomed-out condition exists, check for brake pedal reserve. Refer to Procedures.
2. Check the fluid level. If the fluid level is below the MAX line in the brake master cylinder reservoir, add the required amount of the specified fluid.
3. Verify the parking brake control stroke is five to seven notches when pulled with a force of 98 N (22 lbs). If not, refer to Parking Brake - Adjustments.
4. When in the brake master cylinder area, check the brake tubes and brake master cylinder mounting. The brake tubes and attaching nuts must be tight. The brake tube fittings must not show any signs of leakage.
5. Inspect the brake tubes and hoses for cracks, scars, swelling or other damage and replace if necessary.
6. Inspect the brake tubes under the vehicle for damage and proper routing.
7. Check the hoses connecting the brake tubes to the front or rear disc brake calipers for any signs of damage, cracking or softening. The hose fittings must be tight without signs of leakage.
