5G-6 AIR BRAKES

External Conditions That Affect Brake Performance

1. Tires—Tires with unequal contact and grip on the road will cause unequal braking.

The inflation and tread pattern of the right and left tires must be about equal.

2. Vehicle Loading—When the vehicle has unequal loading, the most heavily loaded

wheels require more braking force than the others.

3. Front Wheel Bearings—Loose wheel bearings permit the rotor to tilt and have

spotty contact with the linings. This causes erratic braking.

4. Front End Alignment—Misalignment of the front end, particularly camber and

caster, causes the brakes to pull to one side.

SYSTEM TESTS

Inspect

1. Air lines and tubing for kinks, twists, or dents.

2. Hoses for wear, drying, or overheating.

• The hoses should not rub against anything or touch anything with sharp edges.

3. Tubing clamps and clips.

• Tubes should be firmly held in place and not sag or vibrate.

4. Nylon lines to be sure they are away from extreme heat sources.

5. Air reservoir brackets, straps, and hanger bolts. Tighten if necessary.

6. Air connections. Tighten if necessary.
