Air brakes on a semi or trailer should be inspected when the truck pulls, warns, leaks air, or has been flagged at a roadside check. Jerry's inspects brakes at the Roberts shop and can handle many roadside brake faults by mobile dispatch.
1. Unusual Sounds
Pay attention to these warning sounds:
- Squealing or squeaking when brakes are applied
- Grinding noises during braking
- Air system hissing sounds
- Clicking or rattling when brakes are used
2. Physical Warning Signs
Watch for these physical indicators:
- Brake pedal feels soft or spongy
- Vibration in the brake pedal
- Truck pulling to one side when braking
- Increased stopping distance
- Brake pedal sinking to the floor
3. Visual Inspection Points
Regular visual checks should include:
- Brake pad thickness (through wheel inspection)
- Signs of fluid leaks under the truck
- Rotor surface condition
- Air line condition and connections
- Brake chamber positioning
4. Dashboard Warning Signs
- Brake warning light illumination
- ABS system warnings
- Low air pressure warnings
- Check Engine light (if brake-related)
5. Performance Changes
Notice these performance indicators:
- Reduced braking efficiency
- Uneven braking performance
- Brake drag or grabbing
- Changes in air system recovery time
6. Time and Mileage Considerations
Regular inspections should be scheduled based on:
- Mileage intervals used by some fleets, often discussed around 15,000–20,000 miles. That is a maintenance practice, not a federal mileage rule. Follow the brake condition and your own inspection schedule.
- Operating conditions (urban vs. highway)
- Load types and weights carried
- Previous maintenance history
7. Environmental Factors
Consider these environmental impacts:
- Exposure to road salt and chemicals
- Operation in mountainous terrain
- Frequent operation in wet conditions
- Extreme temperature variations
