Glossary

Air Brake System

An air brake system uses compressed air instead of hydraulic fluid to operate the brakes on heavy-duty trucks, trailers, buses, and other commercial vehicles. The system includes an air compressor, reservoirs, valves, brake chambers, airlines, and slack adjusters that work together to provide reliable stopping power under heavy loads. Because commercial vehicles depend on properly functioning brakes for safe operation, routine inspections are essential to identify air leaks, worn components, or adjustment issues before they become serious problems. Commercial Vehicle Inspections and Heavy Duty Truck Repair include comprehensive air brake inspections and repairs to help improve safety, reduce downtime, and support compliance with commercial vehicle safety standards established by Transport Canada and Alberta Transportation.

Alternator

The alternator is an essential electrical component that generates electricity while the engine is running to recharge the battery and power systems such as lighting, sensors, engine controls, and onboard accessories. A failing alternator can cause battery drain, dim lights, warning indicators, charging problems, or even leave a commercial vehicle unable to restart. Regular charging system inspections help identify worn alternators before complete failure occurs. Battery Replacement and Heavy Duty Truck Repair include alternator testing and charging system diagnostics to maintain dependable electrical performance. Additional information about alternator operation is available from HowStuffWorks’ alternator  educational resources on automotive charging systems.

Axle Alignment

Axle alignment is the process of ensuring a truck’s axles and wheels are positioned according to manufacturer specifications to promote proper handling, tire wear, and drivetrain performance. Poor alignment may cause uneven tire wear, steering pull, increased rolling resistance, vibration, and reduced fuel efficiency. Commercial trucks operating with misaligned axles can also experience additional stress on suspension and steering components. Heavy Duty Truck Repair, Medium Duty Repairs, and Fleet Services & Preventative Maintenance include alignment inspections that help maximize tire life, improve vehicle stability, reduce operating costs, and extend the lifespan of suspension and drivetrain components.

Battery Replacement

Battery replacement involves removing a worn or failed battery and installing a properly rated replacement that meets the vehicle’s electrical requirements. Before replacing the battery, technicians typically inspect the charging system, battery cables, terminals, and alternator to ensure another electrical issue is not causing repeated battery failures. Commercial trucks rely heavily on dependable battery performance for engine starting and electronic systems, making routine battery testing an important part of preventative maintenance. Battery Replacement services help reduce unexpected breakdowns while Fleet Services & Preventative Maintenance programs include scheduled battery inspections to improve long-term reliability throughout the year.

Brake Pads

Brake pads are friction components that press against brake rotors to slow or stop a vehicle safely. Over time, brake pads gradually wear due to normal braking and eventually require replacement to maintain effective stopping performance. Worn brake pads may cause squealing noises, reduced braking efficiency, vibration, or damage to other brake components if ignored. Routine brake inspections performed during Commercial Vehicle Inspections and Heavy Duty Truck Repair help identify worn pads before they affect safety. Replacing brake pads at recommended intervals contributes to reliable braking performance, reduces repair costs, and improves overall vehicle safety.

Cabin Air Filter

A cabin air filter removes dust, pollen, dirt, smoke, and other airborne contaminants before they enter the passenger compartment through the heating and air conditioning system. Clean cabin air improves driver comfort while helping maintain proper airflow through the HVAC system. Over time, filters become clogged, reducing airflow and increasing strain on climate control components. Replacing the cabin air filter during routine maintenance helps improve interior air quality and HVAC performance. Light Duty Services and Fleet Services & Preventative Maintenance include inspection and replacement of cabin air filters as part of comprehensive vehicle maintenance programs.

Camshaft

The camshaft is a critical engine component that controls the opening and closing of intake and exhaust valves according to precise engine timing.
