Brake & Suspension Repair in Davenport, Florida

Air brakes use compressed air to apply braking force instead of hydraulic fluid. When you press the brake pedal, air pressure pushes against brake chambers that activate the brake shoes or pads. Air brakes are required on most commercial trucks because they are more reliable for heavy loads and provide a fail-safe design — if air pressure is lost, the brakes automatically engage through spring pressure rather than releasing.

Brake lifespan varies based on driving conditions, load weight, and terrain. On average, commercial truck brake pads or shoes last between 25,000 and 65,000 miles. Trucks that operate in hilly areas, carry maximum loads, or make frequent stops will need brake service more often. We recommend inspecting your brakes at every scheduled maintenance visit to catch wear before it becomes a safety issue.

Yes. Heavy-duty trucks require alignment equipment rated for their weight and axle configurations. Standard passenger-vehicle alignment racks cannot accommodate the size and weight of commercial trucks. At R&J Truck Repair, we have the proper equipment to perform accurate alignments on heavy-duty vehicles, ensuring your truck tracks straight and your tires wear evenly.

Signs that your shocks or struts are worn include a bouncy or rough ride, excessive body roll in turns, the truck nose-diving when braking, fluid leaking from the shock body, and uneven tire wear. Most shocks and struts should be inspected around 50,000 miles and replaced when they no longer provide adequate damping.

The Department of Transportation requires commercial vehicles to maintain properly functioning braking systems at all times. During a DOT inspection, brake components are checked for adequate lining thickness, proper adjustment, air leaks in the air brake system, and overall condition. Brake violations are among the most common reasons for being placed out of service. We can inspect and repair your truck's brakes to ensure full DOT compliance.
