Drum brakes are a type of brake system that utilizes a rotating drum and brake shoes to slow or stop a vehicle. When the brake pedal is pressed, hydraulic pressure forces the brake shoes outward, pressing against the inside of the drum and creating friction to slow the wheel's rotation. Drum brakes are commonly found on the rear axles of many vehicles, particularly older models and some modern economy cars.
Maintaining drum brakes is essential for ensuring your vehicle's safety and performance. Properly functioning brakes are crucial for stopping your car quickly and safely, especially in emergency situations. Regular maintenance can also help extend the life of your brake components, preventing costly repairs in the future. Neglecting drum brake maintenance can lead to reduced braking power, increased stopping distances, and even complete brake failure, putting you and others at risk on the road.
A drum brake system consists of several key components that work together to slow or stop your vehicle:
Brake drum: A cylindrical metal drum that rotates with the wheel
Brake shoes: Curved metal shoes lined with friction material that press against the drum
Wheel cylinder: A hydraulic component that pushes the brake shoes outward
Brake hardware: Springs, pins, and adjusters that hold the shoes in place and control their movement
Brake backing plate: A metal plate that mounts the brake components to the axle
When you press the brake pedal, hydraulic fluid is forced into the wheel cylinder, which pushes the brake shoes outward. As the shoes contact the rotating drum, friction is generated, slowing or stopping the wheel's rotation. When you release the brake pedal, the springs pull the shoes back to their original position, allowing the wheel to rotate freely again. The brake adjuster mechanism ensures that the shoes maintain the proper distance from the drum as they wear down over time.
Brake shoes are the most common component to wear out in a drum brake system. As the friction material on the shoes wears down, braking performance diminishes, and you may notice symptoms such as:
Reduced stopping power
Increased pedal travel
Grinding noises when braking
Worn brake shoes need to be replaced to restore proper braking function.
Over time, brake drums can become scored, grooved, or warped due to heat and wear. These surface imperfections can cause:
Pulsations in the brake pedal
Reduced braking efficiency
Accelerated wear on the brake shoes
In some cases, brake drums can be resurfaced to restore a smooth braking surface, but if the damage is severe, replacement may be necessary.
Wheel cylinders are prone to leaking due to age, corrosion, or wear on the internal seals. A leaking wheel cylinder can cause:
Brake shoes to drag against the drum
Reduced braking performance
Increased wear on brake components
Leaking wheel cylinders must be replaced or rebuilt to restore proper brake function.
Brake adjusters are responsible for maintaining the proper distance between the brake shoes and the drum as the shoes wear down. If the adjusters become seized or fail to function properly:
Shoes may not contact the drum correctly
Reduced braking performance may occur
Uneven wear on brake shoes can develop
Seized adjusters must be replaced or lubricated to ensure proper brake operation.
Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. Contaminated brake fluid can cause:
Corrosion within the brake system
Damage to wheel cylinders, brake lines, and other components
Reduced braking performance by lowering the fluid's boiling point
Brake fluid should be flushed and replaced periodically to maintain the health of the brake system.
Several factors can impact the total cost of drum brake service:
The quality and cost of replacement parts can significantly influence the overall cost of drum brake service. Using high-quality, original equipment manufacturer (OEM) parts or their equivalent ensures reliable performance and longevity but may come at a higher price point. Lower-cost, aftermarket parts may save money upfront but could result in shorter service life or reduced performance.
Labor costs are a significant factor in drum brake service, as the process of disassembling, inspecting, and reassembling the brake components can be time-consuming. Labor rates vary by location and shop, with hourly rates ranging from $80 to $160 or more. The total labor cost will depend on the complexity of the repair and the time required to complete the work.
The make and model of your vehicle can affect drum brake service costs in several ways:
Some vehicles require more expensive or harder-to-find parts
Certain models may have more complex brake systems that require additional labor
