Changing drum brakes is a crucial maintenance task for vehicle owners, ensuring safety and optimal performance. While the exact time it takes to change drum brakes can vary depending on several factors, understanding the process and the time involved can help you prepare for this important task.
Understanding Drum Brakes
Drum brakes consist of a brake drum, brake shoes, and a hydraulic system that operates the brakes. They are commonly found in older vehicles and on the rear wheels of many modern cars, particularly those with lighter rear loads. When the brake pedal is pressed, hydraulic fluid moves the brake shoes against the inside of the drum, creating friction to slow down the vehicle.
Time Required for a Drum Brake Replacement
On average, a skilled mechanic can change drum brakes in about 1 to 2 hours, depending on specific circumstances. For a DIY mechanic, the process may take a bit longer, potentially 2 to 4 hours, particularly if you are unfamiliar with the procedure or lack the necessary tools. Below are the factors that can affect the time it takes to change drum brakes
1. Experience Level Skilled mechanics can quickly and efficiently change drum brakes due to their familiarity with the process. Novice individuals might struggle with disassembly, reassembly, and adjustments, resulting in longer repair times.
2. Tools and Equipment Having the right tools handy can significantly reduce the time required for the job. Essential tools include a jack, jack stands, lug wrench, and drum brake tool kit. Without proper tools, the job may take longer.
3. Condition of the Vehicle The age and condition of the vehicle can greatly impact the time required. If the brake components are corroded or stuck, extra time may be needed to remove them. Similarly, if additional parts need to be replaced, such as wheel cylinders or springs, this will extend the duration of the task.
4. Type of Drum Brake System Some vehicles may have more complex drum brake systems than others. If the brakes include features like self-adjusters or specialized hardware, the process may be more time-consuming.
5. Preparation and Cleanup The time taken for preparation, including lifting the vehicle and removing the wheel, should also be considered. Additionally, cleaning up old grease and debris after replacing the brakes can add to the total time.
Steps to Change Drum Brakes
1. Preparation Begin by securing the vehicle with jack stands and removing the wheel. Ensure that you have a clear workspace.
2. Remove the Brake Drum Depending on the design, you may need to remove retaining screws or clips. If the drums are stuck, you may need to tap them gently to loosen them.
3. Inspect Components Check the condition of the brake shoes, springs, and wheel cylinder. Replace any worn or damaged parts.
4. Install New Brake Shoes Position the new brake shoes correctly and reassemble all components, ensuring proper alignment and secure connections.
5. Reinstall Drum and Wheel Place the brake drum back, replace the wheel, and lower the vehicle to the ground. Make sure to tighten the lug nuts to the manufacturer’s specifications.
6. Test the Brakes After replacing the drum brakes, pump the brake pedal a few times to ensure proper function before taking the vehicle on the road.
Conclusion
Changing drum brakes is a task that can range from 1 to 4 hours, depending on various factors. Whether you are a seasoned mechanic or a beginner, being well-prepared and informed can make the process smoother and more efficient. Regular brake maintenance is essential for ensuring safety on the road, so don’t hesitate to seek professional help if needed. Remember, investing time in performing this task correctly can significantly enhance your vehicle’s performance and safety.
