How to Check Brake Drums A Comprehensive Guide

Brake drums are a crucial component of your vehicle's braking system, particularly in older models and certain designs that utilize drum brakes. Regular inspections of your brake drums can help ensure your safety on the road by identifying potential issues before they become serious problems. Here’s how to effectively check your brake drums.

Understanding Brake Drums

Before diving into the inspection process, it’s essential to understand what brake drums are and how they function. Brake drums are circular metal components that house the brake shoes. When you press the brake pedal, hydraulic pressure forces the shoes against the inside of the drum, creating friction that slows down your vehicle.

Tools You’ll Need

To inspect your brake drums, you will typically need the following tools - A jack and jack stands - A lug wrench - Brake cleaner - A measuring tool (like calipers) - A flashlight

Steps to Check Brake Drums

1. Safety First Begin by parking your vehicle on a flat surface and engaging the parking brake. Ensure you have wheel chocks in place to prevent any movement. This is crucial for your safety during the inspection.

2. Remove the Wheel Use a lug wrench to loosen the lug nuts on the wheel you’ll be inspecting, then jack up the vehicle and secure it with jack stands. Once secured, remove the lug nuts and take off the wheel.

3. Visual Inspection With the wheel removed, inspect the exposed brake drum for any visible signs of wear or damage. Look for cracks, deep grooves, or rust. Also, check the brake shoes for significant wear or uneven surfaces.

4. Measure the Drum Use your calipers to measure the diameter of the drum. Compare your measurements to the specifications provided by the manufacturer. If the drum is worn beyond the allowable limits, it will need to be replaced.

5. Check for Scoring Use a flashlight to look inside the drum. Any scoring or grooves can indicate that the brakes are not functioning correctly and may require resurfacing or replacement.

6. Inspect the Brake Components While you’re in there, check the brake shoes for wear. The lining should be thick and even; if it appears thin or uneven, it may also need to be replaced. Pay attention to the springs and hardware that hold the shoes in place, ensuring they are intact.

7. Reassemble the Brake Assembly Once you’ve completed your inspection and addressed any issues, reassemble the brake components and replace the wheel. Secure the lug nuts and lower the vehicle.

8. Perform a Test Drive After completing your inspection, take your vehicle for a short test drive to ensure the brakes are functioning smoothly. Listen for any unusual noises and pay attention to how the brake feels.

Conclusion

Regularly checking your brake drums can save you from costly repairs and ensure your safety on the road. If you notice any significant wear or damage during your inspection, consult a professional mechanic to address the issue. Remember, your brakes are one of the most critical safety features in your vehicle, so never compromise on their maintenance.
