What is a brake drum replacement?
When getting a brake drum replacement service, the mechanic will assess the vehicle’s brake drums to confirm that a replacement is needed. The brakes need brake drums to function, as the brake drums cause the car to slow down.
Brake drums fully enclose all the rear brake components, such as the wheel cylinder, springs and clips, brake shoes, and parking brake mechanism.
If a brake drum is cracked or warped, it can severely affect your vehicle’s braking effectiveness, which can be a safety concern on the road.
How do I know if my brake drums need replacing?
If your braking effectiveness has reduced, it might be time to replace the brake drum.
Other common symptoms that may indicate the need for a brake drum service include:
The vehicle is pulling to one side
Vibration, grinding, or scraping noise
If a brake shoe requires replacement
Loss of parking brake function
Spongy or soft brake pedal
How often should brake drums be replaced?
Brake drums are only used when your car’s brakes are applied, which means they’re durable and built to last. Despite generating slightly more friction than disc brakes, on average, brake drums should be replaced every 150,000 to 200,000 miles. In some cases, the brake drums may wear out sooner due to worn-out internal components that add strain on the drum.
Most often, brake drums must be replaced in pairs, even if only one is worn or broken. During a replacement, other brake system components will be inspected to ensure the drum hasn’t damaged anything else.
Can I replace my brake drums myself?
As with many other brake system components, if you’re car-savvy and like a DIY challenge, you can replace your brake drums at home with a few simple tools. However, if you’re not familiar with the brake system and don’t have much automotive knowledge, it’s best to let a professional do it.
