1. What Are Brake Drums?


Brake drums and drum brakes might sound similar, but they are different. The brake drum is a component of the drum brake, and a drum brake is a type of braking mechanism. The brake drum is a cylindrical component attached to the wheel of the vehicle and rotates with it. It consists of shoes or pads that are pushed by the hydraulic wheel cylinders against the rotating drum to stop the vehicle.

2. What Type Of Brake Drum Should I Choose?

2.1 Cast Iron Brake Drums

2.1 Cast Iron Brake Drums

Brake drums are mostly made of solid cast iron because it is resistant to wear and has high heat conductivity. Cast iron brake drums are strong enough to withstand high braking forces and are resistant to distortion and warping. 

2.2 Aluminium Brake Drums

2.2 Aluminium Brake Drums

Aluminum brake drums are lighter and run cooler than cast iron brake drums. Aluminum brake drums consist of an aluminum casting with a cast-iron liner as a braking surface. This makes the brake drum assembly lighter and allows better heat transfer to the atmosphere.

3. What Are The Factors I Should Consider Before Buying A Brake Drum?

You should be sure that you are getting the best brake drum for the money you spend because a good quality brake drum can enhance the safety of you and others on the road. Since the brake drum is exposed to a lot of heat and friction, you should always choose a good combination of heat dissipation and durability. Few things to keep in mind before purchasing a brake drum are listed below.


3.1 Material

Brake drums are generally made of cast-iron. They are also made from aluminum with a steel or iron liner that offers good heat dissipation and performance. Brake drums are also provided with cooling fins or ribs that keep the drum cool and reduce brake fade. Always check your manual for the type of brake drum used on your vehicle. Most vehicles are equipped with cast iron brake drums, although you can choose aluminum brake drums for your vehicle if you want to make your vehicle more performance-oriented because they are very light compared to cast iron brake drums. 


3.2 Balance

Balanced brake drums and even-weight distribution are vital for the proper functioning of the braking system. Imbalanced brake drums can severely damage the suspension and other components. To check whether a brake drum is balanced or not, look for weights attached to the brake drum on the sides. Not all brake drums are balanced by adding weights, because some are balanced by machining. So, if you can't find weights on the drum, there is nothing to worry about but always check the product description for the same.


3.3 Warranty

Different brands offer varying warranties and you can choose the part according to the brand and the warranty they offer on their parts. Some of them come with a few years and some with a lifetime warranty so you can balance your budget with a warranty that suits your needs.


3.4 Compatibility

Finding the right fit brake drum for your vehicle is very important. Therefore, it is important to consult the vehicle repair manual or your mechanic to ensure you are getting a part compatible with your vehicle. Check the number of bolts, bolt pattern, and diameter of the drum before purchasing. Or you can simply enter the correct year, make, and model of the vehicle on the PartsAvatar website to find the perfect fitment brake drum.

6. What Are The Symptoms That My Brake Drum Is Bad?


Brake drums undergo a lot of friction and heat, and they can eventually wear out. This can lead to poor braking and affect the overall safety of the vehicle. Therefore, it is important to keep an eye on the following symptoms of a failing brake drum. 

A. Brake Pedal Vibrations


A worn-out brake drum can lead to vibrations, shaking, and trembling as you step on the brake pedal. If you witness any unusual vibration in the pedal, then it could be a worn-out brake drum.

B. Loose Parking Brake


Another telltale sign of a failing brake drum is a poor parking brake. Parking brakes use brake shoes that are squeezed against the brake drum to hold the vehicle in its place. A worn-out brake drum will cause the parking brake to slip and won't be able to keep the car parked securely. 

C. Brake Noise

Worn out brake drums can also lead to unusual sounds while operating the brakes. Brake drums are poor in absorbing heat generated from braking. This leads to heat buildup and causes scraping sounds when the shoes push against the rotating drum. 

7. FAQ’s

Q. How long do the brake drums last?

The brake drums of a vehicle can last for about 300,000 kilometers. But they can wear out soon due to other factors like driving styles, external conditions, vehicle type, etc. The brake drums of the vehicle are usually replaced in pairs for better performance. 


Q. Do the brake drums need to be turned?

Brake drums have a smooth surface that increases the brake life and provides optimum braking power. The surface can get rough over prolonged usage and can be resurfaced to a good condition.


Q. How to check if the brake drum is out of round?

Excessive noise or shudder while applying brakes can be a sign of out-of-round brake drums. Out-of-round brake drums can also be identified by dark spots or uneven surfaces on the brake lining surface. The uneven braking surface can be repaired by machining until it's smooth again.
