Can Brake Drums Be Welded?

You’re driving down the road and suddenly hear a loud noise coming from your car. When you pull over to the side of the highway, you notice that one of your brake drums is loose. You could take it to a mechanic and have it repaired, but you’re not sure if that’s the best course of action. After all, can brake drums be welded?

Braking drums can occur due to a number of reasons. It might be due to normal wear and tear, or it could be the result of an accident. Regardless of the cause, the end result is the same, a loose brake drum. So, you have to decide if you’re going to take it to a mechanic or try to fix it yourself.

Here, we’re going to cover brake drum issues, and you will be presented with all the information you need to know about drum breaking. Continue reading to find out more.

Can Brake Drums Be Welded as a Repair Option?

While replacing brake drums is the most effective way to repair them, it can be expensive. As a result, many people wonder if truck brake drums can be welded as a repair option. The answer is yes, but it is important to note that welding should only be performed by a qualified technician.

Welding brake drums can help to restore their strength and durability, but it is not a permanent solution. Over time, the welds will eventually begin to break down and will need to be replaced. As such, welding should only be viewed as a temporary fix until replacement brake drums can be installed.

When Do Brake Drums Become Hot?

When you press the brake pedal, your car’s brake drums are what cause the vehicle to slow down. The drums are made of sturdy metal and are designed to withstand a lot of heat. However, if they get too hot, it can cause serious damage. There are several things that can cause brake drums to get hot.

One is extended periods of braking. If you’re constantly stopping and starting, it can put a lot of strain on the drums and cause them to overheat. Another is driving in hilly or mountainous terrain. Going downhill puts extra strain on the brakes, which can lead to overheating. Finally, hot weather can also be a factor.

If it’s particularly sunny or humid out, the heat can contribute to the problem. If your brake drums get too hot, it’s important to have them checked by a mechanic as soon as possible. Otherwise, you could be at risk for an accident.

Is It Possible To Resurface Brake Drums?

Yes, brake drums can be resurfaced. In fact, resurfacing brake drums is a relatively simple process that can be completed in just a few steps. First, the brake drum is cleaned and sanded to remove any rust or debris. Next, the surface of the brake drum is measured to ensure that it is smooth and even.

Finally, a thin layer of material is applied to the surface of the brake drum, providing a new surface for the brake pads to grip. While resurfacing brake drums does require some time and effort, it is usually less expensive than replacing them outright. As such, it is often an appealing option for those looking to extend the life of their brakes.

Is Machining Brake Drums Necessary Before Welding?

No, new brake drums do not need to be machined before welding. This is because the brake drums are machined to the correct dimensions at the factory. The only time that brake drums require machining is when they have been damaged or have become warped.

In these cases, the brake drums will have to be machined in order to ensure that they fit properly. If the brake drums are not machined properly, they may not fit correctly onto the brakes, which could cause problems.

What Is the Process of Welding Brake Drums?

While the method for welding brake drums may vary depending on the make and model of your car, there are some general steps that are typically followed:

Step 01: Remove the Brake Drums

In order to weld brake drums, the first step is to remove them from the vehicle. This can typically be done by loosening the lug nuts and then pulling the drum off of the axle. Once the drum is removed, it will need to be cleaned so that there is a smooth surface to work with. And you also need to make sure that the area around the drum is clear of any debris.

Step 02: Inspect the Brake Drums

The amount of damage to the brake drums will determine the amount of prep work necessary before welding can begin. More often than not, rear brake drums suffer the worst than their counterparts. If there is minimal damage, such as small cracks or chips, then only a slight amount of grinding will be needed to smooth out the surface.

However, if the brake drums are severely damaged, it may be necessary to use a metal cutting saw to remove any badly corroded or rusted sections. Once the brake drums have been prepared, they will be ready for welding.

Step 03: Weld the Brake Drums

The actual welding process will vary depending on the type of welder being used. However, in general, the brake drums will need to be clamped in place so that they are secure. As soon as the brake drums are in place, the welder can then begin to fill in any cracks or holes.

Make sure the welds are smooth and even in order to avoid any further damage to the brake drums. Once the welding is complete, the brake drums should be allowed to cool before they can be installed onto the car.

Step 04: Inspect the Welds

Once the welds have cooled, it is important to inspect them to make sure that they are strong and secure. If there are any weak spots in the welds, they will need to be fixed before the brake drums can be installed. Be sure to also check the surface of the brake drums to make sure that there are no sharp edges that could potentially damage the brakes.

Step 05: Install the Brake Drums

As soon as the brake drums have been inspected and repaired, they can then be installed onto the car. This is typically done by aligning the brake drums with the axle and then sliding them into place. Once the brake drums are in position, the lug nuts can be tightened to secure them.

And that’s the process of welding brake drums! As you can see, it’s not a particularly difficult job, but after welding, you have to machine the brake drums so that they are the correct size and shape. If you do not have the proper equipment to do this, it is best to leave it to a professional.


There are a few questions that are commonly asked about welding brake drums, which we will answer below.

How Long Will Brake Drums Last?

Drum brakes usually last between 150,000 and 200,000 miles, but that can vary depending on how often they’re used and the conditions they’re exposed to. Regular maintenance is important, and brake drums should be inspected regularly for wear. If they’re not properly cared for, they may need to be replaced sooner.

How Does Brake Drum Potbelly Heater Works?

A brake drum potbelly heater works by using the heat from a fire to heat up a large metal drum. The drum is filled with water, and as the fire heats up the drum, the water begins to boil. This produces steam, which is then directed through a series of pipes to the brakes. The steam helps to heat up the brake fluid, making it easier for the brakes to stop the vehicle.

In addition, the steam can help to remove any moisture from the brakes, preventing them from freezing in cold weather. Overall, a brake drum potbelly heater is an efficient way to heat up the brakes and keep them in good working condition.

Do Brake Drums Consist Of Cast Iron or Steel?

Brake drums are typically made of advantage cast iron, as it dissipates heat faster than steel and has a higher coefficient of friction. This allows for better braking performance and less wear on the brake pads. And while aluminum brake drums are available, they are typically only found on racing vehicles due to their high cost.

How Often Should Drum Brake Shoes Be Replaced?

Drum brake shoes need to be replaced approximately every 30,000 to 40,000 miles in order to ensure optimal braking performance. Over time, the brake shoes will wear down and eventually need to be replaced in order to maintain safe driving conditions.


As you can see, welding brake drums is not a difficult task, but it is important to make sure that they are properly inspected and repaired before they are installed onto the car. Be sure to follow all of the steps outlined in this article in order to ensure a safe and successful repair.
