The drums were rusty at the hub, which made the problem worse. Also, the car’s manual was of no help as nothing was mentioned there regarding the size of the bolt.

After much research and effort, I removed brake drums by using an M8 x 1.25 bolt. If you, too, are stuck and need some assistance in removing the brake drums, read further.

How Do You Remove Brake Drum Bolts?

Removing a brake drum can be a risky affair if the brake drums are stuck due to some reason. The reason can be a rusty hub or a lip on the backside, catching up on the pads. If you cannot rotate the drum, the pads are either by rust, a stuck parking brake, or a stuck wheel cylinder. 

How to Remove a Rusted Bolt?

It is common for the brake drum bolts to get rusty as they stay outdoors for their entire life. All you will need to remove the bolt is:

  • Hammer
  • Box-end wrench
  • Penetrating oil
  • Locking pliers
  • Socket wrench

Step 1: Spray a good amount of penetrating oil on the rusted bolts. Make sure you dampen the entire area using good-quality oil. You can use a spray can for this purpose.

Step 2: Let the sprayed area absorb the oil for a few minutes. If need be, spray one more coat of oil. 

Step 3: Now, with the help of a socket wrench, try to loosen the bolt.

Step 4: if the bolt is not moving or is very tight, use a hammer to tap lightly on the bolt’s head. While tapping with a hammer, make sure you don’t damage the hex head. If the bolt is slipping, apply another coat of oil and let it sit for a few more minutes.

Step 5: Now grab a locking plier, adjust the tension and grab the bolt firmly to loosen the head and remove the bolt from the brake drum.

How Do You Remove A Brake Drum From A Toyota?

In a Toyota, you will find the brake drums located with the rear wheels. If you follow these steps diligently, you can easily remove a brake drum from Toyota models.

Step 1: Loosen the wheel’s nuts and, by using a jack stand, raise the rear end of the car.

Step 2: lock the car’s front wheels to prevent any movement of the car.

Do They Make A Brake Drum Puller?

Yes, today, many companies are making brake drum pullers. Sometimes it can become very difficult to take out drum brakes from your car. You may need a brake puller to pull it out. 

A brake puller is exactly what it sounds like: a tool which removes the drum from the brake shoes using leverage. It is more effective than any other manual measure. You might need it if your vehicle is too old or your brakes are too far gone. 

A longish bolt attached in the puller’s center gives it the leverage required to pull the drum. If you turn this bolt, the puller will start pulling the drum from the assembly. 

If you seldom work on your car, you can easily rent one from the local tool supplier. If you love old cars and working on them, you can buy one at a local shop or online

When Should Brake Drums Be Replaced?

Brake drums are one of the most sturdy parts of the car and are meant to last long. They are used only when you apply brakes. Your car’s drum brakes can last 200,000 miles. Isn’t this great? 

But in some cases, the brake drums might require an early replacement. This can be only when the other braking system parts are not working well or the driver is an amateur. If the drums get smaller, you will know that it’s time you change it. 

But keep in mind if you are doing this on your own, you should change both the drums in the hub and not one. Also, make sure you check other parts of the braking system, such as the disc, brake pads, metal tab, etc.
