In the 10 years that Wendy Arriz has been a real estate agent in New York City, she’s seen some of the best, selling ultraluxe new-construction homes, as well as lower-priced properties. But she’s also seen some of the not-so-best work out there.

These cables, along with the torsion spring, counterbalance the door’s weight. With the help of these parts, the garage door can be lifted easily. However, if the garage door cables become damaged, the spring system can break. It can lead to severe injury. Therefore, replacing the damaged cable, as soon as possible, is the best idea.

However, someone who is not rightly acquainted with the garage door system should not perform this task. It can even degrade the matter. In this case, the Infinity Garage Door service comes to help you. We are reliable service providers who can solve any of your garage door problems.

When you can replace your garage door cables and bottom bracket?

You can replace your garage door cables when you are properly familiar with the system. You also need particular skills and experience regarding this mechanical task. Physical strength is also important in this matter so that you can climb the ladder or use heavy tools.

Moreover, you will need the proper tools and safety gear. This includes safety glasses, gloves, and work boots. Besides, read the instructions completely and carefully and clearly understand them.

You should wear proper clothes and avoid wearing any kind of jewelry. If you can not completely understand the instructions or lack any of the tools or safety measures, you must contact the experts. Infinity Garage Doors service has experienced professionals in this field to help you.

What are the tools you need to perform the task?

Several tools are needed to replace the garage door cable and bottom bracket. Without proper tools, this task will be a failure.

The tools you will need are:

  • A ladder
  • Two pairs of locking pliers
  • Winding bars or metal rods
  • Different types of sockets
  • Various sizes of wrenches, including 1/2, 3/8, 7/16, and 9/16


How to repair the cable and bottom bracket?

At first, check out your garage door torsion spring set up. The direction is mainly based on that. The front is mounted with a center bearing plate with attached springs. Bearing plates with cables come up from the backside of the cable drums. Only with this setup, you can follow the given directions.

If your garage system has a different type of setting, consult the professionals. Do not try these instructions, in this case. Otherwise, this can lead to grave consequences.

If you are ready with all the tools and prepared to perform the job, you may follow the given instructions.

  • At first, disconnect the garage door opener from the electric outlet.
  • The garage door opener arm connects the opener with the door. You may remove the connecting arm from the door opener.
  • Make sure the door is closed while you are doing the job. In this case, you may place clamps on the track that is situated above the middle roller.
  • Now, unwind the torsion spring or the springs. At first, place the ladder in such a way that you can keep your face from the winding cone and bars while performing this task. You may hold on one of the winding bars and insert it into the cone. Now, you can let loose the screws on the winding cones. The set screws must not be in contact with the door shaft.
  • Once it is done, enter another winding bar into the cones, fully. After that, you may lift up and remove the first bar. And then, you have to insert the winding bar into the next hole of the cone. You need to repeat the same process until all strain is removed from the spring.
  • While unwinding the spring, keep counting the amount of quarter turns you have removed from it. You will need this later while reapplying the tension. You must be concentrated on the work. Eliminate everything that can distract you, while unwinding the springs.
  • If your garage has two torsion springs, you need to unwind the second spring as well. You may need to follow the same process given above to perform this. Once all the strain is removed from the garage door, you may proceed further.
  • Now, you need to loosen the set-screws on the cable drum. Then, you should slide the cable drum away from its place. After you have loosened the drum and removed the cable, you can drop down the cable on the floor.
  • Remove the light bolt, which holds the bottom bracket to the wall, and remove the fasteners. Now, you may slide the truck and remove the bottom bracket. Remove the cable from the bracket and the door completely.
  • After that, prepare a new cable and carefully cut off the tape wrapped around it using a knife. Attach the new cable to the bottom bracket. Now, install the roller into the bracket and line the cable behind that, on the door. Install the bracket on the door and align it properly. Reinstall and tighten the fasteners. Also, reinstall the light bolt.
  • Make sure the cable is properly set and directly running from the bottom bracket. Install the cable properly in the drum’s slot. Once the cable is properly running, carefully slide the drum against the end bearing plate. You may properly tighten the set screws on the drum. Hold the drum to keep the cable tight on it and place locking pliers on the shaft. This way, the cable will be tightened on the cable drum.

Mastering the Art of Replacing Garage Door Cables and Bottom Brackets

Become an expert on replacing garage door cables and bottom brackets with Infinity Garage Door’s in-depth guide. Ensure the safety and efficiency of your Las Vegas home with our professional tips and services. Contact 702-890-3611 for more information.

Maintaining a garage door is crucial for the safety and functionality of your home. Two of the most critical components in ensuring smooth and reliable operation are the garage door cables and bottom brackets. These elements bear a significant amount of tension and weight, making their integrity non-negotiable. Infinity Garage Door, a trusted service provider in Las Vegas, presents a comprehensive guide to understanding, diagnosing, and replacing these vital components.

Understanding the Role of Cables and Bottom Brackets in Garage Doors

Before diving into the replacement process, it’s essential to understand the function and importance of these parts:

  1. Garage Door Cables: These are responsible for lifting the weight of the door as it opens and ensuring it closes safely and smoothly. They are attached to the door’s bottom brackets and the drum near the top of the door.

  2. Bottom Brackets: Also known as corner brackets, these are located at the lower corners of the door and connect the cables to the door itself. They are under extreme tension and should only be adjusted or replaced by professionals.

Signs of Faulty Cables and Bottom Brackets

Recognizing the signs of wear or damage early can prevent more significant issues down the line:

  • Frayed or Broken Cables: Look for visible signs of wear, such as fraying or rust. Broken cables may cause the door to hang at an angle or not open smoothly.

  • Loose or Damaged Bottom Brackets: If these brackets are loose, misaligned, or damaged, they can affect the door’s balance and put undue stress on other parts.

Safety First: The Risks of DIY

Replacing garage door cables and bottom brackets can be dangerous due to the high tension they’re under. It’s strongly advised to contact professionals like Infinity Garage Door at 702-890-3611, especially if you’re in the Las Vegas area. Our trained technicians have the necessary tools and expertise to perform the job safely and efficiently.

For educational purposes, here’s an overview of how a professional might replace these components:

  1. Preparation:

    • Ensure the door is closed and disconnect the opener.
    • Clamp the door to the track to prevent it from springing open.
    • Release the tension in the springs.
  2. Removing Old Cables and Brackets:

    • Unhook the old cables from the brackets and drums.
    • Carefully remove the bottom brackets if they’re being replaced.
  3. Installing New Brackets and Cables:

    • Attach the new bottom brackets to the door.
    • Thread the new cables around the drums and secure them to the bottom brackets.
  4. Tensioning and Testing:

    • Restore tension to the springs.
    • Remove clamps and test the door manually before reconnecting the opener.

Professional Tips for Maintenance and Longevity

Even with new cables and brackets, regular maintenance is key:
