Learn how to replace your brake disc step by step with our comprehensive guide. Gather tools, remove old parts, and install new disc easily.

Gathering the Necessary Tools

Before you begin the process of changing the brake discs on your GMC Sierra, it’s important to gather all the necessary tools. This will ensure that you have everything you need to complete the task efficiently and safely. Some of the essential tools you will need include a lug wrench, a jack, jack stands, a socket and ratchet set, a C-clamp, brake cleaner, and a torque wrench.

It’s also a good idea to have a wire brush, a can of penetrating oil, and a set of gloves on hand to make the process of removing the old brake discs easier and cleaner. By gathering all of these tools before you begin, you can avoid any interruptions or delays in the middle of the process.

Additionally, make sure that you have a well-lit and well-ventilated workspace to carry out the task. This will ensure that you can see clearly and work comfortably as you replace the brake discs on your GMC Sierra.

Removing the Wheel and Caliper

When it comes to changing the brake discs on your GMC Sierra, one of the first steps is to remove the wheel and caliper. This is an important part of the process, as it allows you to access the old brake disc and replace it with a new one. To start, gather all the necessary tools including a lug wrench, jack stands, and a C-clamp. Position the jack under the truck and lift it up until the wheel is off the ground. Once the truck is secure on the jack stands, use the lug wrench to remove the lug nuts and take off the wheel.

Next, you’ll need to remove the brake caliper, which can be done by using a socket wrench to loosen the bolts that hold it in place. Once the bolts are removed, carefully lift the caliper off the old brake disc and set it aside. Be sure to support the caliper with a piece of wire or rope to prevent it from hanging and putting stress on the brake line. With the caliper out of the way, you’ll have clear access to the old brake disc.

Now that the wheel and caliper have been removed, you’re one step closer to completing the brake disc replacement on your GMC Sierra. Stay tuned for the next part of this step-by-step guide, where we’ll cover the process of taking out the old brake disc and installing a new one.

Taking Out the Old Brake Disc

Before you begin the process of taking out the old brake disc, it’s important to gather all the necessary tools you will need. This includes a lug wrench, jack, jack stand, socket wrench, and C-clamp. Having these tools on hand will make the process much smoother and efficient.

Once you have all the tools ready, the first step in removing the old brake disc is to remove the wheel and caliper. Loosen the lug nuts with the lug wrench, then use the jack to lift the vehicle off the ground. Place the jack stand under the vehicle for added support. Next, use the socket wrench to loosen and remove the caliper bolts. Carefully remove the caliper from the rotor and secure it in place to prevent damage to the brake line.

With the caliper out of the way, you can now focus on taking out the old brake disc. Inspect the rotor for any signs of damage or wear. Once the condition of the rotor has been assessed, use a screwdriver or hammer to gently tap the rotor to release it from the wheel hub. In some cases, the rotor may be stuck due to rust or corrosion, so applying penetrating oil around the wheel hub can help loosen it.

Installing the New Brake Disc

Now that you have successfully removed the old brake disc, it’s time to install the new one. Before getting started, make sure you have gathered all the necessary tools such as a lug wrench, jack stand, and a new brake disc specific to your GMC Sierra model.

With the wheel and caliper removed, you can carefully place the new brake disc onto the wheel hub. Make sure it is aligned properly with the wheel studs. The new brake disc should fit snugly onto the hub without any loose movement. It’s essential to ensure a secure fit to prevent any issues with braking performance.

Once the new brake disc is in place, you can then proceed with reassembling the caliper and wheel according to the manufacturer’s specifications. It’s important to double-check the tightness of all bolts and nuts before testing the brakes to ensure everything is securely in place. With the new brake disc properly installed, your GMC Sierra will be ready to hit the road with improved braking performance.

Reassembling the Caliper and Wheel

After successfully installing the new brake disc on your GMC Sierra, the next step is to reassemble the caliper and wheel. This is a crucial step as it ensures that the brake system is properly put back together and functions correctly. Before starting this process, make sure you have all the necessary tools at hand. You will need a ratchet, socket set, brake cleaner, and a C-clamp.

First, take the caliper that you removed earlier and carefully place it back over the new brake disc. Make sure the caliper slides back over the disc smoothly and does not get caught on any part of the brake assembly. Once the caliper is in place, take the bolts that you removed earlier and use your ratchet to secure them back in their original positions. Be sure to tighten the bolts securely to ensure the caliper is properly reattached.

With the caliper back in place, it’s time to reattach the wheel. Line up the wheel with the lugs on the brake assembly and carefully slide it onto the studs. Once the wheel is in position, use your lug nuts and a socket set to secure the wheel in place. Make sure to tighten the lug nuts in a star pattern to ensure even pressure on the wheel. Once the wheel is securely attached, lower the GMC Sierra back to the ground and remove the jack. Finally, give the brake system a test by gently pressing the brake pedal to ensure everything is functioning as it should be.
