What You Need to Know About Bleeding Your Brakes When Changing Pads

When changing the brake pads on your vehicle, it is important to properly bleed the brakes to ensure that the brakes are working correctly. Bleeding the brakes is a process that removes air from the brake lines and ensures that the brakes are functioning properly.

The first step in bleeding the brakes is to locate the brake fluid reservoir. This is usually located near the master cylinder, which is typically located near the firewall of the vehicle. Once the reservoir is located, the cap should be removed and the fluid level should be checked. If the fluid level is low, it should be topped off with the appropriate type of brake fluid.

Next, the brake lines should be inspected for any signs of damage or corrosion. If any damage is found, the lines should be replaced. Once the lines have been inspected, the bleeder screws should be located. These are typically located on the back of the calipers.

Once the bleeder screws have been located, the brake pedal should be depressed and held down. This will allow the air to escape from the brake lines. The bleeder screws should then be opened one at a time, starting with the furthest away from the master cylinder. As each bleeder screw is opened, the brake pedal should be released and then depressed again. This process should be repeated until all of the air has been removed from the brake lines.

Once all of the air has been removed from the brake lines, the bleeder screws should be closed and the brake fluid reservoir should be topped off. The brake pads should then be installed and the brakes should be tested to ensure that they are functioning properly.

Bleeding the brakes is an important step in changing the brake pads on your vehicle. It is important to ensure that all of the air has been removed from the brake lines and that the brakes are functioning properly. If done correctly, this process will ensure that your brakes are working correctly and that your vehicle is safe to drive.
