How to inspect and replace flexible brake hoses on GMC Sonoma?

About every six months, it is important to inspect the flexible hoses that connect the steel brake lines with the front and rear brake assemblies for any cracks, chafing, leaks, blisters, or other damage. This inspection should be done with the vehicle raised and securely placed on jackstands, using a light and mirror for a thorough check. If any of the above defects are found, the hose should be replaced with a new one. To replace the hose, start by cleaning any dirt away from the ends of the hose and disconnecting the brake line from the hose fitting, being careful not to bend the frame bracket or line. If necessary, soak the connections with penetrating oil. Remove the U-clip from the female fitting at the bracket and remove the hose from the bracket. Disconnect the hose from the caliper, discarding the copper washers on either side of the fitting. Attach the new brake hose to the caliper using new copper washers. Pass the female fitting through the frame or frame bracket, installing it with the least amount of twist in the hose. Install the U-clip in the female fitting at the frame bracket. Attach the brake line to the hose fitting using a back-up wrench on the fitting. Carefully check to ensure that the suspension or steering components do not make contact with the hose, and have an assistant push down on the vehicle and turn the steering wheel lock-to-lock during inspection. Afterward, bleed the brake system. When replacing brake lines, always use the correct parts and avoid using copper tubing. Purchase steel brake lines, preferably prefabricated ones with the tube ends already flared and fittings installed. Ensure that the new line is well supported in the brackets and has plenty of clearance between moving or hot components. After installation, check the master cylinder fluid level and add fluid as necessary. Finally, bleed the brake system and test the brakes carefully before placing the vehicle into normal operation.

GMC Sonoma Brake Line

The Brake Line in GMC Sonoma vehicles can be described as the line responsible for transporting brake fluid from the master cylinder to the brake caliper pistons so that hydraulic braking works. The metal brake lines are vulnerable to factors such as corrosion and mechanical impacts leading to flow of the brake fluid and low pressure. The brake hoses can also wear out physically and on the inside which can have a serious impact on the vehicle's breaks. Luckily, there are prebent brake line kits and direct replacement brake hoses where necessary and these are both random and corrosion free. Retracting the brake hoses with high quality braided stainless steel lines can help to address the complaint substantially for the performance roads uses.

Each OEM GMC Sonoma Brake Line we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

Q: How to inspect and replace flexible brake hoses on GMC Sonoma?
A: About every six months, it is important to inspect the flexible hoses that connect the steel brake lines with the front and rear brake assemblies for any cracks, chafing, leaks, blisters, or other damage. This inspection should be done with the vehicle raised and securely placed on jackstands, using a light and mirror for a thorough check. If any of the above defects are found, the hose should be replaced with a new one. To replace the hose, start by cleaning any dirt away from the ends of the hose and disconnecting the brake line from the hose fitting, being careful not to bend the frame bracket or line. If necessary, soak the connections with penetrating oil. Remove the U-clip from the female fitting at the bracket and remove the hose from the bracket. Disconnect the hose from the caliper, discarding the copper washers on either side of the fitting. Attach the new brake hose to the caliper using new copper washers. Pass the female fitting through the frame or frame bracket, installing it with the least amount of twist in the hose. Install the U-clip in the female fitting at the frame bracket. Attach the brake line to the hose fitting using a back-up wrench on the fitting. Carefully check to ensure that the suspension or steering components do not make contact with the hose, and have an assistant push down on the vehicle and turn the steering wheel lock-to-lock during inspection. Afterward, bleed the brake system. When replacing brake lines, always use the correct parts and avoid using copper tubing. Purchase steel brake lines, preferably prefabricated ones with the tube ends already flared and fittings installed. Ensure that the new line is well supported in the brackets and has plenty of clearance between moving or hot components. After installation, check the master cylinder fluid level and add fluid as necessary. Finally, bleed the brake system and test the brakes carefully before placing the vehicle into normal operation.
