How to inspect and replace flexible brake hoses for Chevrolet Blazer,S10,GMC Jimmy and 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.

Q: How to inspect and replace flexible brake hoses for Chevrolet Blazer,S10,GMC Jimmy and 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.
