GM 30023506 HOSE

With jacks holding your vehicle safely in the air, check out these rubber brake hoses at least twice a year for cracks, wearing, leaks, bubbles, and other problems as you lift and support the car. If any hose shows these conditions, replace it. The first step in replacing the brake hoses at the front and back is to free the brake line from the clamp that holds it to the frame bracket, but keep the line itself straight so it doesn't fold. Lift the U-clip from the frame bracket's fitting at the female end, then pull the hose off. When fixing a brake hose at the front caliper, take off the union bolt at that end, then separate the hose while swapping in both copper sealing washers. Unscrew the rear brake hose from the axle just like you did at the other end. Before joining the front hose to the caliper, go through the bracket with the correct end of the hose. Connect the hose to the caliper by threading the union bolt through and using both copper washers. Make sure the locating lug locks into place, then tighten to the required force. Place the hose female fitting into the frame bracket without twisting it, then attach the clip right behind. Loop the brake line into the hose fitting, making sure you straighten any bends in the hose. Also check if the hose touches the suspension when you move the wheels fully left and right. If contact occurs, correct the installation. To fix brake lines, always use steel replacements that don't use copper tubing. You can buy brake lines at car parts stores, already with flared tube ends and the correct connections already attached. Double-check that the pipe has both correct support and enough space to run without interfering with other parts that move or get hot. Before testing the brakes, top up the master cylinder fluid level, then add new fluid if needed. Bleed the braking system, then thoroughly check that your brakes are working correctly.
