Like most other car parts, brake lines can deteriorate in time, needing a brake line repair. If your car brakes are to work normally and keep you safe while you are driving, you need to inspect your brake lines and related equipment at least once each year and change bad pipes or tubing. To repair your car’s brake lines, follow these under listed 6 steps.
Ø Empty Fluid from Brake Lines
Loosening any kind of connections on your brake lines will most often result in loss of brake fluid. To stop this, remove fluid out of the master cylinder with a good siphon so to avoid.
Ø Keep Excessive Air from Entering Brake Lines
Take measures to keep excessive air from entering the brake lines. To achieve this, clamp the hose with hose clamps or with self-locking pliers. You will equally need to clean off loose dirt around your pipe openings that might enter the hoses when they are disconnected or reconnected.
Ø Take out the Brake Lines
Most often, two union nuts are used to connect brake lines and break line hoses. To remove a brake line, hold one of these nuts in position with a wrench while you use the second wrench to loosen the nut at the opposite end of the pipe. To keep from stripping the nuts’ threads, make use of a flare nut wrenches. When you have both nuts loose, pull the retaining clips that attach the fittings to the pipe.
Ø Take out the Brake Line Hose
At one end of the hose you’ll see a banjo bolt that links the hose to the brake caliper. Disconnect this bolt and keep it where you’ll find it later when you’re ready to connect your new hose and sealing washers.
Ø Replace Brake Line Pipe
When installing the new pipe, you may have to bend it. If so, be sure to make bends the same as those on the old pipe, using a pipe bender. Once you have linked the new pipe onto the retaining clips, tighten the nuts again. Check to be sure the pipes and hoses are not too close to any hot or moving car parts that they may get damaged.
Ø Bleeding the Brake System
After the working on the cars brake lines, they’ll have air in them that could make your brakes mushy and less active. To avoid this be sure to bleed the air from the lines. Refill the master cylinder with brake fluid. Find the bleeder valve on each brake caliper and remove the cap that covers the valve. Turn the valve slightly open. Attach a clear tube to the valve and place the other end into a container. Have someone depress the car’s brake pedal, which will then force air and fluid out of the brake line, past the valve, through the clear tube and into the container. When you see clean fluid flow through the clear tube, close the valve. Repeat this procedure with each of the other 3 wheels. When finished, refill the master cylinder with clean fluid.
