If you want to improve your car braking performance, you will need to install stainless steel brake lines. These are installed because brake fluids tend to get rather hot and put pressure on your usual brake lines. When the brake fluids get hot and expand, they start to bulge and make the brakes feel rather soft. To prevent this from happening, many people, especially car enthusiasts and street racers, make modifications on their cars by installing stainless steel brake lines and as a way to improve vehicle safety. Regardless of what car you drive, this modification can be quite expensive. The average cost of installation is approximately $1000 to $2000. For those who do not want to spend a large amount of money but would prefer to install it themselves, the instructions are below.
Step 1 – Removing the Wheels
Place the jack stands for each wheel. Before removing the wheels, unscrew the lug nuts.
Step 2 – Removing the Rear Rubber Brake Line
Choose a rear rubber brake line to remove. Make note of the way the original brake line was placed, as this is how you will need to place the new stainless steel brake lines. Put a drip pan under the caliper and the line the brake fluid will leak. In addition, you should not get any of the brake fluid on painted surfaces as the paint will start eroding. Unscrew the 10mm bolt which holds the brake tube and the brake line together with a 10mm flare nut wrench. After this, use pliers to take off the brake line clip. Once you have removed the brake line clip, put the line into the drip pan and then put the pan underneath the brake tube. For the bottom nut, you will need to use a 17mm wrench to displace the brake line away from the caliper.
Step 3 - Install the New Rear Line
With your new, clean stainless steel brake line, use a 13mm wrench to attach it to the caliper. You may need to torque it up to 17 ft-lb. Move the brake line at the rear of rear sway bar before putting it through the holder and attaching the clip. Use a 10mm wrench and screw it so that it is tight but not so tight that it is too stiff. You may need to add more brake fluids to the reservoir, so check that and add more if necessary.
Step 4 – Removing the Front Rubber Brake Line
This is similar to Step 2, except you are removing a rubber brake line from one of the front wheels.
Step 5 – Installing the New Front Rubber Brake Line
Install the new stainless steel rubber brake line on the caliper by using new crush washers on the brake lines. The line should be placed just like the original brake line was. The clip should be replaced and bolted with 10mm wrench at 11 ft-lb torque. Check to see whether the brake fluid needs to be replaced.
Step 6 – Final Checks
Once you have installed all of the new stainless steel brake lines, you will need to get rid of any air that is in the system by bleeding the brakes. Get a helper to check for any leaks.
If everything is installed properly, replace the wheels and remove the car jack stands before going for a slow test drive to make sure that you can stop.
