How to Replace a Brake Line in a Jeep Grand Cherokee

by Contributor

If you drive your Jeep Grand Cherokee through tough, off-road conditions, consider reinforcing parts like the brake lines. Changing the line sections directly connected to the brake hoses with stainless steel pipes increase their durability.


Step 1

Look under the hood and locate the Grand Cherokee's master cylinder reservoir on the driver's side. Top off the brake fluid and seal the cap tightly to reduce the amount of fluid lost during the replacement process.

Step 2

Lift the vehicle and support it on jack stands. Remove the wheel to reach the brake line and caliper.

Take a look at the existing brake line and bend the replacement line accordingly to reduce strain while driving.


Step 1

Remove the brake line at the brake hose first. Undo the two bolts on each connector using two line wrenches.

Step 2

Attach the new brake line, starting at the end farthest from the brake hose to avoid stretching the hose. Tighten the bolts with the wrenches after applying them by hand.

Step 3

Bleed the system of air. Open the caliper bleeder valve, attach a vinyl tube and place the end in a container with some brake fluid. Have an assistant press the brake pedal to remove the air.

Put the wheel back on and repeat the process on the next wheel. Test the brakes once you've replaced all four lines.


  • Review the condition of the brake hose and replace it as well if it shows signs of damage.
