How to Repair My 1999 Toyota Corolla's Leaking Brake Line

Inspecting the brake lines and hoses on the Toyota Corolla should be part of your regular maintenance routine. Leaking lines and hoses will result in loss of brake fluid and the brakes will not work properly. You need to check that the fittings are tight periodically, that that there are no holes or kinks in the hoses and lines that will restrict the flow of brake fluid to the wheel cylinders. If you find any damage at all, you need to replace the line right away.

Instructions

1

Place a set of wheel chocks behind the rear wheels if the leak is in the front or in front of the front wheels if the leak is in the rear. Lift the Corolla on the side that you need to work with using the automobile jack. Place a jack stand under the vehicle and raise it to the frame. Loosen the lug nuts using the lug wrench and take the wheel from the Corolla.

2

Check the brake line in question. If it is leaking around the fitting, try tightening the fitting with a wrench. If it is leaking in the line itself, you need to replace it. Place the drain pan under the brake line and loosen the fitting with the wrench. Allow the fluid to drain. When it is done, move the drain pan to the other end of the line and loosen the fitting with the wrench.

3

Pull the brake line from the mounting clips and remove it from under the Corolla. Put the new brake line into the mounting clips and then tighten both fittings using the wrench. Add fresh brake fluid to the master cylinder. Install the wheel on the Corolla and tighten the lug nuts with the lug wrench. Remove the jack stand from under the Toyota.

4

Lower the Corolla to the ground. Bleed the brakes by having a helper to pump and hold the brakes while you open the bleeder valve with a wrench to expel the air from the lines. Continue this process until all of the air is gone from the brake lines. Add more brake fluid to the master cylinder if necessary.
