Things You'll Need:
- Replacement brake lines
- Jack and jack stands
- Tire iron
- Line wrenches
- Vinyl tube
- DOT 4 brake fluid
-
Step 1
Lay out the entire replacement brake line kit made for your Passat. The best kits should come with six to eight lines made of stainless steel wrapped in PVC and a maximum of 20 inches long. Read all instructions that come with the kit.
-
Step 2
Support the car on jack stands and remove the first wheel. Trace the brake line from the hose to the last section connected by bolts.
-
Step 3
Study the existing section of brake line and bend the replacement line in the same way.
-
Step 4
Remove the brake line from the car by disconnecting the bolts with a line wrench. You'll need two line wrenches for the two bolts on each connector.
-
Step 5
Install the replacement line. Thread the bolts by hand, and then tighten with your line wrenches.
-
Step 6
Bleed the brake system to remove air from it. Open the bleeder valve on the caliper and connect it to a container of brake fluid with a vinyl tube. Have another person hold down on the pedal to purge the air.
-
Step 7
Replace the wheel and repeat the process for the other three sections. Refill the master cylinder reservoir with DOT 4 brake fluid and test the brakes after all lines are replaced.
