Brake hose Passat 3B6 rear and front

Brake hoses are always to be replaced in a set. The service life of these components is limited, so over time their performance characteristics deteriorate, and efficiency of transmitting the braking force reduces. Even if only one hose is damaged, the service life of the remaining hoses is most likely to have been expired.

To detach rusty fasteners of the hose to the caliper on the VW PASSAT Variant (3B6) vehicle, treat the joints with a special agent like WD-40. An attempt to unscrew a bolt by applying excessive force is fraught with expensive replacement of the caliper.

All work is to be performed in rubber gloves to protect your skin from aggressive liquids.

When the hose is disconnected, its tube should be immediately stopped with a plug made of materials at hand, to avoid leakage of brake fluid.

During replacement of brake hoses on the VW PASSAT Variant (3B6) vehicle, it is very important to ensure that the brake fluid is not spilled on the car body. Its components have a destructive effect on the paintwork, plastic and rubber parts of the vehicle.

Before installing new hoses, it is important to clean dirt from the threaded connections. However, no grease or sealant should be applied to their surface.

During the work, make sure that the hose is not twisted, otherwise operability of the brake system will be disrupted.

Check tightness of the brake system of the VW PASSAT Variant (3B6) vehicle by inspecting tubes, hoses, calipers and brake cylinders for absence of leaking.

Top up the brake fluid in the tank to the maximum level, as during hose replacement, small amount will leak out anyway.

Bleed the brake system of the VW PASSAT Variant (3B6) vehicle. For this purpose, you will need a transparent hose and a container half filled with brake fluid. One end of the hose is to be connected to the bleeder valve; the second end should be dropped into the container with the braking fluid. Then ask an assistant to press the brake pedal 3-5 times, and then hold it pressed for a few seconds. Next, loosen the bleeder valve to release air from the system, and when fluid without air bubbles begins to flow from the hose, tighten the valve. Repeat the procedure several times for each mechanism, starting with the rear wheel furthest from the master brake cylinder, and ending with the front wheel closest to it. When doing the work, make sure that the brake fluid level in the tank is always above the "minimum" mark.
