Replacement of brake lines and hoses (VW Beetle)

Reinforced hoses are used to connect the moving parts of the brake system, and steel pipelines are used to connect the fixed parts.

The pipeline connections are made in the form of conical couplings. The ends of the pipelines have a conical mating surface with threaded holes in the brake cylinders or in the distribution elements made with a conical base. A union nut is installed in front of the cone on the pipeline, which, after tightening, presses the conical surface of the pipeline connection to the conical base of the hole and thereby ensures a reliable sealing of the connection.

Replacement of pipelines

Brake system lines should be checked every 7,500 km.

First of all, it is necessary to monitor the appearance of traces of rust and mechanical damage, as well as dents from stone impacts.

Caution! Damaged brake lines must be replaced promptly, as they can burst during sudden braking.

Remove the brake line (when installing a new pipeline, lay it in place of the old one).

When connecting the pipeline, lubricate the conical mating surface with a few drops of brake fluid and tighten the union nuts to a torque of 15-20 Nm (1.5-2.0 kgf/cm).

Bleed the brake system (see section below "Bleeding the brake system").

Replacing hoses

Remove the wheel.

Loosen the nut and remove the hose bracket.

Disconnect the brake hose from the wheel brake cylinder.

Install the new brake hose without twisting (tightening torque 15-20 Nm(1.5-2.0 kgf/cm)).



After installing the hose, check with the wheel unloaded (lift the car), does the hose follow the movement of the wheel without friction against surrounding parts?.

Caution! Do not allow oil or gasoline to come into contact with brake hoses, and do not coat them with varnish or underbody preservative.
