Installing rear brakes / Determine cable diameter / Metric bolts

Mounting the rear brake parts runs quite similarly to this one for the front brakes. We discussed the front brakes in edition 22. We'll start by assembling the wheel brake cylinder. In edition 22 we showed how to prepare a wheel brake cylinder for the front brakes for assembly. It is no different with the rear brakes. The wheel brake cylinders must be treated against corrosion. Read edition 22 starting on page 39 to learn how to prepare the brake cylinders for installation.

Voltage losses will occur when, for example, the contacts of a switch are corroded or when the spring tension of a switch or fuse holder is no longer as it was when it came from the factory. The smaller the electrical resistance of the consumer, the more it will consume but the more it will depend on voltage losses across the cables. As most of us have already experienced, the starter motor, wiper motor and headlights are the first victims of an electrical circuit that has voltage drops.

While working on old Volkswagens, it is common to encounter bolts that do not belong to that application for which they are used. Too soon inexperienced enthusiasts will replace a bolt with another bolt they have available. The result can be that the thread in for example the body, chassis or rotule is damaged, you will notice that immediately. Worse is when a bolt breaks after some time due to overloading, you do not want to experience that when it comes to brakes or suspension. Thread, tensile strength, cylindrical or conical, are just some of the important properties of bolts.
