Volkswagen Golf Service & Repair Manual: Instructions for checking
| The following instructions are intended to help you find the
causes of problems effectively and objectively in the event of
complaints about the brake servo or in the event of a so-called
»hard brake pedal«. |
| This check relates to the following components: |
| Oil seal between brake master cylinder and brake servo. |
| Vacuum hoses with connectors |
| When evaluating the measuring results, bear in mind that
they will be influenced by the geographical location. The higher
your location is above sea level, the lower the air pressure
will be. |

following prerequisites for checking: |
| Visual inspection of all vacuum hoses for damage (e.g.
cracks or marten bite) and to check that they are correctly and
firmly attached |
