Running gearGeneral notes
| The brake fluid is hygroscopic, that is, it has a tendency to absorb humidity and water from the air. |
|
|
|
| The boiling point decreases as the water content increases, which means a considerable rise in brake fluid temperature can lead to formation of vapour bubbles and brake failure. |
| The colour of the brake fluid becomes darker over the course of time. At the same time, a dark-coloured liquid must not mean that the quality is bad. The change in colour is due to chemical reactions and may happen after a short time (weeks), especially in the case of vehicles with ABS. |
WARNING | The rubber parts of the braking system (sleeves, seals) are not compatible with mineral oil, petrol or cleaning products. |
|
| Contact between such substances and a seal or sleeve, including in small quantities, will cause modifications to these parts and could negatively affect brake operation. The consequences of a contaminated brake system may only become apparent after some months, however this could imply considerable costs, above all for vehicles with ABS/ESP. |

| B = Brake hose - swollen due to contact with mineral oil |
| Summary of the above mentioned points: |
| Ensure that the brake fluid containers are always completely sealed. This is the only way to ensure that oil, dirt, cleaning products and humidity do not enter. |
| Store the brake fluid containers separately from oil containers (including hydraulic oils) and cleaning products, in order to avoid any possible mixing or filling error. |
