In this video I’m showing you how I to do a complete service on Alexa, our 2009 Opel Astra hatchback: oil & oil filter, sparkplugs, air filter, air cabin filter, brake fluid flush and wipers.
Brake fluid 101
What makes good brakes? Sure, you have all the mechanical components like the master cylinder, the brake rotor, caliper, pads and so one. However, none of that would ever really run properly if it wasn’t for the brake fluid. The brake fluid is used to transfer the brake force you apply on the pedal into pressure on the brake pads that eventually push against the rotor and through friction slow the wheel down.
Even though the brake fluid circuit is closed, there are several occasions which require it to be changed or at least topped up. For example, when installing new brake pads or a complete new set of brakes or simply when the fluid has gone past its expiration date. As a matter of fact, brake fluids are hygroscopic (water absorbing), which means they absorb moisture from the atmosphere under normal humidity levels. The RCZ such as many other passenger cars uses DOT 4 brake fluid, which is supposed to be changed every two years.
