Tip & How-To about 2006 Audi A8
We, as do all experts, recommend flushing your Audi & BMW brake fluid annually. This is an important maintenance service do to the fact brake fluid is hygroscopic which means your brake fluid absorbs water ( moisture ) from the air. Yes, your reservoir is tightly capped but the laws of physics require it be vented to atmosphere. There in lies the problem. This moisture not only lowers the fluids boiling point, leading to a spongy brake pedal on frequent or long hard stops, but if unchecked will lead to expensive corrosion damage to all the systems metal parts! Note!! We DO NOT recommend replacement with silicone based brake fluid! Unless you are driving your car extensively at the track and have completely disassembled the system and purged all lines, valves and ABS hydraulic unit, some mineral fluid will remain in pockets. The two fluids do not mix! Besides the corrosion problem, these pockets have a much lower boiling point, usually in the calipers where heat is most concentrated ! i.e., unexpected lose in brake pedal feel and dangerous increase in stopping distance!
