Tip & How-To about 2006 Audi A8

Flushing brake fluid

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!

What do I need to have done for the 60,000 miles maintainance?


The following items are recommended on your vehicle at 60k miles. Automotive Maintenance is very important to the longevity of your vehicle.

1. Change Engine Oil
2. Inspect Brakes
3. Replace Engine Air Filter
4. Replace Spark Plugs and Wires
5. Inspect tie rod ends and boot seals
6. Inspect and if necessary replace the PCV Valve
7. Adjust generator belt
8. Flush the Automatic Transmission Fluid and Filter

None of these services are ABSOLUTELY required, but are essential in keeping your car running to the best of it's ability.

A service garage stated that my 2006 Saturn Ion 2 with 39,0000 miles needs a brake system flush=$99.95 and a fuel induction service=$139.95. Is this normal maintenance service?


Although there are no set service intervals for brake fluid service, it should be done at regular intervals. Brake fluid is highly hygroscopic, meaning that it absorbs moisture very well, even from the air. The moisture absorbed will lower the boiling point of the brake fluid and can give you that spongy feel when you depress the pedal. So getting back to your question, if this is normal service? The best answer is that it could be. Of all of the fluids in a vehicle, brake fluid is the most neglected but one of the most important. I cannot tell you what service interval to use but set it mentally and keep to that interval. I personally use 3 years or 36000 miles.
As for fuel induction service, this is not normal service.

My car was driving fine. It's a 2006 BMW 750 Li. WE take very good care of it. BMW suggest flushing the brakes as part of maintenance and I did. Three weeks later after paying $1500.00 for flushing brakes and other maintenance. The car brakes down again. This verbage is directly from BMW ''car needs the brake booster, master cylinder and vacuum pump. The estimated total is $2869 for the repairs''. Come on, it's 2006, 75K hwy miles. Could all of this happen after the transmission failed on it 3 months ago and now this?


hi well no not really the transmission and the brakes have absolutely nothing in common. brake booster? ummm..dont think so, master cylinder is a good possibility 2 ways to find that out, check inside under dash where brake pedal is, if its damp there is a good chance its the master cylinder, if not, where the you put the brake fluid, check the under it see if its wet, see if the brake servo has fluid around it as well the other thing it could be is air i the brake line and that could mean something is letting in air the way to check this is, run motor, press brake semi hard, then without taking foot off brake pedal slightly raise your foot ( but keeping pedal down ) then do it again if it starts to "sink" this means there is air in the system hope i have understood your question...

want to do routine maintenance. is the filter


The filter is NOT in Hyundai's maintenance schedule (it's internal). However, if there's been a major malfunction of the transmission, the filter is replaced during overhaul.... It is not a routine maintenance requirement. However, the fluid is recommended to be replaced/flushed every 30,000 miles to assure warranty coverage. Contact your nearest Hyundai Service Center for more facts.
