As an independent Vw service garage with over 23 years of hands-on experience, we know what fails on Vws and why. We feel that changing your fluids is one of the most important preventive maintenance routines. Yet, for many Vw owners, this seems to be one of the most neglected areas of maintenance. Thoroughly flushing your fluids at the proper intervals can help your Vw reach 150,000 miles and beyond!
You should perform a Vw brake fluid flush every 30,000 miles or 3 years. It's important to use the right brake fluid. We recommend DOT 4 Vw brake fluid, which meets necessary fluid specifications. Changing Vw brake fluid is recommended and easiest when performing Vw brake rotor or pad service. Alternating between the 2 different colors makes it easy to know when you've completely flushed out the old Vw brake fluid.

We recommend flushing the brake fluid system about every 30,000 miles or 3 years. Changing Vw brake fluid is recommended and easiest when performing Vw brake rotor or pad service. Most Vw's came from the factory with a light amber colored brake fluid. If your original Vw brake fluid has turned a dark amber color it can be changed using the DOT 4 brake fluid above.
Note: If your Vw brake fluid was filled with a lower grade brake fluid, it needs to be changed sooner. This is because lower wet boiling point brake fluids accumulate more moisture (see the paragraph below for the dangers of moisture in the brake fluid).
The Vw brake fluid reservoir is vented and thus has entry points for dirt and moisture. Rubber brake hoses are permeable and over time allow moisture to get into the brake fluid. Vw brake fluid is like a sponge. Something as simple as moisture can be a real problem. Moisture in the Vw brake fluid changes its composition, leading to a lower boiling point for the fluid. This causes a vapor leak in the Vw brake system, resulting in brake fade. Contaminated brake fluid moving through the brake lines also leads to sediment building up in the brake caliper, affecting the cylinder bores. Some of this dirt and moisture laden fluid also travels to the ABS unit where it causes the solenoids inside to behave erratically. Just 2% moisture in Vw brake fluid is considered excessive. A 3% contamination level in DOT 4 brake fluid can lower the boiling point nearly 50%.
Note: We don't recommend silicone brake fluids (labeled DOT 5). It is true that the fluid itself is known for being immune to moisture, but rather than absorbing it, it enters the brake system and begins to collect in the Vw brake calipers. We feel DOT 5 silicone brake fluid can cause faster wear on the brake system seals. In our own repair service facility we've seen the best results from the above DOT 4 Vw brake fluid.
This is a basic overview of how we flush Vw brake fluid. It is not intended to replace the factory manual. Please refer to the factory manual for detailed instructions.
Changing Vw brake fluid is recommended and easiest when performing Vw brake rotor or pad service.
Refer to the factory manual for Vw brake fluid system instructions.
We recommend having an A.S.E. certified Vw mechanic change your Vw brake fluid.
Always wear gloves and wear safety goggles when handling Vw fluids.
Getting Vw brake fluid on your vehicles paint finish will damage it.
There are several different methods that are used to flush Vw brake fluid:
• Pressure bleeding
In our experience vacuum brake bleeders and inexpensive pressure bleeders don't work well because they cannot pull the Vw brake fluid through the ABS unit. You'll need an expensive commercial grade pressure bleeding unit to work effectively.
• Gravity bleeding
We use this method in our own repair shop. Gravity bleeding works very well using automotive lifts that suspend the car 6 ft in the air.
• Pedal bleeding
Occasionally the good old fashion pedal bleeding is employed. This method always works and isn't that hard to do.
