VW MKIV Jetta Golf GTI Brake Fluid Flush DIY

Quick and to the point, the reason to change your brake fluid is to save your ass! Brake fluid is a hydroscopic which means it attracts water, big deal right? Wrong, through the brake lines and through your resevoir brake fluid attracts water, water has a really low boiling point, the more water in your lines the lower your boiling point. So you smash the brake pedal to stop you from slaming into the car ahead of you but your brakes barely keep you from hitting him. Your pedal feel may be very "mushy" as some may say. Your pads and rotors are fine so what's the deal. When you slammed your brakes their is a good chance your brake fluid boiled, in turn becoming a gas. Which we all know you can compress gas a lot! So your pedal sinks to the floor. Of course that is worst case scenerio but that is the situation that we are trying to avoid by changing our fluid. Another reason is with our expensive ABS ESP etc. etc. we want to prolong their life as long as we possibly can, new brake fluid will keep corrosion to an absolute minimum.

Bentley Recommends changing your fluid every two years regardless of mileage. Which is a pretty safe bet, however those of us that drive our
asses off may want a bit more insurance, my recommendation is every 30,000 miles or 1 1/2 years. Whichever comes first. Mainly for the fact that in 2 years the fluid has already taken on too much water and is already doing too much damage.
Tools Required: Jack Jackstands, 11mm open ended wrench(9mm wrench for 6spd slave cylinder bleed) Motive power bleeder or equivalent, catch bottles or tubing to collect old fluid, turkey baster to remove old fluid from resevior.

Start with the simple part:
1.Begin loosening up your lugs on your wheels.
2.Jack up your vehicle and support it with jackstands.
3. Remove your wheels. This will let you have plenty of room to work and the front calipers it is nearly impossible to bleed without removing the wheels.
4.Due to variances in 1.8t, tdi, 2.0l, VR6, 3.2l. Remove whatever you need to to have good access to the front of the the brake fluid resevoir.
5. Now remove the yellow fluid level sensor from the brake fluid resevoir.
6. Next take out the plastic screen insert inside the resvoir with a flat head screwdriver as picture.
