Brake fluid should be checked routinely to ensure both its level and condition. If the reservoir is low, add brake fluid to fill up the system. Use the same type of brake fluid you used before but don't use old fluid. Open up a new container even if that means you will be throwing most of it away. Brake fluid is hygroscopic, which means it absorbs water, and old brake fluid will have degraded.
Note the color of the fluid in the reservoir. It should be clear. If it is cloudy, then it has absorbed moisture and may be dirty. In that case you must flush the braking system?-a procedure that replaces the brake fluid. If you have ABS brakes, then there are many delicate VW parts involved and this is probably an operation you will need a qualified mechanic for.
Know Your Brakes
As you drive your car you will get a feel for how your brakes work. When you drive someone else's car one of the first things you probably notice is that their brakes are different. They may require more pressure or less and it often takes a bit of driving before you are comfortable with them.
The first person who can diagnose brake problems is you, not your mechanic. You know how the brakes feel. If they suddenly start to feel different, that's a sign that something is wrong. Inspect your brakes or take the car to a mechanic immediately. These are not VW parts you want to ignore.
Listen To Your Car
Contrary to popular belief, squealing does not necessarily mean you have a problem with your brakes. In could be that the brake pads are dirty or perhaps a stone is caught between the pad and the rotor. The next time you wash your car, spray a little water on the brake pads. This will wash off the dirt and the squealing will probably go away. Be cautious though. Squealing can also be a sign of seriously worn brake pads or harmful vibrations so it's a good idea to take a look at your braking system. If you're not skilled enough, have your technician take a look right away.
A pulsing noise on the other hand is often a sign of trouble. Instead of a long squeal you will get a rhythmic noise and sometimes you can feel a pulsing through the brake pedal. This can mean a warped rotor and that means it's time to contact a VW parts specialist. A pulsing can also indicate pad transfer which is easier to remedy.
In the same vein a harsh grinding sound or a squeaking sound that is constant rather than just as you stop can both be indicators of more serious brake problems. Don't delay. If you suspect brake problems, get the car inspected right away.
