Vehicle Hydraulic System service is relatively uncomplicated, but it is vital to the vehicle's safe operation.
Brake Fluid Inspection
The master cylinder is usually located under the hood and near the fire wall on the driver's side. Remove the cover and check the gasket, or diaphragm. Inspect the cover for damage or plugged vent holes. Clean the vent holes, if necessary.
Check the brake fluid level in the master cylinder. A cast-iron reservoir is usually filled to within 1/4 inch of the top. A plastic reservoir may have fluid level mars. Do not overfill a reservoir. If fluid must be added, a leak probably has developed or the shoes and/or pads are worn. Check the system carefully to locate the leak.
To check for contaminated fluid, place a small amount of brake fluid in a clear glass jar. If the fluid is dirty or separates into layers, it is contaminated. Contaminated fluid must be replaced.
Contaminated brake fluid can damage rubber parts and cause leaks. When replacing contaminated brake fluid, it is necessary to flush and refill the brake system with new fluid. Always use fluid with a DOT rating of 3 or higher. Follow manufacturer's recommendations.
Check the master cylinder for dampness and leaks around the body fittings, especially at the rear. A leak where it is mounted to the fire wall or power brake unit indicate a defective rear piston seal. The master cylinder must be rebuilt or replaced.
Brake Line Inspection Check all tubing, hoses, and connections from under the hood to the wheels for leaks and damage. Wheels and tires should also be inspected for signs of brake fluid leaks. Check all hoses for flexibility, bulges, and cracks. Check parking brake linkage, cable and connections for damage and wear. Replace parts where necessary.
Brake Pedal Inspection Depress and release the brake pedal several times (engine running for power brakes). Check for friction and noise. Pedal movement should be smooth, with no squeaks from the pedal or brakes. The pedal should return quickly when it is released.
When operating the engine, be sure the transmission lever is in neutral or park. Be sure the area is properly ventilated for the exhaust to escape.
Apply heavy foot pressure to the brake pedal (engine running for power brakes). Check for a spongy pedal and pedal reserve. Spongy pedal action is springy. Pedal action should feel trim. Pedal reserve is the distance between the brake pedal and the floor after the pedal has been depressed fully. The pedal should not go lower than 1 or 2 inches above the floor.
With the engine off, hold light foot pressure on the pedal for about 15 seconds. There should be no pedal movement during this time. Pedal movement indicated a leak. Repeat the procedure using heavy pedal pressure (engine running for power brakes).
If there is pedal movement, but the fluid level is not low, the master cylinder has internal leakage. It must be rebuilt or replaced. If the fluid level is low, there is an external leak somewhere in the brake system. The leak must be repaired.
Depress the pedal and check for proper stop light operation.
To check power brake operation, depress and release the pedal several times while the engine is stopped. This eliminates vacuum from the system. Hold the brake down with moderate foot pressure and start the engine. IF the power unit is operating properly, the brake pedal moves downward when the engine is started.

Braking: a Way of Life
A long time ago, automobiles were in their infancy and there was no way to stop a moving automobile. Then brakes came along. Brakes were devices that slowed or stopped a moving vehicle and prevented it from moving again.
Early braking devices consisted of curved wooden blocks designed to bear against the steel tires. This was manipulated using a single leverage system from the driver's seat. This “brake shoe” was the normal way of braking, either a horse-drawn vehicle or even a steam locomotive. Different designs, using levers, rods and pivots, were used to operate them.
By the end of the 20th century, the Michelin brothers began the movement, shifting away from the old way of braking. As automobiles shifted to pneumatic rubber wheels, new ideas of braking were needed, as “brake shoes” were no longer apt for the situation.
A new method (which has two kinds), in which attempted to apply the force of friction to the axle or to a drum on the axle or even to the transmission shaft, was used. This braking system was activated when the driver pushed a pedal down or operated a lever. Continuously applying pressure until it was heavy enough caused the bands to contract more slightly around the drum, giving it more greater retardation.
One instrument used a wooden block inside a flexible contracting metal band, which, when pressed together, would tighten around the drum. This causes friction between the drum, which is then connected to the wheel, then to the wooden blocks on one end, and eventually slowed down the vehicles' forward progress.
The other used an inner wheel or brake drum which had an added external contracting meant to wrap around the drum, slowing down or preventing the vehicle from moving forward. But this meant that the drum had to be constantly replaced, leading to poor friction quality.
Past forward to the 21st century. Newer braking systems, which used hydraulic fluids and the like to stop a vehicle became in vogue. One such system used a vacuum. The vacuum became a tool, in which it operated a brake booster. Modern cars, such as your Volkswagen, uses this method in its VW brake parts.
Another method to stop moving vehicles meant using disc brakes. Friction is applied on the discs, courtesy of brake pads mounted on brake calipers. Your VW brake parts are equipped with brake calipers that would apply the necessary amount of friction on the discs to slow or stop the car.
So start giving attention to the way your car behaves, especially when you step on the brakes. Any squealing noise, leaking or pulling coming from your VW brake parts can be a potential disaster waiting to happen. If these happen, take your Volkswagen to the nearest dealership and have the brakes inspected and even replaced. Your life and your loved ones depend on that little piece of machinery.

changing over bike brake levers?
i have just bought a hardtail mountain bike and want to change the size of the brake leavers from regular size to small. im just wondering if it is possible to just buy and size brake lever and just change over or do i have to buy a specific lever, the brake levers at the moment are Tektro Auriga Comp Hydraulic Disc. thanks
This is a Hayes brake lever and system and unfortunately I do not think they make just an aftermarket lever for this one. You will have to buy an entire brake system to get what you want.
A Final Gulp or Two as the Party Winds Down
For today’s speed eaters, the E63 AMG feels like a two-ton burrito in habanero sauce: driving it is akin to the last gas-spewing binge before the diet begins.
