Flushing a brake system is one of the repairs a car owner can perform themselves.

Pay attention to enable safety

It does not always require the services of a professional mechanic to complete car repairs, and among these projects that can be accomplished by a car owner is the ability to flush a brake system. Over time, the brake fluid in a car can become ineffective due to the extreme heat and moisture that it is exposed to and a brake system flush them becomes necessary to replace the old brake fluid with new. No tremendous mechanical skills are needed to flush a brake system, just the ability to locate the brake fluid reservoir and the brake calipers, wheel cylinders and brake system bleeder screws. It should be noted to use caution when handling brake fluid because it is extremely corrosive, and can damage car parts and paint when spilled.

The first step to flush a brake system is to put the car in park with the parking brake on and the ignition turned off. Lift the car hood and locate the brake fluid reservoir, which is usually found at the rear of the engine near the car windshield. Remove the cap or caps from the brake fluid reservoir and using an ordinary turkey baster remove as much brake fluid from the reservoir as is possible. After consulting your car's owner manual, refill the reservoir with the proper type of brake fluid and replace the caps on the reservoir.

To complete the next step in flushing a brake system you will need two people - one to sit inside of the car and the other outside of the vehicle. The individual inside of the car depresses the brake pedal to the floor, while the person outside of the car loosens the bleeder screws on either the wheel cylinders or the brake calipers depending upon the model of the vehicle. While the brake pedal is still depressed the person outside of the car then tightens each bleeder screw, and then the person inside of the car slowly allows the brake pedal to rise to it's normal position. These actions may need to be repeated several times until the brake system master cylinder is full of new brake fluid.

If performed properly the brake pedal should feel firm and responsive - if not, chances are more flushing is needed until the brake pedal feels right. When satisfied with your repair take the vehicle for a very short drive on a level surface to check for stopping power before venturing out into normal traffic conditions.
