Some manufacturers include it in their maintenance schedules and others don't. Mercedes-Benz, for example, says brake fluid should be flushed and replaced with new fluid every two years or 20,000 miles. Volkswagen says that a brake fluid flush should be done on most of its models every two years regardless of mileage.
Also to know is, how do you work out brake efficiency?
Calculate the vehicle's weight. The weight of the vehicle can be found in the vehicle's manual. Divide the vehicle's weight by the total brake effort, and then multiply the number by 100 to get the brake efficiency percentage.
What is the braking ratio?
Braking ratio, usually expressed as a percentage, is the force pressing the brake shoes against the wheels compared to the weight of the car. For easy comparison, braking ratio normally is stated at 50 PSI brake cyl. pressure".
What is the braking system in a car?
A drum brake is a vehicle brake in which the friction is caused by a set of brake shoes that press against the inner surface of a rotating drum. A brake disc (or rotor in U.S. English), usually made of cast iron or ceramic, is connected to the wheel or the axle.
