Wires stretch and sag. Hydraulic fluids transfer force with far smaller losses.

What are the uses for a hydraulic pump?

Hydraulic drive systems like gear pumps, rotary vane pumps, screw pumps, bent axis pumps etc. One real life example of hydraulic pumps is the brake master cylinder in a car. You also see hydraulic pumps in excavators.


What is the fluid used in Hydraulic brake?

Because oils damage rubber seals and hoses in the braking system, brake fluids are not petroleum-based. Most brake fluids used today are glycol-ether based, but mineral oil (Citroën liquide hydraulique minéral (LHM) and silicone (DOT 5) based fluids are also available.


Why aren't hydraulic brakes used for rear wheels when the same is used for the front wheels?

All modern mass-produced cars and light trucks DO have hydraulic brakes on the front and the rear wheels. Heavy trucks generally have air brakes on all the wheels. Maybe you are thinking of cars that have disk brakes on the front and drum brakes on the rear? On cars, these are both hydraulically operated using the same hydraulic (brake) fluid. In normal stopping situations, the front brakes do more work than the rear brakes. Maybe 70 or 80% of the braking is done by the front wheels (it depends on where the weight is in the car and how fast you stop). Disk brakes are a somewhat better brake for a car, but drum brakes are a little cheaper to manufacture. So, disk brakes are almost always used on the front wheels where the braking is more important. Drum brakes are used on the back of some cars to save money. Note that performance cars (sports cars) almost always have disk brakes on all of the wheels.


Why is it called brake horsepower?

Brake horse power is the amount of engine power which makes it to the wheels. This is different from the actual output at the engine.

What are the main differences between a mechanical brake and a hydraulic brake system?

The main difference between a mechanical brake system and a hydraulic brake system is the way they transmit force to stop a vehicle. In a mechanical brake system, force is applied to the brakes through a cable or linkage, while in a hydraulic brake system, force is transmitted through a fluid-filled system using hydraulic pressure. Hydraulic brakes are generally more efficient and provide better braking performance compared to mechanical brakes.

How can I convert a mechanical brake system to a hydraulic brake system?

Converting a mechanical brake system to a hydraulic brake system involves replacing the mechanical components with hydraulic ones. This includes installing a master cylinder, brake lines, calipers, and possibly a new brake pedal. The hydraulic system uses fluid pressure to apply the brakes, providing smoother and more efficient braking compared to mechanical systems. It is important to ensure that all components are compatible and properly installed for safe and effective braking performance.
