discuss the difference between a dual split and a diagonal split master cylinder.

Answers

Answer:

The difference between the dual split Master cylinder and diagonal split Master cylinder is dual split it makes power brakes less prone to failure while diagonal split is when the left rear and right front brakes are on one hydraulic line while the right front and left rear brakes are on another.

The distinction between a diagonal split and a dual split master cylinder Power brakes are less likely to fail when the master cylinder is dual split, while diagonal splitting occurs when the left rear and right front brakes are connected to one hydraulic line while the right front and left rear brakes are connected to another.

What is meant by master cylinder?

The hydraulic pump in a car's braking system, which includes a cylinder and one or more pistons and pushes hydraulic fluid under pressure to the brakes at each wheel, is activated by pressing the brake pedal.

In order to convert the pressure on the brake pedal to hydraulic pressure, the master cylinder, also known as the master brake cylinder, feeds brake fluid into the brake circuit and regulates this in accordance with the mechanical force.
