Understanding Automotive Disc Brake Systems

What is the primary function of the master cylinder in a disc brake system?

• To store brake fluid

• To transfer pedal force to the calipers

• To cool down the brake system

• To increase the brake fluid pressure

Which component is directly pushed by the brake pedal?

• Secondary piston

• Primary piston

• Push rod

• Compensating port

What is the function of the compensating ports in the master cylinder?

• To allow brake fluid to flow back into the reservoir

• To increase pressure in the cylinder

• To connect the primary and secondary pistons

• To release excess brake fluid

What happens when the primary piston closes the first compensating port?

• Secondary piston is pushed

• Pressure in the cylinder decreases

• Brake pedal becomes easier to press

• Brake fluid returns to the reservoir

What is the consequence if the primary piston fails?

• The brake fluid leaks

• The secondary piston can still operate

• The brake system stops working

• The brake pedal becomes loose

How does the brake booster assist in braking?

• By storing extra brake fluid

• By reducing the effort needed to press the brake pedal

• By cooling the brake fluid

• By increasing the brake fluid volume

What role does the vacuum from the engine play in the braking system?

• It cools down the system

• It increases brake fluid pressure

• It assists the brake pedal via the brake booster

• It lubricates the master cylinder

What component is introduced to make applying brakes easier?

• Inlet port

• Fluid reservoir tank

• Brake booster

• Secondary piston

Which component ensures that the braking effort is minimized?

• Master cylinder

• Push rod

• Secondary piston

• Brake booster

What happens inside the servo when the brake pedal is pressed?

• Brake fluid is heated

• Air is filtered and assists in pushing the push rod

• Vacuum pressure decreases

• The diaphragm contracts
