30s - Q2
Slots are often used in brake pads because they ________.
improve braking performance
reduce brake fade
reduce brake fade
increase brake life
30s - Q3
Which of the following is NOT a component of a disc brake system?
Caliper
Backing plate
Brake pads
Splash shield
30s - Q4
Technician A says that riveted disc brake pads are often quieter that bonded disc brake pads. Technician B says that integrally molded disc brake pads are molded into holes in the steel backing of the pads. Which technician is correct?
Technician A only
Technician B only
Both technicians
Neither technician
30s - Q5
Two technicians are discussing the reason that the brake fluid level in the master cylinder drops. Technician A says that it may be normal due to the wear of the disc brake pads. Technician B says that this is part of the wear compensation feature of disc brakes. Which technician iscorrect?
Technician A only
Technician B only
Both technicians
Neither technician
30s - Q6
Two technicians are discussing a floating-type disc brake caliper. Technician A says that if the caliper slides are corroded, one pad may wear more than the other pad on the same wheel brake. Technician B says that if a caliper slide is corroded, reduced braking may occur. Which technician is correct?
Technician A only
Technician B only
Both technicians
Neither technician
30s - Q7
Technician A says that disc brakes are self adjusting and the brake pedal height should not become lower as the disc brake pads wear. Technician B says that as the disc brake pads wear, the level of brake fluid in the master cylinder reservoir drops. Which technician iscorrect?
Technician A only
Technician B only
Both technicians
Neither technician
30s - Q8
Which type of disc brake caliper may leak fluid more often?
Fixed
Floating
Single piston
Sliding
30s - Q9
Technician A says that all vehicles equipped with rear disc brakes use a parking brake that is integrated in the caliper. Technician B says that all vehicles equipped with rear disc brakes use a small drum brake inside the rear rotor for a parking brake. Which technician is correct?
Technician A only
Technician B only
Both technicians
Neither technician
30s - Q10
A four piston caliper is used in what type of caliper design?
Floating
Fixed
Either fixed or floating
Sliding
30s - Q11
A quick take-up master cylinder is required when what type of caliper design is used on a vehicle?
Sliding
Low-drag
Two-piston
Fixed
30s - Q12
Technician A says that brake fade due to lining or water is not possible on disc brakes. Technician B says that lining and water fade can occur on disc brakes, but is not as likely compared to drum brakes.Which technician is correct?
Technician A only
Technician B only
Both technicians
Neither technician
30s - Q13
Technician A says that one disadvantage of disc brakes is noise. Technician B says that disc brakes have more holding power as a parking brake compared to drum brakes. Which technician is correct?
Technician A only
Technician B only
Both technicians
Neither technician
30s - Q14
When the pressure in a caliper is released, the piston is moved back in the cylinder by ________.
the leverage of the caliper arms
the opening of the vent port
spring pressure
the action of the piston seal
