Brake Caliper Ch 105

What part causes the disc brake caliper piston to retract when the brakes are released?

• The square cut O-ring

• The rotating rotor (disc) that pushes the piston back

• Return (retracting) spring

• The caliper bushings

Slots are often used in brake pads because they _______.

• improve braking performance

• increase brake life

• reduce brake noise

• reduce brake fade

Which of the following is NOT a component of a disc brake system?

• Splash shield

• Caliper

• Brake pads

• Backing plate

Technician A says that riveted disc brake pads are often quieter than 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

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 is correct?

• Technician A only

• Technician B only

• Both technicians

• Neither technician

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

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 is correct?

• Technician A only

• Technician B only

• Both technicians

• Neither technician

Which type of disc brake caliper may leak fluid more often?

• Fixed

• Single piston

• Floating

• Sliding

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

A four piston caliper is used in what type of caliper design?

• Sliding

• Floating

• Either fixed or floating

• Fixed
