Brake drums use ________ for the friction surface area.

Technician A says that hard spots in a brake drum should be removed using a carbide-tip machining tool. Technician B says that the drum should be replaced if hard spots are discovered. Which technician is correct?

The major reason for brake pedal pulsation during braking is due to ________.

After machining a rotor, what should be done?

Typical maximum rotor thickness variation (parallelism)specifications is ________.

Typical maximum rotor runout specifications are ________.

Rotor finish is measured in ________.

The lower the Ra of a rotor, the ________ the surface.

The brake lathe arbor should be checked using a ________.

A disc brake rotor is being machined. Technician A says that a feed rate of 0.0008 inch per revolution and 150 RPM is where the rotor should be set for a final cut. Technician B says that the rotor should be given a non-directional surface finish using 150 grit sandpaper. Which technician is correct?

Technician A says that brake drums on the same axle should be close to the same inside diameter for best brake balance. Technician B says that a brake drum may be cracked if it rings like a bell when tapped with a light steel hammer. Which technician is correct?

A hubless brake drum cannot be machined because it cannot be held in a lathe.

The major reason for brake pedal pulsation during braking is due to excessive rotor thickness variation.

Two technicians are discussing hard spots in brake drums. Technician A says the drum should be replaced. Technician B says the hard spots are caused by using riveted rather than bonded brake shoes. Which technician is correct?

Hard spots in a brake drum are caused by________.

Two technicians are discussing the machining of brake drums. Technician A says that most brake drums cannot be machined more than 0.060 in. oversize. Technician B says that brake drums on a common axle should be machined to within 0.010 in. of each other. Which technician is correct?

Two technicians are discussing disc brake rotorservice. Technician A says that the inner races (bearing cups) should be removed from the rotor before it is mounted on the lathe. Technician B says that a non-directional finish on the rotor surfaces can be obtained by using sandpaper. Which technician is correct?

Technician A says heat checking can be caused by numerous panic stops in rapid succession. Technician B says it can be caused by heavy braking. Which technician is correct?

Which is NOT a type of brake drum construction?

Which one is not a form of drum distortion?

Most manufacturers specify that the friction surfaces of a rotor must be parallel to within ________.

The chamfer on the inside edge of a brake drum usually indicates ________.

Technician A says anti-vibration devices only need to be used when resurfacing drums. Technician B says hubless brake rotors require special adapters when mounted on a bench lathe for resurfacing. Which technician is correct?

Technician A says there are no brake lathes that can machine rotors on the vehicle. Technician B says drums must be removed from the vehicle to be machined. Which technician is correct?
