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?

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

Technician A says that all slides and caliper bushings should be lubricated for proper operation. Technician B says that lubricant should not be used on disc brake parts because it can trap and hold dirt. Which technician is correct?

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.
