    Tech A says that when the brake pedal is depressed, a push rod creates the hydraulic pressure in the disc brake system. Tech B says that when the brake pedal is depressed, a push rod transfers the force through a brake booster to a hydraulic master cylinder. Who is correct? 
    • A. 

      Tech A

    • B. 

      Tech B

    • C. 

      Both Techs A and B

    • D. 

      Neither Tech A nor B

  • 4. 
    Tech A says that fixed calipers are rigidly bolted in place and cannot move or slide. Tech B says that the sliding or floating caliper has brake pads located on each side of the rotor, but all the pistons are on only one side, usually the inside of the rotor. Who is correct?
    • A. 

      Tech A

    • B. 

      Tech B

    • C. 

      Both Techs A and B

    • D. 

      Neither Tech A nor B

  • 5. 
    Tech A says that in disc brake calipers, the piston is sealed by a stationary round section sealing ring, also called a round cut O-ring. Tech B says that in disc brake calipers, the piston is sealed by a stationary square section sealing ring, also called a square cut O-ring. Who is correct?
    • A. 

      Tech A

  • 6. 
    Tech A says that manufacturers have dealt with caliper brake piston corrosion by making pistons out of a phenolic resin. Tech B says that even though the phenolic pistons themselves do not corrode, the cast-iron bore of the caliper does corrode and rust and can therefore cause a phenolic piston to seize in the bore. Who is correct?
