tech a says that disc brake pads require much higher application pressure to operate than drum brake shoes because they are not self - energized. tech b says that disc brake pedal travel is lengthened to move the additional fluid being displaced by the larger caliper pistons. who is correct? select one: a. tech a b. tech b c. both techs a and b d. neither tech a nor b

tech a says that disc brake pads require much higher application pressure to operate than drum brake shoes because they are not self - energized. tech b says that disc brake pedal travel is lengthened to move the additional fluid being displaced by the larger caliper pistons. who is correct? select one: a. tech a b. tech b c. both techs a and b d. neither tech a nor b

Answer

Brief Explanations:

Disc - brake pads are not self - energized like some drum - brake shoes, so they need higher application pressure, which makes Tech A correct. Also, larger caliper pistons in disc brakes displace more fluid, leading to increased pedal travel, so Tech B is correct too.

Answer:

C. Both Techs A and B
