This could be a result of a. failure to install the dampening belt b. cutting too slowly c. dull cutting blades d. cutting speed too fast -- A : failure to install the dampening belt why : a missing dampening belt could cause the drum to vibrate while on the lathe. this vibration can cause the drum to bounce on the cutting tip and make a chattering noise A vehicle equipped with a hydro-boost brake system has a hard pedal with little braking action. Which of the following could be the cause? a. low brake fluid b. air in the brake fluid c. low power steering fluid d. an overtightened power steering belt -- C : low power steering fluid why : low power steering fluid can cause the booster to provide very little if any boost Which of the following could cause excessive noise braking? a. worn wheel cylinders b. worn caliper pistons c. seized caliper slides d. missing clips -- D : missing clips why : missing anti-rattle clips could cause excessive noise while braking A vehicle equipped with a "hill holding" option has an ABS code. Which tool would most likely be used to check the wheel speed sensor? a. AC volt meter b. Ohm meter c. Scan tool d.

A & B d. neither A OR B -- D : neither A OR B why : neither technician is correct. this style of pin should be installed with a torx or hex head socket Technician A says a hydro-boost system can use the power steering pump to operate the booster. Technician B says a hydro-boost system can use engine vacuum to operate the booster. Who is correct? ( pg. 47 ) a. A b. B c. A & B d. neither A & B -- A : only A why : only tech A is correct. a hydro-boost system uses hydraulic pressure to create boost A disc brake caliper is dragging. All of the following could be the cause EXCEPT a. binding pins b. sticking piston c. binding caliper d. worn brake pads -- D : worn brake pads why : worn brake pads will not cause the brakes to drag Which operation is being performed in the illustration?
