ASE BRAKES A5 TEST (EXAM 1), ASE A5 BRAKES, ASE BRAKES A5 (EXAM 3), ASE BRAKES A5 TEST (EXAM 2) ALL IN ONE PERFECT STUDYPACK UPDATED 2023 WITH DETAILED RATIONALES A drum is chattering on the brake lathe. This could be a result of a. failure to install the dampening belt b. cutt ing 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 cali per 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 chec k the wheel speed sensor? a. AC volt meter b. Ohm meter c. Scan tool d. Ammeter C : scan tool why : a scan tool or oscilloscope can be used to test a signal from a digital when speed sensor The brake system has a soft, sinking pedal with the engine runni ng. The brake fluid level is at the correct height. Which of the following could be the cause? a. a restricted vacuum hose b. a leaking master cylinder c. a bypassing master cylinder d. a stuck open vacuum check valve C : a bypassing master cylinder why : a bypassing master cylinder would cause a low pedal and would not cause a loss of fluid Technician A says the pins should be driven in with a brass hammer. Technician B says the pins should be lubricated with brake fluid. Who is correct? ( pg. 47 ) a. A b. B c. 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 p erformed in the illustration? ( pg. 48 ) a. wheel cylinder bleeding b. brake caliper bleeding c. master cylinder bleeding d. master cylinder pressure test C : master cylinder bleeding why : the master cylinder is being bleed prior to installation The rea r wheels of a front wheel drive car lockup during heavy breaking. Technician A says this could be cause by faulty proportioning valve. Technician B says this could be caused by a faulty brake booster. Who is correct? a. A only b. B only c. Both A & B d. Neither A or B A : A only why : tech A is correct. a faulty proportioning valve could cause the pressure to the rear wheels to be too high and lock the wheels during hard braking There is a loud growling noise only when the vehicle is steered to the right while driving. Which of the following could be the cause? a. work left front brakes b. worn wheel bearing c. worn right front brakes d. sticking brake caliper B : worn wheel bearing why : this is a typical wheel bearing noise A spongy pedal can be the result of: a. leaking wheel cylinders b. broken return springs c. contaminated linings d. seized wheel cylinder pistons A : leaking wheel cylinders why : a spongy pedal can result from air in the hydraulic system. leaking wheel cylinders could allow air to get into the hydraulic system and result in a spongy pedal A vehicle has a wheel speed sensor diagnostic trouble code. Which of the following is the LEAST LIKELY cause?
