ASE A5 Brakes Practice Test -Section 1- Hydraulic System DIagnosis and Repair Exam Questions and Answers

ASE A5 Brakes Practice Test -Section 1- Hydraulic System DIagnosis and Repair Exam Questions and Answers A spongy brake pedal may be caused by: - Ans:-Air in the hydraulic system d - Air causes a gap in the hydraulic fluid flow because the fluid has to compress the air before it can apply the piston. This delay causes the spongy feel. The other choices do not affect this concern. This question is not like the others. It has the word EXCEPT. For this question, look for the choice that could NOT cause the described situation. Read the entire question carefully before choosing your answer. A vehicle has a very erratic brake pulling concern while applying the brakes. All of the following items could cause this erratic pull EXCEPT: Excessive tire pressure b. Four-wheel alignment c. Seized caliper piston on the other side d. Steering gear problem - Ans:-a. Excessive tire pressure ©GRACEAMELIA 2024/2025 ACADEMIC YEAR. ALL RIGHTS RESERVED FIRST PUBLISH OCTOBER 2024 Page 2/10 Excessive tire pressure is the exception because this fault will cause tire wear but not a pull. Low or uneven tire pressure can cause a pull. 3. The brakes are being bled on an older vehicle equipped with a quick take up valve in the master cylinder. Technician A says the quick take up valve must be depressed. Technician B says the brakes on this vehicle cannot be bled. Who is right? - Ans:-Neither A nor B - Both technicians are wrong. The brakes on quick take up systems use the same bleeding procedure as those without this valve. A power assist brake booster push rod that is to short will cause which of the following? - Ans:- Excessive brake pedal travel - A short push rod length will have to travel farther for contact and result in excessive pedal travel. This question is not like the others. It has the word EXCEPT. For this question, look for the choice that could NOT cause the described situation. Read the entire question carefully before choosing your answer. Excessive brake pedal travel with a firm brake pedal can be caused by all of the following issues, EXCEPT: - Ans:-Low brake fluid level ©GRACEAMELIA 2024/2025 ACADEMIC YEAR. ALL RIGHTS RESERVED FIRST PUBLISH OCTOBER 2024 Page 3/10 A low brake fluid level will not cause excessive brake pedal travel and a firm brake pedal. All of the others will cause excessive brake pedal travel and a firm brake pedal The master cylinder fluid level is low on a vehicle. Technician A says the cause could be a brake out of adjustment. Technician B says that one of the brake systems has failed. Who is right? - Ans:-Both A and B - Technician A is right because blockage of the compensation ports will not allow the fluid to return to the master cylinder reservoir and thereby cause the brakes to remain applied and drag. Excessive free travel cause brake lag not drag After the replacement of a master cylinder the brakes drag. Technician A says the compensation ports may be blocked. Technician B says excessive pedal free play could be the cause. Who is right? - Ans:- Technician A is right because blockage of the compensation ports will not allow the fluid to return to the master cylinder reservoir and thereby cause the brakes to remain applied and drag. Excessive free travel cause brake lag not drag. Technician A says a brake fluid leak at the rear of the master cylinder can leak fluid into the master cylinder. Technician B says oil leaks can be found by adding a dye to brake fluid that is visible under ultraviolet or black light. Who is right? - Ans:-Both A and B ©GRACEAMELIA 2024/2025 ACADEMIC YEAR. ALL RIGHTS RESERVED FIRST PUBLISH OCTOBER 2024 Page 4/10 A master cylinder has been replaced. In an overall bleeding sequence, which part should be bled first? - Ans:-Master cylinder The master cylinder is always bled first and the wheels in order from the one farthest from the master cylinder. Two technicians are describing master cylinder characteristics. Technician A says it is NOT normal to see fluid movement in the reservoir when the brake pedal is depressed. Technician B says a defective master cylinder can cause the brake pedal to slowly sink to the floor when depresse
