ASE A5 Brakes Certification Competency Exam Study Guide Comprehensive Resource To Help You Ace Includes Frequently Tested Questions With ELABORATED 100% Correct COMPLETE SOLUTIONS Guaranteed Pass First Attempt!! Current Update!! 1. Which of the following should be used to clean the bores on wheel cylinders? a. cleaning solvent b. oil soap c. hot water d. denture alcohol - Correct Answer: D. denture alcohol used only to clean bores of wheel cylinders 2. All of the following about brake hoses are true EXCEPT: a. Some Caliper components and hoses may be reverse threaded b. most hoses are attached to the chassis secured with a hose lock clip c. cleaning the ends of the hoses prior to removal will reduce the possibility of dirt entering the system d. replacement hoses can be longer than the original - Correct Answer: d. replacement hoses can be longer than the original, hose should always match the length of the original equipment. any chance of hose rubbing would cause a problem. -cleaning ends is a good practice, but will not cause a problem -some caliper components can be reverse threaded. 3. A vehicle demonstrates brake drag. Tech A says fluid may be leaking past the master cylinder cups. Tech B says the stop light and cruise control switch may require adjusting. who is right? a. Tech A only b. Tech B only c. Both A and B d. Neither Techs - Correct Answer: B. Tech B only, a mis adjusted stoplight or cruise control disable switch could cause brakes to drag preventing full release of the brakes. - Fluid leaking past the master cylinder would cause spongy and possibly shrinking pedal. 4. During the teardown phase of a brake job, the technician discovers the front wheel bearings are badly damaged as a result of incorrect adjustment. Which brake pedal complaint would have lead to the teardown a. Spongy b. Hard c. Rising d. Pulsating - Correct Answer: D. excessive end play would cause brake pulsations. -Spongy pedal causes by air in the system -Hard pedal caused by lack of power assist or glazed pads 5. On an ABS with high-pressure accumulator, the accumulator is depressed by: a. pumping the brake pedal 25 to 40 times with the ignition switch off b. pumping the brake pedal 10 times with the ignition switch on c. loosening the bleeder screw on the accumulator with the ignition switch on. d. Loosening the front wheel bleeder screws with the ignition switch on. - Correct Answer:- a. pumping the brake pedal 25 to 40 times with the ignition switch off. - loosening any part of the brake system could be dangerous. with the ignition switch on builds up the back pressure 6. When making final adjustments on the drum brakes the star adjuster should be adjusted: a. until there is a slight drag on the wheel b. until the shoes hold the wheel firmly in place and then backed off until there is a slight drag c. until there is a slight drag on the drum and then backed off until the wheel spins freely d. one full turn to back the shoes further away from the drum - Correct Answer: c. until there is a slight drag on the drum and then backed off until the wheel spins freely. -slight drag would cause the wheel to overheat and wear premature 7. The rear wheels lock up too quickly during heavy braking on a vehicle with front disc/ rear drums brakes. Which of these is the MOST likely cause? a. Air trapped in the master cylinder b. faulty metering valve c. defective brake booster d. malfunctioning proportioning valve - Correct Answer: d. malfunctioning proportioning valve trapped air caused low spongy pedal, a faulty metering valve cause nose diving and front wheel lock up. defective booster causes excessive pedal effort. -REMEMBER DIFFERENCE BETWEEN Proportioning valve / metering valve 8. All four wheels spin freely on a rear-wheel vehicle that is raised off the ground. The brake pedal is depressed momentarily, then released. All wheels now spin freely except for the right front. The cause of the problem could be a: a. faulty proportioning valve b. missing flex hose sealing washer c. seized equalizer d. restricted flex hose - Correct Answer: d. restricted flex hose, may force the hydraulic fluid pressure through the flex hose then apply the brakes, but may retain fluid pressure when pedal is released. -proportioning valve would only effect rear brake applications -missing sealer would cause brake fluid leak -seized equilizer would cause proper brake adjustment 9. After installing a bench-bled master cylinder, Tech A says the entire system should be bled. Tech B says the system is ready for operation because the lines were capped. who is right? a. A only b. B only c. Both A and B d. Neither A nor B - Correct Answer: a. A only, all bench bleeding accomplished is removal of air from master cylinder (must always bled system when air can be introduced into the system) 10. On a single piston floating calliper, the inside brake pad lining is worn out, but there is little wear on the outside pad. The cause of problem could be? a. A worn calliper pin and brushing b. A leaking calliper piston seal c. a leaking brake hose d. excessive rotor lateral runout - Correct Answer: a. A worn calliper pin and brushing -leaking piston seal would cause fluid loss in the system -Leaking brake hose would cause fluid loss - excessive lateral rotor run out would cause pedal pulsation
