21. Two technicians are discussing master cylinder residual check valves. Technician A says the check valve is used on four wheel disc brake systems. Technician B says the valve maintains pressure when the brakes are released. Who is correct? A. Technician A B. Technician B C. Both Technician A and B D. Neither Technician A or B |
26. Technician A says that floating calipers use pins for caliper movement during brake application. Technician B says fixed calipers have pistons on both sides of the rotor. Who is correct? |
22. Technician A says accumulators are found only on non-integral ABS systems. Technician B says the ABS system works independently of the basic braking system and needs its own source of hydraulic pressure. Who is correct? A. Technician A B. Technician B C. Both Technician A and B D. Neither Technician A or B |
27. Technician A says master cylinder fluid level sensors activate a yellow brake indicator lamp when the fluid drops below a specified level. Technician B says brake pad wear sensors light a dash lamp when the bare wire contacts the brake rotor. Who is correct? |
23. Technician A says permanent magnet wheel speed sensors produce AC voltage. Technician B says the sensor is placed close to a toothed ring located on the axle or hub. Who is correct? A. Technician A B. Technician B C. Both Technician A and B D. Neither Technician A or B |
28. Which of these is not part of an integrated ABS unit. |
24. Which statement is true about quick take-up master cylinders. A. They have a quick take-up valve located between the reservoir and the secondary piston. B. They have a smaller diameter primary piston. C. They utilize low volumes of fluid. D. It is a step bore master cylinder with a fast fill valve. |
29. A three-function combination valve has all of these except: |
25. Technician A says the air valve of a vacuum brake booster controls the vacuum side of the vacuum diaphragm. Technician B says power piston controls the air valve in a vacuum operated brake booster. Who is correct? A. Technician A B. Technician B C. Both Technician A and B D. Neither Technician A or B |
30. A hydro-boost brake system has reduced braking performance. Technician A says to check the power steering system. Technician B says to check the vacuum check valve. Who is correct? |
