1. What is the maximum allowable clearance be- 0.06 inches
tween the clevis pin and the clevis collar?
2. What is the discard limit for most truck and Discard: 0.090"
trailer brake drums? Maximum: 0.120"
Minimum: 0.060"
3. All of the hardware mounted on an __________ Axle spider
should be inspected when performing a foun-
dation brake service.
4. S-camshafts should be inspected for ______ play, radial play; end play
_____ play, flat spots and twisted splines.
5. Insufficient brake pedal ______ freeplay can pushrod
force the master cylinder pistons forward
slightly, allowing the compensating ports to be
blocked. This can result in brake drag.
6. I misadjusted __________ switch can cause the stop light switch
brake lights to be on all the time, resulting in
battery drain.
7. The stop light switch is a normally _____ switch open; closed
that is ______ when the brakes are applied.
8. Which type of fluid is typically used in a hy- Power steering fluid
dro-boost brake booster?
9. The specification for the maximum dimension stamped into the drum
of a brake drum can be found:
10. proportional

A _________ braking system is one in which brak-
ing pressure reaches each actuator simluta-
neously
11. A _____-cylinder balanced air compressor does two-cylinder; single-cylinder
not have to be timed to the engine upon in-
stallation; however, a ______-cylinder compres-
sor does.
12. What happens when there is no air pressure in The primary piston travels in the
the primary brake circuit? bore and pushes the secondary pis-
ton to operate the secondary brakes;
this creates a low pedal feel.
13. The most likely cause of a swollen master cylin- petroleum-based lubricants.
der cap seal is contamination from ________.
14. Dirty brake fluid can plug the master cylinder fill and compensating ports.
____ and _______ ports, resulting in slow brake
applications and release times, as well as brake
failure.
15. A truck has a hard brake pedal. Which of the A failed brake booster
following is the most likely cause?
16. Two types of brake line tubing flares are used in International Organization for Stan-
trucks: _____________ (ISO) and _________. dardization; double flare
17. ISO brake line tubing flares use an _________ outward flare
18. Double flare brake line tubing flares create a double wall
________ at the nipple
