#32- While assembling the brake shoes and related hardware:

• The secondary shoe faces toward the front of the vehicle.
• The primary and secondary shoe return springs are interchangeable.
• The adjuster must be installed in the proper direction.
• The adjuster cable is usually mounted on the primary shoe.

#33- Technician A says the brake shoes shown in the figure are being adjusted to match the brake drum size. Technician B says the brake shoes are being measured for wear. Who is right?

• Technician A
• Technician B
• Both A and B
• Neither A nor B

#34- When making final adjustments on the drum brakes:

• The star adjuster should be adjusted until there is a slight drag on the wheel.
• The star adjuster should be adjusted until the shoes hold the wheel firmly in place and then backed off until there is a slight drag on the wheel.
• The star adjuster should be adjusted until there is a slight drag on the drum and then backed off until the wheels spin freely.
• The star adjuster should be adjusted one full turn to back the shoes further away from the drum.

#36 Excessive brake pedal pulsation is experienced when braking. Technician A says the outer constant velocity joint may be worn. Technician B says the front wheel bearing may be worn and loose. Who is right?

• A only
• B only
• Both A and B
• Neither A nor B

After a brake application, the caliper piston is returned by:

• the twisting action of the seal
• a return spring
• brake fluid pressure
• atmospheric pressure

On a single piston floating caliper, the inside brake pad lining is worn out, but there is very little wear on the outside pad lining. The cause of the problem could be:

• worn caliper pins and bushings
• a leaking caliper piston seal
• a leaking brake hose
• excessive rotor lateral runout

#39- On a vehicle with front disc and rear drum brakes, a scraping noise is present in one front wheel while braking. The cause of this problem could be:

• worn caliper pins and bushings
• the pad wear sensor contacting the rotor
• loose caliper mounting bolts
• a loose pad mounting in the caliper

#40- After honing a brake caliper, the maximum allowable increase in caliper bore diameter is:

• 0.001 in (0.025 mm)
• 0.002 in (0.050 mm)
• 0.005 (0.127 mm)
• 0.008 in (0.043 mm)
