• Failed wheel speed sensor

• Worn brake pads

• Worn brake shoes

All of the following can cause a low brake pedal EXCEPT:

• frozen automatic adjuster

• plugged/clogged brake line

A brake drum that is out of round can cause:

• Low brake pedal

When the engine is started, the brake pedal drops slightly. This would indicate:

• A failed check valve

• Too much vacuum

• Normal operation

• Failed brake booster

Over torqued or unevenly torqued lug nuts can cause what type of issues?

• vibration while braking (pulsation)

• uneven brake pad wear

• low brake pedal

When bleeding brakes on a vehicle, a technician should always do all of the following EXCEPT:
