This type of lift supports the vehicle by its frame or designated lift points and leaves the wheels hanging free.
What is a two-post lift?
When working under a vehicle supported by jack stands, this should always be placed under a tire as a backup safety measure.
What is a wheel chock?

What is over-inflation?
What type of suspension component includes a shock absorber and coil spring in one unit?
What is a strut?
This type of brake system uses a floating caliper design that applies force to both sides of the rotor
What is a sliding caliper system?
This safety feature on hydraulic lifts prevents the vehicle from falling if hydraulic pressure is lost.
What are mechanical safety locks?
: When working with older brake systems that might contain asbestos, this type of personal protective equipment should be worn.

What is TPMS (Tire Pressure Monitoring System)?
What might excessive bouncing after hitting a bump indicate?
What are worn shocks or struts?
This condition occurs when brake rotors have thickness variations and causes a pulsation in the brake pedal.
What is disc thickness variation (or brake judder)?
When using a two-post lift, the vehicle's weight should be distributed with this percentage in front of the lift posts.

What is a star pattern (or crisscross pattern)?
Which alignment angle is affected when the tire leans inward or outward from the top?
What is camber?
In a diagonal split brake system, if the front-right brake circuit fails, which other brake will also lose hydraulic pressure?
What is the rear-left brake?
This type of lift is best for alignment work because it supports the vehicle at its wheels.
What is a four-post lift?
In case of a large battery acid spill, this substance should be used to neutralize the acid before cleanup.
