Question 1

What does it mean when your vehicle's brake pedal feels spongy or goes to the floor?

Accepted Answer

Air is in the brake lines or brake fluid is low

Answer

Air in the hydraulic brake lines compresses unlike fluid, causing a spongy pedal that reduces braking effectiveness.

Question 2

What minimum tire tread depth is generally required in most U.S. states before a tire is considered unsafe?

Accepted Answer

2/32 inch

Answer

Most states legally require at least 2/32 inch of tread depth, which is the wear indicator bar level.

Question 3

What does white smoke from the exhaust typically indicate?

Accepted Answer

Coolant burning in the combustion chamber

Answer

White smoke often signals a blown head gasket allowing coolant to enter and burn in the cylinders.

Question 4

How often should a vehicle's serpentine belt typically be inspected?

Accepted Answer

Every oil change or at least annually
