SOS BRAKE & BRAKING SYSTEM UPDATED
SCRIPT 2026 PRACTICE SOLUTIONS
GRADED A+
● What does brake fluid do? Answer: Links the braking system
components through the brake lines to connect the master cylinder to the
calipers and the wheel cylinders. Fights corrosion
● What are brake fluid contaminants? Answer: Moisture, dirt, and air
● How is a disc brake system different than a drum brake system?
Answer: The major difference between the systems is the hardware. Disc
brakes use rotors, pads, and calipers. Drum brakes use drums, shoes, and
wheel cylinders.
● What are the benefits of ABS? Answer: Prevents locking and is
designed to help maintain the traction, improving control and safety.
● What do the letters TCS represent? Answer: Traction Control System.
● How does TCS work? Answer: Uses sensors to detect tire slippage
during acceleration.
Adjusts throttle input and applies braking force to slow a slipping wheel
and help the tire regain traction with the road.
, ● What are the benefits of TCS? Answer: Helps tire regain traction and
stay on the road.
● What do the letters ESC represent? Answer: Electronic Stability
Control
● How does ESC work? Answer: Added to many vehicles to help drivers
maintain control during unstable situations such as attempting to avoid a
crash or during unfavorable weather conditions.
Required on all 2012 and later vehicles.
● What are the benefits of ESC? Answer: Helps the vehicle stay on the
intended course, lessening the chance of slidding and rollovers.
● What do the letters BAS represent? Answer: Brake Assist System
● How does BAS work? Answer: Detects attempted panic breaking
based on the force that is applied to the brake pedal and how fast the
driver is stepping on the pedal.
● What are the benefits of BAS? Answer: Provides additional brake
pressure to allow the Antilock Braking System which prevents wheel
lock up.
