Answer :
Final answer:
Technician A is incorrect about using copper tubing for a brake line repair as brake lines are typically made from steel. Technician B correctly indicates the use of a tubing bender when fabricating new brake lines for proper fit and function. Therefore, only Technician B is correct in this scenario.
Explanation:
Understanding Hydraulic Brake Systems
In a hydraulic brake system, both technicians present valid points regarding the brake line repairs. A leaking brake line may be fixed using a new section of tubing, but it is crucial to consider the material. Technician A's statement about using copper tubing is not typically correct; instead, brake lines are usually made of steel or flexible rubber hose for safety and resilience.
On the other hand, Technician B correctly states that a tubing bender should be used when fabricating a new brake line. This tool ensures that the tubing is bent accurately to fit within the vehicle, allowing for optimal performance and preventing kinks that can impede the brake fluid flow. Thus, while both technicians have points, Technician B is correct regarding the necessity of the tubing bender.
