Understanding the Importance of Square Cut Seal in Brake System

Scenario Explanation

Technician A says fluid leaks from the caliper dust boot indicates a worn square cut seal. However, Technician B argues that the square cut seal acts as a self-adjustment mechanism in the brake system.

The square cut seal plays a crucial role in the brake system by keeping the brake fluid behind the piston and assisting in returning the pad to its original position. This self-adjustment method ensures the proper functioning of the brakes.

What is the scenario about?

Note that the square cut seal is responsible for maintaining the integrity of the brake system and facilitating self-adjustment. This component is essential for ensuring efficient braking performance.

Technician A vs. Technician B

Based on the scenario above, Technician A is incorrect in suggesting that fluid leaks indicate a worn square cut seal. On the other hand, Technician B's assertion about the square cut seal serving as a self-adjustment mechanism is accurate.

Question
