Final answer:
Possible causes for the left front disc brake assembly to drag include a warped rotor, a stuck caliper, or a frozen slide pin.
Step-by-step explanation:
There are a few possible causes for the left front disc brake assembly to drag:
- Warped rotor: If the brake rotor is uneven or warped, it can cause the brake pads to constantly rub against it, resulting in dragging.
- Stuck caliper: The brake caliper may be sticking, preventing it from fully retracting and causing constant contact with the rotor.
- Frozen slide pin: If one of the slide pins that allow the caliper to move is frozen or seized, it can prevent the caliper from releasing, leading to dragging.
To diagnose the specific cause, a technician would need to inspect the brake assembly and perform tests to determine the exact issue.
