Understanding the Sprinter Brake Pad Warning Light
The Sprinter brake pad warning light, often depicted as a brake caliper with an exclamation mark, indicates a potential problem with the vehicle’s braking system.

Diagnosing the specific cause of the Sprinter brake pad warning light requires a thorough inspection. It’s best to take your vehicle to a qualified mechanic for a comprehensive diagnosis.
Here’s what a mechanic might do during the diagnosis:
