Questions We Hear a Lot

1. Is it safe to drive with the brake pad warning light on?

Resetting the light without replacing the worn pads will only temporarily silence the warning. It’s essential to address the underlying issue by replacing the pads to ensure proper braking function.

4. What are the signs of worn brake pads?

Besides the warning light, other signs include:

• A grinding or squealing noise when braking.
• A spongy or soft brake pedal.
• A longer stopping distance.
• Visible wear on the brake pads themselves.

5. Can I reset the brake pad warning light myself, or should I take it to a mechanic?

While resetting the light is a relatively simple DIY task, replacing the brake pads is a more complex procedure that may require specialized tools and expertise. If you’re not comfortable with automotive repairs, it’s best to take your BMW X5 to a qualified mechanic.
