<human>: My friend has a problem with his car's brakes. How can I help him?
<bot>: One way to help your friend is to take the car to a mechanic and have them check the brakes. They may be able to identify any problems that need to be addressed, such as worn brake pads or a faulty caliper. If you're unsure of how to fix the issue, you could also suggest contacting a local auto repair shop for advice.
