If your brakes are squealing, squeaking, or making a noise every time you stop, don't just turn up the radio and hope it goes away.

Our ASE Certified Mechanic Will says it's time to get those brakes checked out! 🛠

Brake noise can be a sign that your pads are getting worn or that something else needs attention. Catching a problem early can help prevent a small repair from turning into a much bigger one.

Hear the squeal? Bring it in. We'll take a look!

Planning a road trip? Before you load up the car and hit the highway, Joe, Western Mountain's Head ASE Certified Mechanic, has one important piece of advice: check your fluids and make sure you don't have any active leaks.

In this episode of Ask a Mechanic, Joe explains why checking your vehicle's fluid levels—and looking for signs of leaks—can help prevent unexpected problems while you're on the road.

Before you hit the road, check:

Oil level
Coolant
Brake fluid
Transmission fluid
Power steering fluid
Washer fluid
And, most importantly, make sure you're not losing any of them!

A few minutes checking your vehicle before a trip could save you from a much bigger headache later.

Have a question for Joe? Drop it in the comments for our next Ask a Mechanic video!
