(Episode II) Brake Noise and Pulsation Isn’t Just Annoying—It’s a Warning
I had a lot of fun making this one. I even managed to through in a few funnies. I may have gone over some of the topics twice, but they are twice as important. Squealing? Grinding? Clicking? If your brakes are making noise, your car is trying to tell you something. In this video, we break down the most common types of brake noise, what they mean, and when it’s time to take action.
🔧 What you’ll learn:
Common brake noises and what causes them
Squeaky brakes vs grinding brakes – big difference
When brake noise is normal (and when it’s not)
How weather, dust, and rust can affect noise
Why cheap pads can make more noise
What a clicking or clunking sound might mean
How to prevent premature brake wear and noise
Real-world examples from our shop floor
Whether you’re driving a Subaru, Toyota, Honda, Ford, Chevy, or any vehicle, this video helps you understand which sounds mean safety issues—and which ones are just annoying.
⚠️ Ignoring the wrong sound can cost you your brakes—and your safety.
