If you’re having a high pitch squeal when you drive, should you stop driving and start freaking out? Naw. It is a warning sound that you should pay attention to, but it doesn’t mean your car is going to blow up or that aliens are about to land. Although, it does sort of sound like that last one. Here is what you need to know.
The High-Pitched Squeal
If the high-pitched squeal happens while you’re driving and goes away when you push on the brake pedal to slow down or stop the car, then it’s just a warning indicator that’s built into some brake pads. So, not to worry, it’s ok. But it is telling you that something is amiss. Your brake pads have worn down to the point where if you don’t replace them then it’s about to get expensive. So get that appointment on the calendar to have the mechanic at A1 Performance Auto Repair replace your brake pads.
But what if you just replaced the brakes?! If you hear the squeal when you’re braking instead of when you’re driving around, and you just had a brake job, it’s likely the brake pads. Some budget-priced brake pads are noisy when you brake. The only thing you can do is to have them replace the pads with ones that are quiet.
Another thing with just having a brake job is that the mechanic might not have lubricated all the spots that needed it. Or the pads and shoes are slightly out of adjustment. That doesn’t do any harm to the vehicle, but it will make an annoying noise. The best thing to do is to return to your mechanic to have them make adjustments and lubrication to stop the noise.
A1 Performance Auto Repair
When you want to avoid high-pitched squeals, have the mechanic at A1 Performance Auto Repair fix your brakes. We hope to see you soon.
There are a few reasons why your mechanic will tell you that it’s best to replace your bad rotors instead of having them machined. It isn’t that he’s making you buy unnecessary parts or doesn’t want the hassle of sending them out to be machined. There are some valid reasons why today you don’t have them machined.
A rotor is considered bad when it has grooves worn into it that are so deep it makes the brake pads wear out quickly. Up until rather recently, if you waited to change out your pads until they were completely worn down then you damaged the rotors, leaving grooves in it. Your mechanic would send your rotors to the machine shop and have them turned, smoothing out the surface so it is nearly brand new. That would allow you to get a long life out of your new brake pads and not get a bunch of noise when you braked. But things have changed and now they are either replaced or just left alone.
Rotors are made very thin these days and to machine them would greatly decrease their life. No good mechanic wants to charge their customer for a break job and then have them return in 20,000 miles to get another brake job. He won’t stay in business long doing that.
So, he’ll advise that you just replace the rotors along with the pads and any other parts that are worn out. Then everything is new and it’ll be a long time before you need another brake repair.
If your rotors are barely worn, he might suggest you just leave them as they are. You might hear a little minor squeaking, but it might be worth it to save a little cash. Usually, rotors are not just a little bit damaged, so this scenario doesn’t happen often.
Another issue with rotors is that these days it costs so much to machine them that you could have purchased new ones. So, your mechanic will just replace them.
Lastly, when a rotor is machined it doesn’t get that original proper finish, so it’ll make noise. And people hate it when they make a lot of noise after paying to have the brakes done.
So, be happy your mechanic opted to just replace those bad rotors.
