Let's say you went down a hill Mountain Pass.

You use your brakes quite a bit.

You are pulling a trailer.

You were using the brakes in some cases could be normal, but in other cases it could indicate really serious problem that can guys cause more trouble and maybe it can cause even lots of breaks, so never ignore that we'll explain what to look for guys, so all that will be covered today before we start.

Let me just tell you a little bit about us guys.

Every single car we get here at the garage we try to make at least two to three hundred free repair videos.

While we do that because our mission, the shop, is to save you as much money as we can all.

We need guys in return, Please Subscribe to the channel, like the video that way, we can keep making this absolutely free videos, guys we're constantly getting new cars here in the garage working on that BMW.

Now we got a DOT Challenger that will be working.

We have more than 15 Vehicles waiting to be shot guys, so videos are coming all the time if you need help with anything, leave a comment below our videos and we'll try to make a video for your problem.

That way we can help you.

We can help other people without problem and we can build a community where we help each other.

If you need to buy any parts tools for your car, they're, really good price and quick shipping check out the link in the description of the video below.

That's where we get all our two supplies from guys and you can save a ton of money, so we've demonstrated here on that BMW guys.

Let's say we will explain a few scenarios: you're driving, okay, maybe throw a melting pass.

Okay, you're using your brakes! Quite a bit.

You stop, say the terminal, the scenic pass gas station.

Anything like that guys! You stop and you smell burning smell from the wheels that could be in some cases normal from excessive use of your brakes, because they can be getting really hot, but in other cases it could indicate a problem as well.

In some cases it could be most of the times.

Okay on the phone.

You will notice it or it could be individual.

We own the car anywhere.

Why we say the phone usually will be normal, because, if use your brakes a lot most of the braking power will go to the front wheels in a little bit less to the rear, because the rear of your vehicle is usually lighter and it's made to wear.

Most of the braking power goes to the foam, but talking about right now, guys, okay, it could be anywhere that has that burning, hot smell coming off of it and what can sometimes cause that, if it's not normal, you use excessive use of breaks.

It could be guys.

Okay, in some cases, if you have glazed brake pads check out this brake part right here, that's really old and a hard, and it's been exposed to a lot of heat, it's practically bubbling, which makes it really hard.

It has that glazed mirror finish.

The roller itself too.

That will require extra friction.

Extra force and I will create extra friction to slow you down, which will release more heat, so old, Parts, Old brakes and glazed roller skin easily, because that that's why it's recommended every time you replace the brake pads, you need to either replace the disc rollers or resurface them if they are thick enough guys in it safe to do so now something else that can cause okay, that smell it could be guys sees the brakes because you're driving it could happen on flat or even going uphill.

Without using the brakes you slow down.

You stop one of the wheels.

Here's that hot burning smell, it is very likely we have seized uh brakes guys that can be caused by multiple things.

In some cases it could be something simple, such as the caliper Glides right here, the pins that allow the caliper to move left and right.

Those are supposed to be replaced guys on most Vehicles when you do brakes, they're very inexpensive, but sometimes they can be arrested.

They can have build up that will not allow them to move and, as a result, the brake caliper may not Center itself and you may have dragging brakes another thing that can cause that guys, okay, having a seized up brake caliper, could be the Piston being seized up here.

That means that the Piston, when you apply the brakes, that piston will expand, so it will put pressure on the brake pads and that will put pressure on the disc and you start slowing down.

But when you release the brake paddle, that piston will go by about half a millimeter in from the vacuum, so you will release the pressure of the brakes that way.

But if that piston, he sees that it will not go back in, it will just come out stay there and that can cause pressure guys and that will cause you that breaks all seized up.

Caliper piston will cause that will have a video on the channel.

That will explain how to fix.

Seize the brake caliper everything from start to finish on the channel check it out.

It will teach you how to do that.

Those are some of the most common things we see guys now.

In other cases, if you guys went through a mountain pass or use your brakes excessively and you notice that brakes started like the steering wheel started shaking when you apply brakes.

Brake paddles start pulsating.

That means that you have a disc brake roller.

That's not even it's not straight As a result.

You have low and high spots and that can affect the stopping power as well, because the brake pads will not be able to follow guys practically the uneven surface of the road that will cause brake pulsation and you have limited stopping power, because only half of the disk practically will be working as a result that can start overheating our brakes and that can cause that burning smell as well, but never ignore it guys.

We recommend to get a heat gun uh when you slow down check the front.

The wheels need to be at about the same speed the brakes and the rear.

Wheels need to be about the same speed, left and right side and front left and front right as well need to be about matching.

In some cases it could be a bad bearing wheel bearing, but that it does happen, but usually most of the times will be brakes if, let's say you're driving your vehicle, we haven't used your brakes and you still have that burning smell.

When you stop, it could be better wheel bearing you can check the temperature of the bearing with a heat gun and compare it to the other side, and if it's way harder, that's your problem.

Hopefully the video will be helpful to any of you needing that information.

Thank you for watching and see you next time.
