HI. If the sound is a metal to metal sound(piercing), this will be caused by the brake warning tabs on the brake pads. This is there to warn you of brake pad ware. You will need to schedule a brake job soon. you will need new pads very soon. This will occur upon pressing the brake pedal to stop the vehicle. Once the pads ware down to the tabs, they will make contact with the rotor and emit a piercing screech to warn you of the issue. Simply replacing the pads will correct the problem.

Now, if the rotors are red hot and you are hearing a grinding noise, this will be brake drag. You will need to have the entire brake assembly inspected for issues with the lines and calipers.

Concerning the brake fluid:

Brake fluid can be monitored by checking the brake reservoir under your hood on the left or right side of the engine compartment(depending on your orientation to the motor). This reservoir will be mounted in front of the master cylinder and is usually a plastic cup with a black top. If that reservoir is below specifications, re fill to specs. Low fluid will not necessarily cause noise. it will cause a loose of pressure, thus not allowing you to press and apply the brakes as designed. Its a hydrylic system. No fluid equals no brakes.

Check the reservoir under the hood.

The brakes making noise has nothing to do with fluid level, though.

There's a good chance your brakes are glazed from overheating or they are in need of replacement. There are sometimes pieces of metal which rub the rotor and make a loud squealing noise when you press the brake - they're wear indicators.

What is causing the loud howling from my 2002 Suburban?

Hello I don't know exactly where you live however, I'd say the loud " roaring noise is possibly the clutch fan. The reason why they are so loud and make the roaring sound is because as you accelerate the fan blades spread outward but are under resistance .It's activated by ambient engine temp. They are very noisy when engaged and tend to work more on rural roads, stop and go and when A/C is being used. etc. The brake light is on because the fluid is below the fluid level sensor basically telling you to check and or add brake fluid. In addition the ABS light has came on because it had ran low on brake fluid sending a warning signal to the computer from the ABS brake control module. The best thing to do is to keep up on the fluid level find that leak and repair it.

Loud noise rear driver side tire

If it is really loud rubbing sound, its either brake pads or could be your rotors. Typically these do not wear out at the same time. Defintely have them checked out, but before going anywhere, make sure to check your brake fluid level as it may be low on fluid that is necessary to apply the brakes and their functionality is dependent upon it.

What would cause loud idling sound , jerking motion and unresponsive brakes to a 2001 audi tt (manual transmission) after adding brake fluid?

loud idling may be higher rpm's and unresponsive brakes point to a vacuum leak in the power booster hose that will run very clos to the reservoir.

I have a 1994 Roadmaster. Brakes were fine yesterday. This morning brakes need pushed to the floor to stop and they make a LOUD grinding sound. How much for brakes or is it the brakes?

Don't drive the car, it's too dangerous! 1st check the fluid level. For the brakes to go to the floor, you must have a fluid leak somewhere. Any drips or puddles under the car? The grinding sound most likely indicates the brake pads are down to metal, and would explain the noise you hear. So, yes, it is the brakes, but as far as how much, a visual inspection is needed, as well as checking rotors for thickness to determine if they can be cut and used again, or if new ones are needed. Calipers need to be checked to make sure they are operating properly. If one is hanging up (not fully releasing), it could result in advanced wear to just one wheel. Always change brakes in sets, that is both front, both rear, or all 4 at once. Bleed the system well enough to flush out all lines, as old brake fluid can damage brake calipers and cylinders causing premature failure. The visual inspection will determine if you need calipers, pads, rotors, and how many wheels need new brakes. Good luck.

'96 Toyota 4-Runner makes a loud squealing noise and brake light

Sounds like one of the auxillary belts slipping it may just need tightening up. I think the 4-Runner has two belts one large and one for the steering pump

Loud low hum coming from the front of the car when accelerating. The handbrake/brake fluid light occasionally flickers on as I'm driving too. I recently hit the curb quite ******* the front left wheel. Do...

Hi ea
Im dave

The loud low hum sounds like a wheel bearing although i cant actually hear it. Does the sound get louder on right turns? Brake light coming on usually means low fluid check your fluid resorvoir if it below the max mark fill to the max mark. If it has run dry you probably need to bleed your brakes. The light however could mean your handbrake isnt fully released. Be sure it is all the way off if fluid level is adequate and the positioning of the cable is not kinked somewhere under the handbrake.
