Hi, the grinding noise coming from the rear brakes is either the shoes have worn out & are down to the metal, or the drums havn't been removed for a long time and are full of brake dust / rust etc.
Change your brake rotor and brakes. problem solve
Maybe it's coming from the rear brakes.
The grinding noise is the brakes pads proably the noise is in the front. The front brake pads are easy to replace and is a do it yourself sort of thing. My guess is your brake light is coming on because of this condition. I assume your brake light has been coming on for a little while now.
It depends on where the grinding noise is coming from. Most of the time the grinding is coming from the brakes and the brake pads need to be replaced. If they've been grinding for a while, the rotors will need to be resurfaced or replaced. Other possibilities for grinding are worn axle bearings, or a problem with the clutch. If the clutch goes out, there will be a grinding noise when you try to shift gears.
The brake pads are worn out and need to be replaced. The grinding sound means your brakes are about to stop working.
sounds like brakes are metal to metal, that is, brake lining is completely worn out, and is grinding rotor.Ans 2 - You need a complete and thorough brake job. You have neglected to check things periodically ( things that your life depends on ) Expect to pay big bucks for the necessary work.
Brake pads up to 40k depending o how you drive and use your brakes. Rotors closer to 80k depending on your braking style. Listen for squeaking when braking, and pulsating while braking, as well as watch for your brake warning light coming on the dash. Any of this will tell you your brakes need servicing.
When this is happening, it may mean that they brakes are going out. This also means that the brake drums or rotors may be warped or not round anymore.
When you're brake pads be calm worn, they will have a slight shimmy when you apply the brakes. When the brake pads are completely worn out they will make a grinding noise.
Master Cylinder low of brake fluid, grinding when the brakes are applied, and long brake pedal travel on a vehicle with brake shoes instead of brake pads.
If your brakes are grinding at all, you need to inspect the brake pads. I suspect you will find your pads are worn out.
If your brakes are making a squeaking or a grinding noise when you are coming to a stop this is usually an indicator that your brake pads need to be replaced. Also, another sign that your brakes need to be replaced would be if your brake pedal goes all the way to the floor when pressed and it seems to be taking longer to stop.
