Why do I hear a scraping noise when I brake?

Why does my Jeep Wrangler squeak when I brake?
The most common cause for brake noise is thinning pads. If you hear a grind or loud shrill, you’ve likely worn your pads down. Because the brake pads are worn down, the pads and rotors are now metal to metal. At this point, it is imperative to replace them.
What causes brake groan?
Brake moans are typically caused by moisture built up in drum brake assemblies. When the brake shoes contact the drums during light braking, the moisture causes a moaning sound. A metal-on-metal noise when you’re braking means your brake pads are worn out completely (See Figure 2).
What causes brake noise?
When the pads and shoes wear down, it can result in a metallic grinding noise, as the backing plate starts making contact with the rotor or drum. Brake pads also have a metal wear indicator that drags on the rotors when the pads are worn out. This will make a grinding or squealing noise.
How do you fix squeaky brakes on a Jeep?
Squeaky disc brakes are not caused by glazed pads or warped rotors. The noise is vibration caused by the pad moving in the caliper. Applying anti-squeek compound like CRC’s ‘Disc Brake Quiet’ between the pad and caliper will cure the problem.

Excessive vibration is the leading cause of brake noise. While a certain amount of vibration is normal during braking, excessive vibration will cause abnormal brake noise.
