If you are embarrassed to engage your brakes because of loud squealing, consider taking your vehicle to the repair shop like BST Performance Automotive Ltd and getting them checked out. The brakes on your vehicle need to be maintained just like the rest of the vehicle and the following problems may be why your brakes are singing to you.  

Worn Down Brake Pads

If your brake pads are worn down, the metal on metal rubbing will sound like squealing when you engage your brakes. The rotor and brake disc are not supposed to touch each other and when they do, you may notice your vehicle's brakes smoking a little too.

Low Quality Brake Pads

If you place low quality brake pads on your vehicle, you will notice a higher level of squealing than with higher quality pads. This is because the low quality metal used create more friction and as you press down on the brakes the metal touches your metal rotors creating the noise.

Grooves in the Rotor

When your rotor is damaged due to metal on metal rubbing, you will hear a squeal when you press down on your brakes. Your rotors are also responsible for a squealing vehicle when the rotor itself is not cut correctly or is glazed.

If your brake pad stays in contact with the rotor longer than it needs to while the vehicle moves, the action creates heat and friction which leads to premature brake pad wear.

No Insulation Shims Applied

The shims on your vehicle are in place near the brake pad to insulate and absorb additional heat from the friction of the brake pads. When the shims are properly installed and working, your vehicle will not squeal when you try to stop.

If you do notice squealing, it is possible the shims are worn down or when your vehicle had its last brake pad change, new shims were not placed on the vehicle.

Weather Plays a Role

The weather plays a role in whether your brakes squeal. If you are driving during wet weather or you go through a puddle, your brakes will squeal for a little while until the brake pads dry out again. Sand and humidity cause squealing problems as well.

Most brake squealing is caused by the weather, worn brake pads, and grooves carved into the rotor. With the proper automotive maintenance plan in place, you can avoid all of these brake squealing problems. While some squealing is normal, there could be an underlying condition that needs to be addressed. Since your brakes are the only thing stopping your vehicle, you do not want to push off repairs until later.
