You are cruising towards a line of cars waiting at the traffic lights.You apply the brakes and get a sound that, like fingernails on a chalkboard, causes goose bumps on your neck.

Like any other car, an annoying noise can be one of the first signs that something is wrong, or it can mean that nothing is amiss.It’s up to you to figure out which one quickly.Keep in mind that in most cases, continued noise, even after the brakes have been heated, indicates that maintenance is in order.To help determine whether a screaming brake is a simple nuisance or an ominous sign, here’s a fast track of disc brake action that starts with a foot on the brake pedal and ends with a stopped vehicle.

Automobile brake action

The pedals apply pressure to the hydraulic system that pushes the caliper pistons out of the calipers, touches the brake liners and presses them against the rotating brake rotor.Friction pad friction material contact on the rotor converts kinetic energy into heat and slows the vehicle.The obvious first step in sharp search is to eliminate serious system problems.Brakes don’t just fail – they get worse.One element of the system integrates the rest of the system with it over time.

Brake system wear

The most common example of deterioration is severe brake pad wear, which is a simple and inexpensive repair.The next part to wear is the brake rotor where the gasket collides when the brake is applied.

Brake pads that wear into their back plane leave grooves in the rotor, which is not a cheap way to repair them.To avoid the domino effect of wearing brake parts, check for excessive pad or shoe wear.Look for grease or grease on cushions or shoes, warped or nicked rotors or drums, misaligned or loose calipers and rough hub bearings.

Glass pads or rotors or sticky pistons can also be used on the watch.If there is rust or corrosion on the brake element, it may be a sign that the piston is stuck.If the mat or shoe is worn unevenly, side by side, the piston may also be a fault.Even after you and/or your mechanic have determined that your braking system is on tip, the screaming may sometimes continue out of pure car malfunction.All the trouble you get is peace of mind that the brakes are working more or less properly.

Reduce vehicle braking noise

Still, there are a few options to eliminate the noise.If you recently purchased a high-performance carbon metal brake pad, be aware that this material is prone to noise.

So you may have to endure the screams or go back to the original equipment mat.If you only scream when your brakes are hot, that’s normal.If you are using the brakes to control speed on a steep slope, you may want the engine to do the job by changing into a lower gear.

As the brakes heat up, they become noisy and less effective.If the noise is ejected before the vehicle comes to a complete stop, rather than screeching over the entire braking range, the cause may be the vibration of the brake vane relative to the rotor.

A set of brake pad damping pads can cure screams, but there is no guarantee.The damping pad is made of a self-adhesive fiber material glued to the back of the brake pad back plate.Some have a mushroom-shaped button spring in the center.The theory is that the pads and button springs buffer the vibrations and create extra clearance to reduce or completely eliminate the vibrations or screams.

Another solution to the mat vibration problem is a good coating against sharp compounds in the form of spray or liquid coating.These heat-resistant polymer adhesives are located on the back of the pad to cushion the caliper pistons.Be sure to apply it only to the back where it is in contact with the piston.

If it ends in the front contact area of the mat or shoe, the stop function of the component is reduced.The spray helps the pad retract from the piston and mute the scream.Another option to reduce vibration is to use a thin coating of a high-temperature anti-stick compound in the same area as the anti-sharp compound.

This is a less effective anti-sharp solution, but it also helps to replace brake pads more easily.Continue with the first two solutions unless you are using the vehicle on the track and moving quickly through the brake pads.Vibration damping pads or anti-sharp compounds cannot be guaranteed.When used together, they eliminate screams, or at least reduce them to a less irritating decibel level.
