Before you spend money on your car making it accelerate quicker it will be in your best interest to have the brakes done above anything else. The importance of having an effective braking system cannot be stressed enough. If words don’t get the message through there are graphic pictures that can paint an outcome for you of a result of the faulty or failing braking system. It is in the interest of safety for both yourself and your passengers that you have a braking system that is in optimum working condition. You will want that security knowing when you push the brake pedal that you are going to stop.
Do I Need To Replace Both Front And Rear Brake Pads At The Same Time?
When we take a closer look at how your braking system works it we get to the understanding that brake pads wear at different rates, this is completely normal. When you push the brake pedal in your car weight from the rear of the car is transferred to the front of the vehicle. With most of the weight being at the front end of the vehicle, this puts more load on your front brake pads. Naturally, as your front brake pads take more load than the rears do it comes as no surprise that your front brake pads will wear out sooner than the rears. It is very common to have pads replaced in pairs as is necessary.
Why Do Car Manufacturers Bias Brake Pressure?
For your car to stop effectively your tires need to be under load so that they can grip to the surface below them. As we discovered above weight is transferred from the rear to the front of the car. Because the front of the vehicle is under more load than the rear you can apply more brake pressure in the front than the rear. With the rear of the car exerting less load on the rear wheels you can’t apply the same amount of brake pressure for if you did the rear wheels would be sure to lock up under hard braking. Your brake pressure is controlled for you by a unit called the master cylinder that directs more brake fluid to the front of the car.
How Do Brake Pads Wear Down?
Your brake pads are an important component in the braking system without them you essentially wouldn’t be able to come to a stop. The system is comprised of a rotor which rotates with your wheels. When you step on the brake pedal your master cylinder pumps hydraulic fluid to the calipers that have pistons in them that push the pads against the rotor. When the pads are against the rotor this creates friction. It is in this process where through friction that minute layers of the pad will deteriorate over time, which is the cause of your pads wearing down.
When Is It Time To Replace My Pads?
Luckily manufacturers have engineered technology into brake pads that will give you distinct tell-tale signs as to when it is time or nearing the time to replace your brake pads. One of the very first indicators that you may come across is the screeching or squealing when you apply the brakes. The cause of this sound is from a metallic shim that is embedded in the pad. When the pad wears down to a certain point this shim becomes exposed and makes contact with your rotor causing a metallic screech. You can also visually inspect your pads if they are less than a quarter-inch they need to be replaced.
