Because of the brake system, you can slow your vehicle and bring it to a complete stop in a safe, controlled and predictable manner. In this system, friction created by pressing stationary pads and shoes against rotors and drums that rotate with the wheels converts the vehicle’s kinetic energy into heat. Fluid in a hydraulic system multiplies the force applied by your foot on the brake pedal to apply the pads and shoes against the rotors and drums.

Most vehicles today have four-wheel disc brakes and pads are available in Non-Asbestos Organic (NAO), semi-metallic and ceramic formulations. NAO pads are made from organic materials like glass and rubber. They are softer, generally wear faster and create a lot of brake dust. Semi-metallic pads contain a large amount of metal fibers like steel. They are durable and great for high temperature applications, but they are tough on rotors and can be noisy. Ceramic compounds have ceramic fibers and softer metal fibers like copper. They provide excellent braking, with little noise, and less dusting and rotor wear.

No matter the type of pad used, eventually brake rotors wear out and must be replaced. As rotors wear they become thinner, and if allowed to wear below their minimum thickness they will no longer be able to dissipate heat properly, and can become warped or even cracked. Rotors can also become grooved if the pads wear to the point the rivets or backing plate grind the rotor surface. Brake rotor metallurgy and design can vary according to application. Cast iron rotors can be one-piece or have a stamped steel center section. Some replacement rotors are available drilled and/or slotted to help shed water and heat.

The brake hydraulic system includes the master cylinder, the calipers and wheel cylinders that apply the pads and shoes, and the interconnecting metal lines and rubber hoses. The master cylinder converts mechanical force into hydraulic pressure using pistons and seals in a housing usually made of aluminum, with a plastic fluid reservoir mounted on top. The calipers are mounted over the rotors and contain one or more pistons that apply the pads in response to hydraulic pressure. Vehicles with drum brakes have wheel cylinders with two pistons that force the shoes against the inside of the brake drums.

A leak in the hydraulic system can cause a low pedal and reduced braking. The master cylinder can leak but also fail internally. Failed calipers and wheel cylinders are usually evidenced by leaks, but calipers can also bind and cause pulling and uneven brake wear. Every time the vehicle brake system is serviced, the entire hydraulic system should be inspected. Corroded brake lines could eventually become perforated and leak, and brake hoses can deteriorate and crack from heat, exposure to chemicals and the elements. From pad changes to more serious repairs, we have the parts to keep your brake system in top shape.

In addition to the basic brake system, there is a mechanical parking brake system that applies the rear brakes independent of the hydraulic system, to keep the vehicle stationary when parked. Cables actuated by a foot pedal or hand lever apply the rear shoes or pads, or internal shoes within the rear rotors. Many vehicles have an electronic parking brake system. Most vehicles today also have an Anti-lock Brake System (ABS), which regulates fluid pressure to the wheels to avoid skidding and loss of control. The system includes a control module, hydraulic modulator, wheel speed sensors and toothed rings.

    Why is it important to do a brake fluid flush?
    If you've ever visited an automotive dealership service department, you may have been told that your vehicle needs a brake fluid flush. Or you might have received a coupon mailer offering this service for a discounted price. Maybe you thought it was an attempt on the part of the dealer to separate you from your money for something you don't really need. After all, you have made the effort to learn more about your brakes, and you understand that occasionally, the brake pads and rotors will wear out and need replacing. However, you've never heard of a "brake fluid flush".

    How To Replace Disc Brake Pads
    Disc brakes have been the most common setup on modern vehicles for decades, with just about 100% of today's vehicles using them in the front, and many cars and trucks also equipping the rear with disc brakes. The brake pads are the wear items which will need attention sooner or later; there will be wide variations in brake pad life depending on the vehicle, driver, driving style, etc., but rough estimates are that front pads will need attention every 15,000-30,000 miles, with rear disc pads lasting 50,000-100,000 miles.

    Glossary of Brake Terminology
    Whether you're looking to replace worn brake pads and rotors or delving into more detailed brake repairs or upgrades that involve new calipers, proportioning valves, master cylinders, vacuum boosters, and more, you will come across a lot of different terminology when it comes to brake components. Depending on your knowledge and experience, a lot of these terms may be elementary. However, because many of them use similar words but represent completely different things, we've created this glossary to help you understand exactly what you need, and what you don't.

    Disc Brakes and Drum Brakes Explained!
    If you have owned a car or truck for more than a few months, you are undoubtedly aware that your vehicle's brakes occasionally need replacing. Let's face it, we can be hard on our brakes. Highway speeds, stop-and-go traffic, and heavy cargo loads are some of the more significant factors which increase brake wear.

    Auto Parts: Dealer vs. Aftermarket
    The question of whether to buy parts from an automotive dealer vs. ones from aftermarket manufacturers is as age-old as the automobile itself. Below, we'll take a look at things worth considering to help you make a better choice if you're facing that same question. Automobile manufacturers and dealerships always advertise the fact that their parts are "genuine" because they were made by the exact same production facility that made the parts installed on the assembly line.

    Special Tools Used In Brake Service
    In this article, we’ll introduce you to the specific tools designed to be used when replacing brake components and servicing your brake system. Having the right tools BEFORE you start working on your vehicle makes these types of jobs quick, easy, and doable for the home mechanic. It also prevents having to put things back together before the job is finished because a tool needs to be purchased. Owning the right tools and doing the job yourself will save you hundreds of dollars by sparing you a visit to the repair shop – and much more over the course of a lifetime of brake work.

    Best Brake Rotors For Your Driving Style
    Disc brake rotors (aka 'rotors') are the actual discs that brake pads clamp onto, creating friction that slows a vehicle. Disc brake rotors bolt on over the axle hub and contain holes that allow wheel mounting bolts to pass through and rotate with the wheels. Since there are many rotor styles and designs specially created for every budget and need, we’ve listed the advantages of each disc brake rotor so that you can make the right choice and get the best for your vehicle. All rotors, except ceramic brake rotors and two-piece rotors with aluminum centers, are typically one piece and crafted from iron for maximum heat absorption.

    Is It Time For New Brakes?
    Squealing noise upon brake application is actually caused by a high-frequency vibration of metal rotors, drums, or brake pad backing plates. Excess corrosion that forms over time on non-contact, outer perimeter areas of rotors and drums is a prime cause because rust is looser and less dense in nature – therefore, more likely to create resonation.

    Tips To Get The Maximum Life Out Of Your Brake Parts
    If you've had to replace brake pads or rotors on modern vehicles, you know how expensive the parts and labor can be. Because extending your brake pad life puts real money back into your pocket, we offer some tips for those who are interested in doing just that. While it's a general rule that brake pads designed with aggressive grip levels and performance driving will result in faster wear, the following suggestions will help you extend your brake life significantly no matter what type of brakes you have on your vehicle.
