A disc brake assembly includes the brake rotor, friction pads, and brake calipers. The brake rotor provides the friction surface for the brake pads. The rotor is mounted to an axle or hub and turns with the wheel, and the pads are mounted in the caliper that straddles the rotor. When the brakes are applied, hydraulic pressure forces the caliper piston(s) outward, in turn clamping the brake pads on both sides of the rotor, slowing and stopping the vehicle.

Disc brakes were originally developed for racing, and shortly afterward began appearing on production cars. By the 1970s, all cars and light trucks were equipped with disc brakes at the front wheels, and today most of these vehicles have them at all four wheels. When compared to drum brakes, disc brakes run cooler making them more resistant to fade, are self-adjusting without needing any additional mechanism, and less prone to pulling and grabbing.

Disc brakes naturally run cooler because their friction surface is exposed to the air, unlike the enclosed friction surface on drum brakes. Cooling is further improved on vented rotors that have cooling fins cast in between the friction surfaces. Solid rotors are used on small, non-performance cars, and some vehicles have vented rotors in front and solid rotors in rear. Most rotors are separate components sandwiched between the hub or axle and the wheel, but some are cast integral with the hub. Most rotors are made of cast iron, but some are composite, with a cast iron friction surface and steel center section.

Rotors can suffer from several defects that disqualifies them from further use. Visually inspect the friction surface for scoring and grooving caused by wear, dirt, or brake pad backing plate contact. Measure the rotor thickness. All rotors have minimum thickness, or discard, specifications that are usually cast or stamped into the rotor center section. A rotor that is too thin will not have the ability to dissipate heat, and could warp, crack or otherwise fail if used. Another rotor problem is excessive runout and thickness variation that can cause annoying pedal pulsation. Runout can be checked with a dial indicator.

It used to be common practice to machine rotors, but today’s rotors are very thin to save weight, and cutting them will only make them more prone to warpage, and scoring and grooving can be too deep to be removed without exceeding minimum thickness specifications. And some defects like heat checks and hard spots can’t be machined away. For an effective, long lasting repair, your best course of action is to install new brake rotors, and always in pairs per axle. We have a large selection of replacement rotors made to OE specifications for metallurgy and surface finish, for smooth, quiet braking performance.

    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".

    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.

    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.

    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.

    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.

    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.
