Car Brakes, Brake Parts, Rotors, Pads & More – Stop at BuyAutoParts.com for Superior Selection and Value
Your car’s brake system – rotors & pads, calipers & cylinders and other components – needs to work properly to ensure overall safety. When just one of those brake parts goes bad, your ability to slow down and stop is jeopardized.
Changing brake pads, rotors and other parts is fairly simple, once you’ve done it a few times. Even a casual car enthusiast can put new pads & rotors on, assuming they’ve got the right tools (and time) to get the job done. After oil changes, brake pad & rotor replacements are one of the most popular do-it-yourself projects for car owners. With mechanic labor rates increasing every year, the DIY option for changing brake rotors and pads offers money-saving benefits – especially when you purchase your brake parts at BuyAutoParts.com – and also the satisfaction of doing the job yourself!
BuyAutoParts.com has a great selection of brake parts for your car. You can browse our assortment of rotors, pads, cylinders, anti-lock braking system modules (ABS modules) and other parts based on your vehicle’s year, make and model.
To give you a better understanding of car brakes, let’s look at some key aspects of your brake system, including different parts, how they work together, certain safety mechanisms and other information that will help you decide which particular car brake parts you need.
Brake Pads and Rotors – The Front-Facing, Friction-Generating Part of Your Car’s Braking System
When most people think about a car’s brake system, the first two parts that come to mind are the brake pads and rotors. They’re also the most commonly replaced brake parts, partly because they’re responsible for generating the tremendous amount of friction and force that actually stop your vehicle when you press the brake pedal. Unlike other critical brake parts – such as the master brake cylinder, brake lines and calipers – your rotors and pads are subject to more “wear and tear” than other areas within the brake system.
To stop your axle from turning, the brake pads are compressed against the rotor (on both sides of the rotor for an even stopping motion). This metal-on-metal activity can cause both the rotor and pads to wear down. Thankfully, today’s brake pads offer much better performance and durability than yesteryear’s variety.
Brake pads are primarily constructed two different ways:
- Semi-metallic pads – this more common type of brake pad consists of metal shavings bonded together by a high-strength resin. Semi-metallic pads are the most affordable and widely-used type of brake pad.
- Ceramic pads – for better performance and longer wear, ceramic pads offer a lightweight design and superior characteristics when compared with semi-metallic pads. They’re made of ceramic fiber, filler agents, and a few metals that help lessen heat buildup during normal braking.
Which brake pads are the right ones for your car? As long as you’re using the OEM part number for your car’s brake pads, you can use different materials if you choose. For instance, if your car had factory-installed semi-metallic pads, but you choose to use ceramic pads, that’s fine. As long as the pads fit like they’re supposed to, material choices are secondary. Your own driving habits, your daily commute, weather preferences – all of these factors can help determine whether or not you’d like to use semi-metallic or ceramic pads.
When your brake pads need to be replaced, there are a few telltale signs to pay attention to. A high-pitched metallic squeal probably means your brake pad “wear bar” (a small piece of metal that surfaces whenever your brake pad material degrades to a certain level) is contacting the rotor. But it’s not all about sound; note your car’s stability when braking. A slight wobble could indicate uneven wear with your brake pads, which would account for the uneven braking motion.
Both semi-metallic and ceramic brake pads are available at BuyAutoParts.com. Depending on your specific requirements, you can choose which style best fits your car. For normal everyday driving, semi-metallic pads offer the best value, without sacrificing brake quality and dependability.
The brake rotor works in tandem with the pads, and is usually made of metal – steel, cast iron and aluminum are popular material choices – although the ceramic rotor is much more prevalent nowadays. To help release the terrific heat during the braking process, rotors are drilled, vented or slotted. This small but necessary design modification greatly reduces the chance that your rotor will “seize up” during braking.
A “warped” rotor is when the rotor surface has small bumps, pits and other defects that prevent the rotor’s surface from completely touching the pads on each side. Rust, excessive heat, worn pads and a host of other factors contribute to a warped rotor. Take note of minor changes when you brake – it could be the sign of a major issue you’ll have to deal with soon.
Up to the mid-1990s, it was common for cars (both domestic and foreign models) to have a different brake system for the front and rear wheels. Most automobiles in those days featured brake pads and rotors on the front axle, and something called drum brakes on the rear axle. Drum brakes worked by pushing the “brake shoes” inside the drum outward, thus generating enough force to help halt the rear wheels. But a few reasons have made drum brakes increasingly unpopular for new car designs. For one, they’re typically tougher to change than pads and rotors; the drum brake assembly has numerous springs and other small components, so it’s a bit more confusing than a traditional rotor & pads configuration.
Drum brakes have been phased out of most new cars in the American market, yet some remain. You should keep this mind if you have an older model, as the rear brake system might consist of a drum assembly.
Whatever brake system your car uses, BuyAutoParts.com has the right OEM replacement rotors and pads you need.
Calipers and Brake Cylinders – Two Behind-the-Scenes Essentials for Stopping Your Car
While your car’s brake rotors and pads are the most widely recognized elements of the braking system, you can’t forget about some other components that help your car slow down & stop.
In a conventional disc brake system (usually on your front axle, but also on your rear axle, especially for newer cars), a closed-pressure system of hydraulic brake fluid helps move the master cylinder, and this action pressurizes the brake calipers. This cylinder – caliber dynamic is what actually causes your brake pads to press up against the rotor.
The caliper is situated over the rotor like a clamp, which allows for control of the brake pads on both sides of the rotor. When the master cylinder is activated by the brake pedal, the brake fluid in turn causes the caliper piston to move, forcing the pads to “grab” the brake rotor.
One overlooked part of every brake caliper is the glide pin. Each brake caliper contains a pair of glide pins, which slide back and forth to help distribute even pressure from the caliper piston. When the glide pins become defective, one side of the rotor will receive more brake pad pressure than the opposite side, and brake efficiency will suffer. In areas with harsh climates (especially cold winter weather), excessive road slush, ice, salt and grime can compromise caliper function, especially as it relates to the glide pin. Looks can be deceiving; a seemingly well-working caliper could have defective glide pins inside, thus preventing solid, even pressure transfer from the pads to the rotor.
When ordering a master brake cylinder and calipers, you should have your automobile’s OEM part number for easy reference. With a wide variety of OEM-quality brake cylinders and calipers available at BuyAutoParts.com, you can order an exact replacement part, designed to perform just as well as the original factory-installed brake part.
Anti-Lock Braking Systems
To prevent your brakes from locking up from too much pressure exerted by the brake cylinder (and thus to the pads on the rotor), a safeguard exists. It’s called an ABS (anti-lock brake system). Situated between the master cylinder and the axles, the ABS keeps one wheel from receiving too much pressure. When your car’s ABS detects that one wheel is getting more pressure or turning at a slower rate than the other wheels, the ABS regulates brake fluid pressure to allow the wheel to turn momentarily. Essentially, the ABS is a pressure regulator for your entire brake system.
Before ABS systems became widely available, it was common for a car’s brake system to freeze up. Obviously, this had tremendous safety implications, so automobile manufacturers and engineers devised a simple yet effective mechanism to avoid the loss of brake power to any or all wheels.
BuyAutoParts.com has ABS modules to keep your car’s brake system safe, smooth and efficient. If your “ABS System Warning” light (or similar notification) is on, you should replace your ABS module as soon as possible.
Signs of Brake System Trouble
One bad brake part can have dire consequences for driving safety. You should be aware of certain signs & symptoms of brake system trouble. Some are obvious, while others are harder to detect. But attentive drivers can diagnose most brake problems with very little effort. If your car experiences any of the following, it is recommended to replace the necessary brake parts immediately.
- Soft brake power – the brake pedal presses to the floor with very little effort
- Scratching or squealing sounds
- Wobbly / uneven stopping
- Brake fluid dripping from bottom of car
- Grinding sound when braking
- Brake system or ABS system warning lights on control panel
- Low brake fluid level
- Obvious residue in brake fluid
- Burning smell or smoke when braking
The above conditions are just some of the warning signs of a faulty brake system. Once you’ve determined the exact cause of the problem, you should replace the defective brake parts at once.
