Ensuring your ABS sensors are in working order is essential – not just for an MOT, but for your overall safety too. Our selection of ABS sensors has been chosen with quality and value in mind. ABS sensors are incredibly sensitive, individually monitoring the acceleration and deceleration of each wheel through an electromagnetic field generated by the wheel’s rotation.
Brake pads are a vital part of your car’s braking system, clamping down on your brake discs to bring your vehicle to a safe stop. If your brake pads are wearing out, pick up some new ones at our CMG Eurospares. Brake pads are flat components made of ceramic, organic or semi-metallic materials attached to a metal backing. Every time you apply the brakes, these pads hydraulically squeeze your brake discs, using pressure and friction to slow the movement of your car. Brake pads absorb some of the biggest forces involved in driving your car safely from day to day. While they’re made to last for many thousands of miles, they will eventually stop working as the abrasive surface is worn away. Fortunately, most brake pads will tell you when they’re getting old before you’re in any danger. If you hear a clicking or screeching sound when you apply the brakes, or if the brake pedal vibrates under your foot, it normally means you need to get your brake pads replaced.
The brake pad sensor is a single-use, but nevertheless essential piece of equipment. It performs the job of alerting you when your brake pads are wearing thin, which in turn triggers a warning light to indicate that it’s time to replace the brakes. In constant use or when placed under high levels of friction, a car's brake pad will inevitably wear down. When the pad has worn to a pre-programmed point, the brake pad sensor makes contact with the metal of the brake disc and completes an electrical circuit; this action sends a signal to the dashboard in the form of a warning light. Once a brake pad sensor has completed a circuit through contact with the rotor, it cannot be reused. Every time you change your brake pads you also need to install a new brake pad sensor. It’s recommended that you replace the brake pad sensor even if it has not made contact. The brake pad sensor is a real advance in automotive safety and your car will not pass its MOT if it has a faulty sensor.
For your safety and that of other road users, you must replace your handbrake drum as soon as it starts to show signs of wear. To find a new handbrake drum, look no further than the range of quality parts here at cmgeurospares.com. The drum is fundamental to your handbrake system. In fact, all parts in the handbrake system work together to help you control the drum and to keep it in place when required. The handbrake drum is a metal cylinder which connects to the handbrake lever via a series of cables. When you pull up the handbrake lever, the cables push brake shoes inside the drum to create resistance, thus stopping the rear wheels from moving. If disc brakes are installed on the rear wheels, then your parking brake uses its own drum. In this case, the drum will be built into your disc brake system. If your brake drum needs replacing, it may display a couple of symptoms. If your car still rolls when you engage your handbrake, or there is too much play in the brake lever, these are key signs that you need a new drum. While it is true that a defective handbrake drum won’t keep you from driving your car, it is in the interests of safety that you replace it immediately.
A worn or damaged brake shoe is a safety risk to yourself and other road users, and should be replaced every 50,000 miles. We stock high-quality brakes shoes for all makes and models of car. The job of the brake shoe is to produce the friction needed to slow and stop the car. It consists of a curved surface of steel covered on one side with an abrasive lining material. Brake shoes are to drum brakes what brake pads are to disc brakes. Disc brake systems can cope with higher temperatures than drum brake systems, but brake shoes are cheaper than brake pads. While brake pads can be bought with a choice of friction materials to suit different driving habits, brake shoes use a generic material and will perish more quickly if you are prone to excessive or hard braking. It’s advisable to replace your brake shoes in sets to ensure even wear.
ABS controllers are the components that instruct the hydraulic units to stop wheel-spin in a vehicle's ABS system. You can ensure that you order the correct controllers by entering your vehicle’s registration details above. The ABS system in your car is operated by a specifically designed computer unit and by braking sensors that are triggered every time the brakes are applied. The computer unit is referred to as the ABS controller. In a split second, this controller detects the presence of wheel-spin from the sensors and automatically instructs the hydraulic system to stop it. This technology isn’t 100 per cent reliable, so the computer can fail from time to time. If your wheels are spinning more than they should be, it could be a sign that your ABS controller needs replacing.
A worn-out or malfunctioning brake caliper can present a serious safety hazard. If you need a replacement, come to CMG Eurospares – we’ll get you back on the road at an affordable price. A brake caliper is a simple yet very important component of your disc braking system. Essentially, it’s the part that squeezes your brake pads against the surface of the rotor, creating friction that slows your car down. Your brakes may use floating calipers that move with the wheels, or fixed calipers that stay where they are. In either case, worn-out calipers can be a real danger to your ability to stop safely. Fortunately, they’re usually very sturdy and in most cases only need to be replaced every seven to ten years. However, heavy braking and minor accidents may put additional wear and tear on your calipers, meaning they need to be replaced sooner.
Given that the master cylinder will wear through normal use and can become corroded over time, it’s essential to replace it in order to avoid the risk of brake failure. A vital part of your car’s braking system, the master cylinder converts the pressure created by your foot pressing down on the brake pedal into hydraulic pressure, which builds up as brake fluid becomes trapped. This hydraulic pressure sets the whole braking mechanism into action, ending with the wheel cylinders demobilising the wheels. The master cylinder is a complicated piece of machinery, itself having a number of components. These include the housing, bore, brake fluid reservoir, fluid level sensor, piston(s), rubber cap, return spring and, in a manual car, rubber boot. Hydraulic pressure is instigated when the spring, cup and pistons slide in the cylinder bore. As an extra safety measure, modern vehicles usually have dual master cylinders, each with a different system of brake-circuit operation. If one cylinder fails (perhaps through the loss of brake fluid), the other will be able to work alone until the malfunctioning cylinder can be replaced. A common cause of failure is contamination or loss of brake fluid; if brake fluid becomes hygroscopic (attracting water), it will affect the system.
Brake discs attached to your car’s wheels work in combination with the brake pads to slow down your car by applying friction. Faulty brake discs can pose a serious risk to you and other road users. Brake discs are an essential part of a disc braking system. They consist of metal rotors attached to your wheels that provide a surface for brake pads to squeeze onto. When this friction is applied, it helps to slow your car down quickly and safely. As they’re such an important part of your car’s braking system, brake discs are heavy-duty pieces of kit that should last for years given the proper care, and your brake pads should wear out well before the discs. However, corrosion can take its toll over time, and brake discs can become dented and warped. If your car shudders when you apply the brakes, it’s often a sign that you need to get your brake discs replaced.
The handbrake cables link the handbrake lever to the parking brakes to stop the car from rolling downhill. Frayed or broken handbrake cables are dangerous and must be replaced. Different models of car use different handbrake systems, but by far the most common is a mechanical system of lever, rods and cables operated manually by the driver. A number of possible cable configurations can be used depending on what type of car you have (e.g. front- or rear-wheel drive), but a typical set-up consists of a primary cable attached to a yoke, and a secondary cable that wraps around this yolk and runs to each rear wheel. Pulling on the handbrake causes the primary cable to draw up the yolk, causing tension in the secondary cable; this instigates the braking action. If you find you are having to pull your handbrake very hard to keep your car stable on a hill, chances are your handbrake linkage system has worn over time and the cables themselves have slackened. Eventually the linkage will need replacing or else the cables might one day suddenly snap – rendering your handbrake both useless and illegal.
