Brake discs work similarly to bicycle brakes; when you put pressure on the brake pedal, it forces liquid through tubes and pistons, which causes the brake pads to squeeze onto the brake discs. This causes friction that makes the car slow down and stop. The brake caliper is the assembly that houses the brake pads and pistons. The pistons are usually made of plastic, aluminium or chrome-plated steel. Motorcycle Mechanics, April 1969, UK Lambretta Concessionaires advert, p.19. "...Lambretta have been fitting disc brakes...". Accessed and added 2015-02-20 Disc brakes are not self-energizing thus need higher clamping forces, which requires a power booster.

If there’s little to no resistance, you could have a dangerous leak, which you’ll need to call out breakdown assistance for. To help you out, here are a few noticeable things that can warn you of thin brake pads: 1. You Hear Noises When Braking

Light corrosion can come off with heavy braking, but if not, the corrosion gets worse and can lead to surface pitting. How often do you use your car?This one is easy to figure out - if you are driving more your pads and discs will be used more, and you'll need to replace them faster. Safety first – your brake system is critical to your safety and the safety of your passengers and other road users. Never take a chance with your brakes. You don’t want them to let you down when you need them most. The Jaguar C-Type racing car won the 1953 24 Hours of Le Mans, the only vehicle in the race to use disc brakes, developed in the UK by Dunlop, and the first car at Le Mans ever to average over 100mph. [15] "Rivals' large drum brakes could match discs' ultimate stopping, but not their formidable staying power." [4] Disc brakes are generally used in passenger cars, but due to their stable performance at higher speeds and resistance to brake fade, they are gradually spreading into the commercial vehicle segment, where drum brakes were traditionally chosen for their longer service life.

Inoue, H. (1986), Analysis of brake judder caused by thermal deformation of brake discs, SAE Technical Paper Series, no. 865131. Castings are subject to stringent safety tests and controls before being released for machining. These close tolerances provide hassle-free fitting for you, and comfortable performance for your customer.

Another advantage of disc brakes is their resistance to water fade, which occurs when the water on the brakes significantly reduces braking force. When the vehicle is in motion, the rotor spins at high speeds and this rotational motion discharges the water from the rotors themselves, resulting in stable braking force.

Although it fluctuates based on the type of road you’re on: the more miles you put in, the more you use your brakes and the faster your brake pads wear out. It's as simple as that. Brake failure can result from the failure of the piston to retract, which is usually a consequence of not operating the vehicle during prolonged storage outdoors in adverse conditions. On high-mileage vehicles, the piston seals may leak, which must be promptly corrected.

Unlike tyres, you can’t ‘see’ your brake pads and as they tend to wear over time it’s easy to miss the tell-tale signs. Wear and tear on your brake discs can reduce their ability to slow the vehicle down and cause vibrations through the brake pedal. If this is allowed to worsen, the pedal will stop interacting with the brake disc and prevent the car from stopping altogether. Obviously, this can be very dangerous; even if the brake discs aren’t worn to a severe level, your stopping distance can be vital if you need to make an emergency stop. In 1921, the Douglas motorcycle company introduced a form of disc brake on the front wheel of their overhead-valve sports models. Patented by the British Motorcycle & Cycle-Car Research Association, Douglas described the device as a "novel wedge brake" working on a "beveled hub flange", the brake was operated by a Bowden cable. Front and rear brakes of this type were fitted to the machine on which Tom Sheard rode to victory in the 1923 Senior TT. [6] Larger, more powerful car owners may want to fit metallic pads for their improved stopping power but should be aware that they’re usually louder than other materials. Vented disc brakes have a set of vanes, between the two sides of the disc, that pump air through the disc to provide cooling. Advantages Of Disc Brakes
