In the old days, brakes were not a part of the vehicle to be shown off as something decorative, such as chromed engine parts or anodized wheels. The brakes, which convert the kinetic energy of the moving vehicle into heat energy through friction, were once just dirty and often rusty cast-iron parts hidden inside the wheel, quietly (or sometimes not) performing their duty.
With modern performance cars offering more power and speed, as well as higher curb weights, the size and capacity of the brakes have also increased to produce the kind of stopping power that is needed in today’s cars. Since the late 1980s, when lighter alloy wheels began to open up increasingly larger windows into the brake’s hot, dusty, and dark world, brake calipers on sport cars began to be painted in bright colors, and brake rotors became vented and cross-drilled for better heat dissipation. They became something to look at; indeed, something cool to differentiate vehicles and draw people’s attention. Car dealers started to offer special colors for brake calipers, and today the option can sometime cost thousands of dollars on some supercars. Car designers nowadays also design wheels with thin and widely spaced spokes, both to shave weight and also to show off the colorful brake calipers and large rotors. The caliper face has since become a promotional space for brands and logos because people can now see it.
Large aluminum calipers with six or more pots that are mated with expansive cross-drilled rotors are expensive car parts. They are primarily fitted on supercars such as those from Ferrari, Lamborghini, and Porsche, though people often spend thousands of dollars to retrofit big-brake kits to lesser cars.
AUTOart has now launched a new six-pot brake disc keychain for people who are serious about their brakes and their car passion. They can carry it around in their pocket and show off their automotive passion wherever they go, no attached supercar needed. The keychain features a rotor that actually rotates within the brake caliper, which is sturdy die-cast zinc metal cast to an authentic shape to resemble the massive six-pot calipers fitted to the world’s elite automobiles. A replica of the external brake line is fitted at one end of the caliper, just as they are on the real items.
As with a real brake rotor, the 31mm (1.2-inch) diameter chrome-plated die-cast zinc rotor is a double-disc bridged by ventilation slots along the edge. The rotor surface is fitted with a photo-etched and stainless plate that has been manually brushed to simulate the hairline braking marks left by the pads.
The center hat of a two-piece assembled rotor, which is the most expensive component of the whole product, is machined from billet aluminum by AUTOart and then drilled with twelve little holes around the outer rim to fit with the replicated “bobbins,” which on a real two-piece brake are a specially designed bolt to mount the rotor onto the aluminum hat.
The stainless steel keyring is strapped to our mini brake by stitched vinyl for years of rugged use. The total length, including the keyring, is 90mm (or 3.55 inches). It is carefully packed at AUTOart’s workshop in a gift box with a clear window.
The three colors of caliper available are: red, yellow, and black.
