s of disc brakes, first using the Jaguar brake caliper on its LeMans entries back in the 1950s. The design was successful, and the Jaguar brake caliper has been used ever since. While the details have evolved over the years, the basic operation of the Jaguar brake caliper and the Jag disc brake system has remained remarkably similar. Essentially a lump of steel with one or more pistons riding in a machined bore, the Jaguar brake caliper receives brake fluid under pressure from the master cylinder when you apply the brakes. That brake fluid forces the aforementioned pistons, and the brake pads connected to them, toward the center of the Jaguar brake caliper. When the Jaguar brake caliper is bolted to your E-Type or X-Type, it straddles the brake rotor; the brake pads 'pinch' the rotor when fluid pressure is applied creating friction and stopping the car. Simple, right? Okay, so the Jaguar brake caliper isn't easy to describe, but with a good Jaguar repair manual in hand you should be able to figure out the operation of your Jaguar brake caliper in just a few minutes. But why on earth would you be down in your wheel wells checking your Jaguar brake caliper in the first place? Fluid leakage is the main thing that might inspire a Jaguar brake caliper inspection: If the master cylinder is consistently low, a leaky Jaguar brake caliper may be the reason. If the brakes are pulling or making unusual noises a thorough inspection of all the brake parts, including the Jaguar brake caliper, is in order. But whatever the cause may be, you can order a new Jaguar brake caliper from us for less than the specialty parts houses or dealerships will charge. You get the same OE quality Jaguar brake caliper, you just pay less, so you can get your broken Kitty back on the road in a hurry.
