Larger rotors can be used to increase braking force, but this also increases weight and inertia. To overcome this brake manufacturers developed calipers four, six and even eight pistons. [14] Increasing the number of pistons increases the swept piston area, allowing for longer, narrower brake pads and smaller discs.
A combined braking system (CBS), also called linked braking system (LBS), is a system for linking front and rear brakes on a motorcycle or scooter. [1] In this system, the rider's action of depressing one of the brake levers applies both front and rear brakes. The amount of each brake applied may be determined by a proportional control valve ...
The front brake caliper is mounted on a hinge, and uses the torque created in the braking action to operate a valve in the fork, which inhibits the flow of oil during braking. This system was fitted to a number of motorcycles, most notably the Goldwing series from 1983 through 2000, the Pacific Coast , CB1100F , CB1000C , and VFR750F .
A motorcycle fork is the portion of a motorcycle that holds the front wheel and allows one to steer. For handling, the front fork is the most critical part of a motorcycle. The combination of rake and trail determines how stable the motorcycle is. The 'fork' on a motorcycle consists of multiple components.
A drift-inducing technique called "the brake drift" is used in racing, involving a series of light rear brake trail-braking pulses (usually 2 or 3), followed by a momentary full-force rear braking and sharp releasing of the rear brakes. Mastering continuous trail braking as used under road conditions is a prerequisite for learning brake drifting.
When braking, the rider in motion is seeking to change the speed of the combined mass m of rider plus bike. This is a negative acceleration a in the line of travel. F=ma, the acceleration a causes an inertial forward force F on mass m. The braking a is from an initial speed u to a final speed v, over a length of time t.
The brake lining is that part of the brake pad which actually contacts the metal brake disc (rotor) when the brake is engaged. Using a typical bicycle brake as an example, the backing would be the metal shell which provides mechanical support, and the lining would be the rubbery portion which contacts the rims when the brakes are applied.
The use of the drum and flywheel meant the valve only opened when the wheel was turning. In testing, a 30% improvement in braking performance was noted, because the pilots immediately applied full brakes instead of slowly increasing pressure in order to find the skid point. An additional benefit was the elimination of burned or burst tires. [6]
