Type of Brakes for a Recumbent Bicycle
-
Linear Pull
-
The linear pull brake, also sometimes called a "V brake," is the most widely used design of bicycle brake. The brake includes a pair of "arms," one on either side of the wheel, that are pulled simultaneously by a cable connected to a hand lever. The brake disassembles by simply releasing the cable from the brake, making the linear pull more accessible for purposes of cleaning. The pads and brake cable need to be replaced periodically.
Cantilever
-
Once common on mountain bikes, the cantilever brake has largely been replaced by the linear pull brake. Like the linear pull brake, the cantilever brake is particularly effective off road due to the relative ease with which it can be cleaned. The brake has two "arms" joined by a transverse cable, which pulls the brake at its center. Compared to more popular braking systems, cantilever brakes are more difficult to adjust. Brake pads must be manually "toed-in," a process by which pads are set at a particular angle from the braking surface of the rim. The process requires trial and error before success is achieved. Cantilever brakes, however, tend to be less expensive than other systems.
Dual Pivot
-
The dual pivot brake is the preferred braking system for road bikes. As its name implies, the brake pivots at two points. The dual pivot action allows the brake to stay centered above the wheel, reducing the need for adjustment. Like linear pull and cantilever brakes, the dual pivot brake pads and cable need to be replaced periodically. Unlike cantilever and linear pull brakes, dual pivot brakes are not designed for the rigors of off-road use. Small recesses on the body of the brake it make more difficult to clean than cantilever and linear pull brakes.
Disc
-
The most recent design of bicycle brake, disc brakes are also the most precise and powerful. Unlike other popular braking systems, the disc brake does not grip the rim of the wheel during braking. Instead it seizes upon a rotor attached to the side of the wheel. The use of a rotor reduces wear on the rim and allows the brake to be effective even if the wheel is slightly out of true. The brake is less likely to become clogged with dirt and mud, making it effective even in wet and muddy conditions. Compared with other braking systems, however, disc brakes can be more challenging to maintain for the novice mechanic. A series of adjustments and procedures is required for the brake to work effectively.
