Coaster brakes

Instead of operating by hand, coaster brakes are actuated with the legs by pedaling the crankarms backwards. The chain transmits the motion of the crankarms to the rear hub. The braking mechanism is actually inside the rear hub. This system consists of several parts:

• Rear hub (with brake strap and brake arm)

• Chain and crankset

Inspection

Once a month check that the brake arm attachment bolt is tight and that the brake strap is securely fastened to the chainstay (Figure 1 and Figure 2).

Once a month, or whenever the wheel is installed, check the chain tension. Without proper tension, the chain can come off, and the brake will not work. Also check the adjustment of the chain tension.

Warning—If the chain comes off, the brakes will not work. Without brakes, you could lose control and fall. Before every ride make sure the chain tension is correct, and that the rear wheel is securely fastened.

Adjustment

Coaster brakes are not adjustable. If the brake is not functioning properly, take the bicycle to your dealer for service.

See Drivetrain for Inspection and Adjustment of chain tension.

Lubrication

A coaster brake is inside the hub, and does not require additional lubrication. Follow the recommendations in the Wheels section for lubricating hub bearings.
