Gen2/Rear Brake Actuator

The rear brake is manipulated by a dirt-bike style pedal around the right footpeg, a common motorcycle configuration.

S and DS foot pedals compared

The rear brake has its own master cylinder behind the rear footpeg on the right.

Pedal Construction

Cast aluminum with a powder coat finish.

On pre-2015 models, the pedal is made from a single piece.

On 2015+ models, the pedal toe actuator is bolted on (M6X20-8.8) and may be replaced or have an S vs DS toe actuator swap.

Rear Brake Switch

The rear brake switch is activated hydraulically by pressure in the rear brake system.

The rear brake switch is built into top banjo bolt.

Rear Brake Pedal

The threaded rod from the brake lever to the master cylinder adjusts lever height.

Rear Brake Pedal Adjustment

The rear brake pedal is adjustable at the clevis.

1. Remove the pin.

   The pin is the part that connects the brake pedal to the clevis.

   The clevis is the fork shaped part that goes either side of the sheet metal pedal.

2. Loosen the actuator shaft locknut above the clevis.
3. Grip the shaft firmly with (say) long heavy-duty needle-nose pliers.
4. Rotate the shaft clockwise (back toward the rear of the bike) to lower the pedal foot.

   Or counterclockwise (towards the front) to raise the pedal foot up.

5. Tighten the locknut back up to hold the clevis in place.
6. Put the pin back in.

Rear Brake Pedal Spring

On most models, there is a spring suitable for a dirt bike that is over-designed for a street bike.

There is a kind of spring inside the brake pump, so the external one is just to keep the foot-pedal without rattling.

Suggestion: Remove the rear brake spring or replace it with a lighter spring.

Test the rear brake after doing this.
