NISSIN Twin Port Rear Master Cylinder – 1/2″
A genuine NISSIN rear master cylinder with two outlet ports, built for riders who want a foot brake on their electric dirt bike without giving up the rear hand lever.
Two ways to run it
- Independent caliper: drive a second rear caliper (e.g. a dual-caliper rear setup) from the foot pedal alone.
- Shared caliper: link it with the rear handlebar master cylinder through a purpose-designed valve, so foot pedal and hand lever both operate the same single caliper.
