Beringer Aerotec Hydraulic Thumb Brake Master Cylinder

Beringer Thumb Brake with 14.5, 17.5, or 20.5mm  pistons are ideal to control the rear brake on any 1, 2, or 4 piston caliper application. Can be plumbed directly to the rear caliper and will require a dual banjo bolt on the caliper.

It can also control a single 1, 2, or 4 piston front brake caliper.

When the rear brake pedal is still required, the Beringer Thumb Brake will need to be paired up with Beringer's MC127 floating rear master cylinder which has special piston cups allowing it to receive hydraulic pressure from the Thumbrake and to send hydraulic pressure to the rear caliper as well.

Dual calipers applications such as for stunt bikes require a larger bore size. Please Inquire.
