ONLY ORDER IF YOU ARE CERTAIN THIS IS FOR YOUR MASTER CYLINDER. IF NOT SEND A PICTURE OF YOUR MASTER CYLINDER FOR US TO CLARIFY.

Having your thumb brake or finger brake installed in conjunction with your rear master cylinder has never been easier!⁠

Our Junction valves are dual-fitting kits.

Junction valves go into the rear (foot) master cylinder and allow both Thumb brakes & scooter brakes to work in conjunction with the footbrake master cylinder.

⁠
RTX477 is our new Titanium (Nitride coated) long neck type which fits in Nissin and aftermarket type master cylinders with a plastic nipple and circlip, ID = 18.5mm (Due to the size of the long neck type you require x4 standard copper washers or x2 2mm copper washers)

The Plastic nipple type master cylinders are fitted with an oring and circlip.

Please contact us if you are unsure, See list below to what fits what so far.

A DOUBLE BANJO ON THE REAR (FOOT) MASTER IS NOT THE SOLUTION AND WILL NOT WORK THIS IS WHY JUNCTION VALVES ARE REQUIRED.
