Racetorx Brake Junction Valves

Racetorx Junction Valves

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.

⁠
So far we offer 5 types:

RTX450: which is used in the likes of Brembo Master cylinder Part number – 10850560

RTX452: is a Teardrop shape with a M4 bolt this is used in Brembo, Nissin and aftermarket master cylinders

RTX477: is our new Titanium 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)

RTX479: is our new Titanium long neck type, this is suited for some Brembo & aftermarket type master cylinders with a plastic nipple that can spin, ID 14mm. (first of its kind) for OEM Brembo masters like on the KTM Superdukes etc) (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 pushed in with a rubber doughnut, you can pry these out with a set of players to fit the Longneck junction valves

Please contact us if you are unsure, See the list below for 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.
