Brake Pressure Sensor Adapter
Allows you to run a brake pressure sensor on you NB 99-05 Miata. Replace one of the short factory lines from the Master to the proportioning valve with our adapter and install your sensor. Especially valuable on the 2001-2005 Miata that does not have a banjo style fitting on the brake lines. Could also be used to measure front/rear brake bias. M10 x 1 fittings on either end with an 1/8 NPT port for your sensor. Professionally made with quality lines designed for high pressure. No need to drill and tap into your master cylinder.
