Brake Proportioning Valve Kit
The kit includes a pre-bent supply line, pre-bent output line, fastener pack, laser cut proportioning valve mount and the optional Wilwood proportioning valve.
The proportioning valve allows you to balance the front to rear brake bias to improve braking performance and decrease the chance of front wheel lock-up. The improvement is more noticeable on Goblins running the DF Kit Car parking brake setup.
To select the correct proportioning valve kit, compare the sizes of the two fittings of your master cylinder. If one is smaller than the other, you should select the M10 option. If the two fittings are the same size, select the M12 option. Most non-TC cars will use the M10 fitting but some 2.4 liter cars have the M12 fitting. All TC cars use the M12 fitting.
