New! This exclusive MM kit allows easy installation of an adjustable brake proportioning valve.

Installing an adjustable brake proportioning valve requires disabling the original factory proportioning valve, either by removing it from the system, or by dismantling it and installing a different end plug. While it is common for racecars to have the brake lines completely re-plumbed to eliminate the stock proportioning valve, MM designed this kit to allow easily removing the stock proportioning valve while also retaining all of the stock brake line plumbing. This is much easier to do than the alternatives of either dismantling the stock valve or re-plumbing the hard lines! Replacing the bulky stock proportioning valve with the much smaller MM Eliminator kit also cleans up the engine compartment, for improved appearance.

The MM Brake Proportioning Valve Eliminator Kit maintains separate front and rear brake hydraulic systems. It is only to be installed on Mustangs that also have an adjustable proportioning valve. This product is intended for off-highway application only.
