Learn more about how adjustable proportioning valves work by reading our tech article. Brake System Selection.  

Note: This is a universal fit and that due to the differences in master cylinder castings, that it's possible the bottom of the master cylinder OR the bracket may require grinding/adjusting to fit the bracket correctly. The lines may need to be "tweaked" to fit correctly and due to the different fittings on master cylinders, adapter fittings may be required as well.

Some parts are not legal for use in California or other states with similar laws/regulations
