Proportionately awesome

Summit RacingSummit Racing Verified Purchase

Replaced my single pot brakes in my 66 Coronet with a dual pot and put this in line with the back ones. Have not cone much tinkering with the settings but I can tell it is doing it's job. Good price and easy to install (except for having to bleed the brakes... what is is about bleeding the brakes? Its probably my least favorite thing to do on my car). ...read more

I used this unit to replace a factory GM proportioning valve. It worked best at the lowest setting so a little more adjustment on the low end could be useful.

absolutely necessary

Summit RacingSummit Racing Verified Purchase

Same design as the first ones from back in the 80's. The same quality, comes with adapters for 3/16 lines. I have used a dozen of these with absolutely no returns. They are easy to adjust and mount friendly.

did not work

Summit RacingSummit Racing Verified Purchase

installed on rear brakes to achieve a more balanced effect. After installation and bleeding tried to dial it in when noticed no change by feel. Decided to use my fluid gauges and to my surprise no matter if was turned down or all the way open pressure was the same. Going to have to build something else. Master Mechanic Joe Holihan
