My car is disc/ drum and I converting the rear to disc. Can I use the existing prop valve or remove it and install an adjustable one? Thanks

You do not need a prop. valve with disc brakes in all four corners, all you need is a distribution block.

What you don't need is a disc/drum combination valve, which is what you have right now.

You may, or may not need a proportioning valve depending on how well you did your homework. If you choose the wrong sized rear caliper you may need a proportioning valve to dial out any rear wheel lockup.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

You left out too much information so the only answer that fits is "it depends".
