My car has Wilwood front disc brakes, master cylinder, adjustable proportioning valve, and residual pressure valve. I have the factory drums brakes, hence the residual pressure valve.


I've bought a new rear end that is coming with disc brakes, so is all I need to do is just remove the residual pressure valve and re-adjust the proportioning valve?


Is it that easy? I just want to make sure.


Thanks!

Yes just remove the valves

Are there not different MC's for drum/drum, disc/drum, and disc/disc?

Perhaps there is, but I have one that is agnostic:

I'm doing a 4 wheel conversion at this time. Wilwood sold me one of their master cylinders with the adjustable proportioning valve. They suggested the prop valve for additional bias adjustment (front/rear) but, their MC is for a disc/disc set up. I'm still not sure if the prop valve is really necessary.

When I put my Wilwoods on I used their adjustable proportioning valve and it was very much needed. My back brakes were locking up long before my fronts kicked in. A lot of hard braking test and adjustments later no matter how hard I hit the brakes now I stay perfectly straight. I'm not using wilwoods MC but I do have one made for four wheel disk.

So this is the link to the part that I'm removing:

Searching eBay there are a lot of different brake line couplers for 3/16th hard lines. I don't know jack about flare types, can someone please help me out with exactly what type of coupler I need to replace that pressure valve?

Thanks!

I bought this one, hopefully this does the trick:
