Sounds like the original e-brake will totally work for my set-up.

Follow up question: If I stick with the front and rear disc setup, can I still use the stock hardlines? I am assuming I will need a proportioning valve specifically for disc/disc setups. Can anyone point me to a good option for a proportioning valve? Or a thread that covers this for disc/disc setups?

Any advice is appreciated! I know next to nothing and I am rapidly trying to educate myself, so I appreciate any advice or information!
