right now i am running my brakes off a brake booster which always supplies 18 psi to the brakes at all times. They are not even hoooked up to the master clyinder i believe. The parking brake was also cut in the rear so i believe i have to re run some new lines so i can haev a parking brake. But how hard is it to replace the master cylinder because i believe the one on it now is shot. Also where can i find this system or what is the best and cheapest way to go. I would like to have 4 wheel disc brakes but i have front disc and rear drums. Thankyou

Hmm, I'm thinking your brakes wouldnt' work if they weren't connected to the mc. You can get a new booster/mc combo in the neighborhood of $140 approx. Parking brake cables are readily avail at any parts house.
