I need to do all my brake lines and I need a new manual dual master cylinder. It will be on the original flathead engine with disc brakes in the front and rear. The rear is out of an explorer 8.8 with the original brake lines still on it. What size brake lines and what all do i need to get to complete this project?
3/16. You will need some step up adapters at the hoses and other places but these are common auto parts items.

and don't forget that the rear will probibly/might be a metric thread. my m/c and prop valve and rears are metric and the front is Sae. then I couldn't find a metric tee for the rear line so that is sae. You also might have to do bubble as well as double flares. good luck
Is there manual dual master cylinder that bolts on to the original brake pedal?Quote:

If so don't forget the proportional valve...gave me some problems when I upgraded the old '48 chevy.:o Someone else may be able to offer a clearer explanation:D
Good luck!
I am upgrading from all drum to all disc. I have the original flathead that doesnt have enough vacum for a boost brake. It has to be a manuala dual master cylinder i guess, or back to the orginal single master cylinder.Quote:

I have seen them on other websites. Try Poise's on line catalog page 48. They are around $300. I just googled them and a few came up.Quote:

Here`s a link that may help.

Search and find out which cars & trucks used which, and use that power setup for non-vacuum cars!
I always hear people saying they can't run power brakes with their turbo's and blowers because of no vacuum. When they can, and have strong brakes, with little foot power! :HMMM:
People don't search for parts that were used anymore, they just look in catalogs and point!
Heres a picture of a hydro-boost someone used on theirs.
