Thread: Brakes??

Tweet

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.

Don

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?

Are you upgrading to disc from drum?

If so don't forget the proportional valve...gave me some problems when I upgraded the old '48 chevy. Someone else may be able to offer a clearer explanation

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.

In my opinion, you definatly want to go with a dual master. Do any of the aftermarket companies make a 12 volt solution for the vaccume? not to sound dumb but there could be such a device, haven't looked

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.

I`m running drum /disc, non power Koulade, Its not a problem, my coupe weighs in at 2700 with my butt in it, keep the master cylinder bore to one inch, not more than that, that will keep your line pressure up.

Here`s a link that may help.

I am running disc/disc and I am not running a brake boost because i would have to buy an eletric one and those are around 300.

There are several cars and trucks that have diesel motors, they didn't use vacuum for their power brakes. Some used hydro-boost and some use electric-boost for their power brakes. The hydro-boost used the power steering pump to power them, and don't use any power till you step on the peddle, so it won't hurt HP motors, and the electric used 12v to run the pump.

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!

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.
