I have the floor mount master with booster. I the 2 lb. resadual in the lines. I was talking to classic hauler 2day and Candie said the power boosters don't need the resaduals. So before i take them out i wanted to run this by you guys. I blead the lines and the master 2day and they are better. The pedal will come back up on Its own BUT still ain't got the brakes i should have.
Who's master cylinder booster do you have? CPP's come with a proprotioning valve but it still needs residuals. 2lb for disc, 10lb for rear.
Did you bench bleed the new master cylinder first? You must.

I have rear disk . Do i need 10 lb. for this ? Can the master be blead on the truck ? I blead it 2day by useing the plugs on the side were there are no lines hooked to it.

2 pound residual valves for discs, 10 pound for drums, front or rear makes no difference. I have seen in the C/H catalog that the external residual valves are not necessary with their kit. They are supposedly built into the m/c already, so you don't need two of them. And if they told you that on the phone, I'd go with it.
The benefit to bench bleeding on the bench vs. in the car is you can get a better feel for whether or not the plunger is getting a full stroke all the way in the m/c. That's important. You can do the plug method like you did, but I like to make short lines that loop into the reservoir, so you can see the bubbles come out from the system as intended, while pushing the plunger in slowly. I think it's better, fwiw.
Disc brakes require a 2 lbs. residual valve and drum brakes require a 10 lbs. residual valve. You can have more then 1 residual valve on the same line and it will not effect it negatively. Some master cylinders come with built in residual valves. You'd have to check with the manufacturer of your master cylinder. Here's a good little read...

Thanks wayne and chris. I was looking it the configuration on this link and it has the back port on the m/c going to the front and the front port going to the back. YALL think this could be the trouble ? Thinking mine are front port to front brakes back port to back brakes. I can't remember But do the residual have a inlet and outlet marked ? I bought this unit from fatrodder on ebay I THINK. I really don't know what brand it is. This brake thing is about to get to me.
Front to back and back to front would only matter if the residual valves are built in, and they are set up for a disc/drum combo. As long as the right valve is going to the right set of wheels it shouldn't matter. If you had to tell him that you were running a disc/disc, disc/drum or drum/drum setup it probably has valves built into it. I'm not sure how to double check that though. I'm sure someone smarter then me can help you with that...
If you have 4 wheel discs with a 4 wheel disc master cylinder, it shouldn't matter which port goes where. Residual valves do have a dedicated in and out. If they're in backwards, it'll really mess you up. Personally, I would take those clear out of the system and see what happens.
I beat you this time, but I forgot about the directional valves... Like Wayne said, all residual valves I have seen have directional arrows on them. If they are backwards you are causing a restriction in flow the wrong direction...
I have the 4 wheel disk setup. Monday i will do like Wayne said and run a short line into a bottle so i can see the bubbles. I really need to get some good brakes so i can go to panama city beach for spring break and take some pics. for you guys. YOU GOING TO LUV THEM !!!! Can you say HALF NAKED DRUNK CHICKS ? Florida GOT TO LUV IT !!!!

You don't have to use a bottle. I just get a couple pieces of short brake line from the parts store, 8 or 9 inches or so, (they're really cheap) connect one end to the m/c fitting and loop the other right back into the m/c reservoirs. Work the plunger back and forth slowly until the bubbles stop, and you're good to go.
Oh, and I'd settle for half drunk naked chicks, too!
