Just work as though it wasnt their and stop getting technical and worring about things that dont concern you with changing the master cylinder as this is the cause of the soft pedal ,the internal seal between fron and rear chambers has failed causing the soft pedal now no excuses get out and do it and stop looking for any excuse not to do the job it will not get done by talking about it

You still have air in the system. You will have to bleed more. I had to bleed a quart of brake fluid out of each wheel to get good brakes on my 1996 GMC.

Brake proportioning valve

It could be your break line is clogged with air bubbles or your brake pads/shoes are contaminated. If not that I'd say you need to replace your master cylinder. You can buy a used master cylinder online for pretty cheap.

Not getting break fluid to the back lines

Hmm, well you're not telling us much like the make model year? Anyway to take a stab at it you may have a bad master brake cylinder or even a bad proportioning valve. Check to see if you have pressure at the proportioning valve. If so then the master cylinder is fine and your proportioning valve needs to be replaced. But if there isn't any pressure there then of course it's your master cylinder. But again since I don't know anything about your vehicle I'm assuming it's an older one with a standard type of braking system. As you get newer then you get into much more things that could go wrong.

95 Buick LeSabre, brakes will only hold for a week then have to re bleed the system.has new master cylinder,Any ideas

Check all your brake lines especially those going to the bleeder valve where you find the most air when bleeding. Also check for leaks at the rear of the master cylinder and at the calipers and wheel cylinders. If either half of the master cylinder is going low, that shows you there is a leak somewhere. If it's staying full, I'd suspect the master as having an internal bypassing problem.

Air in brakes. tried to bleed them and they still go all the way to the floor. what do i do?

Make sure you have all leaks are fixed and the brake fluid full. If so find your proportioning valve normally under the master cylinder where you fill the brake fluid. Tap on the valve with small hammer while someone is pumping the brake pedel fast and hard. Then try bleeding the brakes again.

I need a break line diagram for 1995 ford countur

It doesn't connect to master cylinder. The line should connect to a proportioning valve, then from valve to master cylinder.Star at master cylinder and follow lines to proportioning valve.

Brake pedal goes squishy and fluid in the front of the engine on top..not back by the master cylinder

If you look down under the radiator in the area of the power steering pump, nestled in the crossmember you should see some brake lines going in and out of a rectangular steel block. It should also have a single wire going in the top. That is the proportioning valve which adjusts brake pressure to the wheels. One of these lines is likely the source of your leak. Hope this helps.
