You have a master cylinder and splitter problem that is allowing too much pressure to the lines or you have the routed incorrectly and they are pinching. Since the latter is not very likely I recommend replacing the Master Cylinder and if that doesn't fix your problem then look at the splitter. (This assumes you have a separate splitter coming off the master cylinder where the 4 lines connect to that instead of the Master cylinder directly.)

.brakes line locateions 1996 gmc 1500

Have to fabricate new brake tubing & just replace the rusted
lines as you see them.

If you get under there & look, you will have your answer

A guess from my experience, would say you start at the proportioning valve & go past the door & leak, to the rear
somewhere at a junction block on the axle housing or to an
abs hcu unit, if one of them there along the way

Sometimes you need to make two lines with a union under the door,
as that is the longest run under a truck & to do one piece may not be
possible & get it in place, with all the bends & things you have to pass

On a 1996, I would suggest you bleed all four corners first
Then remove the master cylinder & clean out the moisture
Then replace All rubber flex hoses
Then replace the entire brake system lines
Once one rusts out, their all months apart & unsafe to use
piece mealing it one section at a time

Hi oakleafwoodw, sounds as if the brake master cylinder has busted a seal allowing the brake fluid to leak by cylinder when you push the brake pedal giving you no or very little pedal is located under the hood on the drivers side firewall, you will see all the brake lines attached to it , remove those and the two bolts holding it on,take it with you to auto parts store for a rebuilt one , they will keep your core for rebuilding, other wise you pay a core charge., verify that they have the one you need before hand, get a quart of dot 4 brake fluid, hook it up, and bleed air from the brake lines starting with wheel cylinders in this order Right rear......left rear.....right front.....left front...making sure to keep fluid level topped off in the master cylinder during the whole bleeding process or you will pump air into lines....OK!! caution: you should not drive it until you have good brakes!! you said they still work but if you had to stop suddenly ,it won't do it.

Loss of breaks. Brake fluid leaking from brake line near rear wheel where the line is strapped to the frame. Any ideas? Am I looking at a big repair bill?

No, happens all the time to rusty lines. Have it towed to a brake shop. Brake line replacement is relatively easy but requires a couple of special tools. If the line goes over the gas tank, I usually just leave the busted part up there and reroute a new splice to the wheel cylinder. Labor should be no more than a couple of hours if they do it that way.

Brake lines rusted under car for back brakes, is there 2 lines going to the rear. brake line busted

You do have 2 lines to the rear on the Lincoln. Both should be replaced if they are rusted out. After replacing the lines will need to be bled of all the air.

The right front caliaper is locking up both calipers are new and a new mastercylinder is new also whate do i look for a pluged line?

One of the most common causes of what your experiencing is from a collapsed flex line at caliper. The inside starts to deteriorate even though outside looks fine, and plugs line which will not allow fluid to return & release caliper. One way of checking is, jack that wheel up, apply brakes, then release & see if caliper still holding, if yes, try same but this time be ready to crack bleeder screw open. Crack bleeder, and if caliper releases, I'd change that hose. Keep me posted.

The brakes suddenly went out in my 1998 saturn wagon

Open up the hood and locate the brake fluid reservoir and see if there is fluid init if there is no fluid the brake line has busted somewere inbetween the master cylinder and one of the 4 brakes. to find were it is broken fill the resivore full of fluid and put the cap back on now have some one pump the brakes slowly and you should see a stream of fluid coming out some were. this is were your line is busted. if you located the brake you can go to an auto parts store and get a compression coupling to splice in a new part of the brake line.
hope this helps you out
please leave me a rating
Thank you
