1999 Sable Brake line fluid leak

I have a 1999 Sable with brake line fluid leak in middle of chassis by driver door(underneath)  There is an unusual part joining front & back brake lines that is leaking on both ends.  It looks like rubber grommets are the joint to the brake lines.  It is hard to see because I am in Michigan and we have snow, salt, water, dirt, mud and it's hard to find time to crawl under rusty vehicle to look thoroughly at the leaking joint in 20F and 20MPH winds.  Brake light is on and pedal goes to floor.  I keep filling fluid but leak is out of hand.  Does anyone know what kind of part joins lines together in mid-chassis?  Why isn't line continuous to back? Why the break & add another part?  I thought I would ask before I 1) buy a service manual & figure it out myself.  2) Take it to dealer & pay $$$.  I am poor & trying to make ends meet.  Thank you for any help !!  If I have an answer, I can call friends that will work for beer.  Thanks - Superbuuck

    I found out the unusual part in mid-chassis was actually the CABLE emergency brake lines. It was a shock absorber grommet that joined two cables from front to back of vehicle. My leak was the actual hydraulic brake lines that were tucked up in the frame even higher in the darkness. I researched how to replace my hydraulic lines because they were very rusty in multiple locations. I ended up going to a Ford dealer and buying "pre-bent" lines and put them in. I had to learn how to bleed the air out of the lines but I was successful. Now I am smarter for it! Thanks,

    I've got a leak in the same place. What I'd like to know is how the lines run from the master cylinder. There's a line that enters in the front-top if the master cylinder, and one at the rear-left. I blocked the rear-left line, but it still leaked. I blocked the front-top line, and the leak stopped, but I only had rear brakes and no front brakes. Can someone explain to me how these brake lines work??

Cut that out. Replace it with a compression fitting. Bleed the system.

My front passenger brake is sticking on a 1999 mercury sable

replace the brake hose as they can collapse inside causing the fluid to be trapped and not allowing it to travel back to the master cylinder causing a line lock effect.

Underneath my tahoe on driver side is a small leak,clear fluid what can it be ?

Maybe brake fluid. Under the hood on the drivers side is the brake fluid reservoir and the brake lines generally run from there, under the drivers side, to the rear brakes. The lid may be loose or a line may be leaking. Would help to have someone look under the vehicle while someone pushes the brake to see if fluid is dripping.

1999 brakes pushed all the way to the floor don't work, and there is fluid leaking on drivers side rear

Sounds pretty cut and dry to me...You have a wheel cylinder, a caliper, or a brake line leaking. Find out which it is and fix it and your brakes will work again.

The brake fluide is leaking I have filled up 3 time in 7 day how can I fix it

Look where the fluid is coming from under the car if it is in front of the car it is a front brake line issue these are easy to fix. look at the brake hoses on the left front and right front behind the tire these usually these lines dryrot and leak. the front steel brack line will usaully brake where they are mounted on the car body. If your brake line is leaking from the drivers door back it is a rear brake there is a single brake line that goes to the back and splits into two lines there is another rubber hose by where they split. you can fix brake lines with new steel line and compression fittings where you slide on and tighten the front is 1/8 size line and the back brakes are 3/16.

We have a 1999 Sable and the brake lines are leaking badly. We have new brake line to replace the old but cannot get the nuts off where they join just in front of the rear drivers side tire. Is there a...

The nuts are maybe rusted and now no wrench will fit, you may need to replace it all. There is no easy way, they usually need to be made and flared on the spot and bent to fit.;
