Question:
I had to replace the left rear bakeline in my 93 Corsica and I am having problems w/ bleeding them. I have tried to bleed them all day and I am still getting air bubbles. I did see a drop of brake fluid by the Master Cylinder, So I am wondering if the Master Cylinder is the problem.

if you wasn't having problems with the master cylinder before...it is most likely not your master cylinder is bad. However...if you let the master cylinder go dry...then you may need to bleed it before you bleed the rest of the system.Can cars run on veggetable oil?
To do this...simply have someone press on the brake pedal then crack the line coming out of the master cylinder. once it goes to the floor tighten the line and repeat this sequence until you get stratight fluid fromt the lines on the master cylender. You can do both lines at the same time to speed things up, once you get clear fluid there...you should be able to complete bleeding the brakes in the normal manner.
How much should rear brakes cost me?
If this doesn't work...then yeah...the master cylinder is probably bad.
Hope this helps
i think it will be ok

You got it!!it is the master cylinder.

you may have air in your master cylinder as well and you will have to bleed it first then go on to bleeding the rest of the system not just the one line.How much does it cost to replace a fuel pump on a 1996 Ford Contour?
This occured on my car, after I replaced the rear brake lines. If at any time, the brake pedal was pressed while the system was drained, the piston in the master cylinder may have pushed out too far. Trying to bleed and repressurize could have ruptured the master cylinder's seal because of this. If that is the case, you will continue to see air bubbles, and fail to build brake pressure, as the fluid is bypassing the cylinder due to a damaged seal.You will either have to purchase a master cylinder rebuild kit to replace the damaged seal (it comes with a new spring as well), or replace the master cylinder with a new/rebuilt unit.

I hope this answers your question.
There are TWO reseviors in the master cylinder. Are they both full.
How to tell which is the hot wire?
Just keep bleeding them and topping off the resevior.

One good thing about brake fluid is that it will seep from any crack or loose fitting.If the master cylinder is full it would be hard pressed to introduce air unless it is leaking past the master's piston's into the booster itself.
My guess is that you totally emptied the system while doing the repair.
Bleed all the wheel's.
Try not to use the pump up method.
With an assistant, open the bleeder and have him/her push the peddle down and yell down when it no longer moves any more, then tighten the bleeder and yell up, indicating that your assistant should let the peddle back up.
Repeat.
it is possible you droped fluid while filling the master.if the master cyl went dry while fixing the line. you fill the master again open the bleeding nipple and let fluid flow until there is no more air .close the nipple take a clear plastic hose fit it onthe rt rear wheel cyl nipple put hose into clear bottle with fluid submerge hose have some one pump brakes for you and bleed system next wheel should be left rear right front then left front. there are different machine or system to do this job which is going to cost good luck
no heat in car but guage skyrockets?
im thinking yu have tightened up any connections at the master clyinder also if you had let the cylinder go dry you gotta bleed it. ok then you need to keep plenty of juice in the cylinder there are 2 resivors. go to the wheel that is furthest from the cylinder, but first pull the drum on the replacement brake linings look at the brake cylinders pull back a boot not off just take a piece of it and peel it back not off if you get any fluid coming out of it you have a bad cylinder check the other side of the cylinder if it is good look to see if the piston push rods are set right if they look cool button it back up,, have some one get in the car pump it up and you open the bleed bolt. well you know how to do that retighten pump open hold down tighten untill a stright shot comes out tighten go back to the cylinder refill go to the rear drivers side same deal then front pass then drivers side you should have pedel just dont let your cylinder go down. If you have abs then you may need to vacum bleed them your shop has one. all else fails new cylinder.. ALWAYS go to the easist thing first and work up. how come you only replace one wheel brake linings?? maybe i misunderstood. good luckits the master cyl, becuase everytime you get on the brakes more fluid pushes out
