new master cylinder in, new problems

[pwrshft99]

If anybody read all most post they'd have to think I am automobiley challenged, but I swear I can work on a car.

After nothing else solved my braking issues, I just put in a MC. I bench bleed it and installed it without any problems.

Now I tried to bleed the calipers, and no fluid comes out, front or rear. The pedal is pretty firm and doesn't move at all with the bleeder open.

I checked everything out, the rear is jacked level, fluid is good and no leaks. I cracked the bleeder open and hit the brakes with the car on just to see what would happen and fluid slowly trickled out but that's all. I hope someone can help, I've owned this car a month and haven't even drove it a mile...

When I swapped everything over on the 93, I left my bleeders open for a while before fluid started to make its way to the calipers. I didn't bother with the pedal at all, because I had plenty of other things to do, but if you leave them open for 20-30 minuites and nothing is getting there yet, my bet would be that you have some collapsed lines.

They are nearly impossible to see with your eyeballs if they are collapsed inside. How long did the car sit? And when I bleed my rears, I like to put a zip tie on the brake proportioning valve to keep it open while I bleed em.

The hoses in back were collapsed and I replaced them.

I was able to bleed the car with the old MC but kept getting air. With the new one the pedal feels right but no fluid. I've had my jack under the prortioning valve the whole time, I even jack once more.

IDK pretty bummed out, nice car got cheap but can't afford to have someone else fix it.

see if you can get the jack under the rear knuckle... be careful tho... it dosen't like to sit on there very well... but just pick the rear end up a little by doing that, and it should be enough to open the valve.

Other than that, I'd just loosen the screws, keep it full and wait on it. I just gravity bled my brakes that way, like I said, I was busy screwin with other things. So when the calipers started their dripping, I tightened the bleeder and called it good.

It did take a while tho on the rears.... something dosen't sound right tho if you can't get anything out of the fronts tho.

Where at in Il are ya?

I'm in rockford. I thought something was up with the MC to start with cuz when I bench bled it nothing came out of the smaller outlet. I called and was gonna return it but the next day I tried and it started squirting fluid. It was dripping fluid when I installed the hard line.

I'm gonna crack all four bleeders and try again.


I have the jack on the drivers rear knuckle, I bled it three times before changing the
MC and got fluid to the rears
