I am installing my new BMC, I got the back drum to bleed just fine, but not a thing is coming out when i try an crack open the front bleeder?


Whats wrong?

 

They may be plugged. Remove one completely then see if fluid comes out. Replacements are cheap...

 

your saying the bleeder is clogged? i'll try that to see what happens but is a bench bleed REQUIRED or just a good thing to do. I have no pressure what so ever right now when I try to brake.

 

bench bleed is really required, if you don't you'll be pumping all day long. I say if it isn't something wrong with the bleeder, give one pump - hold and crack the lines to the MC. Air up top can give some deceiving (sp?) problems.

 

Usually, a bench bleed is not required. What does happen is that the brake proportioning bypass valve is not centered and only one end of the brakes is getting pressure. To reset the valve, just pump the brakes a few times real hard now that you have the rears bled. It should pop into place and you should feel the pedal effort change and you should be getting pressure to the fronts. This happened to me when I changed the MC last time, but it was the rears that were getting no pressure. I think the manual says something about this but its just blurb.

 

Well, I took off the lines to bench bleed it, and there wasnt any fluild dripping from them. So I bleed it out and boy was there air. I am waiting for my buddy to get out of class so we can bleed them, and see if that was our problem.

 

I still cant get any fluid out of my front brakes? Also when I \m doing the back brakes and I crack the bleeder open the pedal drops all the way, but when I go to do the front and I crack the bleeder the pedal doesnt move.

Whats wrong? Is my caliper shot?

 

Any one?

I hate having to bum rides from my moms to go to work and such.

Edit: Sorry for the confusion, it is my car Im just at my buddy camerons(hondahater) and im just to lazy & nasty to log in an out.

 

Still sounds like the proportioning bypass valve is stuck. Maybe try disconnecting a front brake line and gently press the pedal and see if fluid pumps out. If it does then its a bleeder or caliper issue. If it doesn't then your MC or the bypass valve is out of wack.

 

I just looked at my car and it looks like the FL line runs straight out of the bottom of the MC, the FR goes through the proportioning valve, and both rears are controlled through one line. So what i'm thinking is if it was the proportioning valve, reguardless, your FL brake would have fluid. You possibly have air between your MC and proportioning valve?

What i would do it backtrack from your caliper, to the outlet off the PP valve, to the inlet of the PP valve, to the MC till i find fluid then no fluid. You could have kinked a line, gunk plugging something?

Oh and please when you bench bled your MC, were you certain you had fluid coming from every leaving line? and NOOOOOOOOO bubbles?

 

Ok I have blown the lines clean with compressed air. I have also put pressure in the MC and so that fluid shoots out the caliper. Then I did the pump and open the bleeder about 20+ times nothing.

Answer me this, when I do the back brakes and I open the bleeder the pedel drops all the way to the floor, BUT when I do the front brakes and I crack the bleeder the pedel doesnt drop any?

Here is my problem to the 'T'

This guy solved it by using a "mittyvac" What in the world is that?

Have you removed the bleeder and checked it isn't plugged, just unscrew and inpect, you can blow through the beeder from behind if it works.

 

Yes,

I decided to take back the Master Cylinder and get a new one, I also picked up a set of Russel Speed Bleeders. I am going to start new again on this. I will do everything by the book.

I will blow out all the lines make sure nothing is blocking them, and also to get out all the old fluid.

Bench Bleed and install the new Master, then I will bleed out the back, and hopefully the speed bleeders will help me to bleed out the fronts.

If not I will have to I guess maybe brake down and for the first time in my life bring it somewhere.

 

so you pressurized the MC with air and fluid came out the front calipers with the bleeders OUT? thats your answer.........

 

I also did it with them in, I know I got excited at first too!

 

Well I just got back in from working on it and.......... IT WORKS!!!

I dont know what was the cause of it. I went and got a new Master and Ordered some Russel Speed Bleeders, Which I LOVE! I will use them on all of my cars!

I blew out all the lines with compressed air to clean it. I bench bleed the Master, installed that, Started from the back and worked my way forward. I waited until the fluid was nice and clean. Everything works great now.

Thanks for all your guys help. I dont know what the real problem was, but I got it fixed so thats all that matters lol

 

Grit in the fluid, glad it woks now, Russell bleeders rule.....
