Brake problem

I really believe this is what's going on Gerry

 

I think that when you installed the master cylinders they were not properly bench bleed and you sent the air down the lines . I think you have been chasing that air ever since.

If you are going to replace the rubber hoses and the wheel cylinders leave the car on jack stands after you get done. Bench bleed the master cylinder and then start bleeding but only gravity bleed. After ALL connections and wheel cylinders "FLOW " fluid then see what kind of pedal you have.

I think with all the master cylinder changing you injected air into the system.

And this poster is right . you will use a lot of brake fluid. On the 74 Nova I used 2 quarts and on my 2003 Suburban I replaced all the brake lines and the Master Cylinder and used 3 Quarts.

Good luck. I'll bet by now your hands are really dried out from all the brake fluid.

 

Yea that fluid is kinda rough. I'm sure I got air in the system because I had to change the to lines from m cyl to dist block. But remember when I had manual brakes you had to push very very hard to get it to stop so much so I would slow down way before I had to. I'm going to bleed it again befor I change anything.

 

I know you said to start Lf, Rf, Lr and Rr. What is the reason for this way (not questioning you) only asking because all the brake performance sites say just the opposite? Thanks

 

That would be my preference too front to back, but it is probably your preference on how to purge the air out of the lines. o No:

 

I start with the wheel farthest away (right rear) and end with the left front

 

This is what we did, bled the crap out of them and I got brakes. FULL PEDAL!!! Wife said, get one of your buddy's next time my foots tired! :boring: I said yes dear thanks for helping

 

Lou you were right after a few bleeds on the first one gobs of air in there than 2nd one after a few bleeds than a bunch of air there too and so on. very little in the last Lf one but I think its all out and stops a heck of a lot easier. BTW 2 1/2 half quarts.

 

I think it could be bled one more time but they are drum brakes so won't get the response as disk brakes. But it's still better than it was.

 

Glad to hear yah got it working!
LOL on the wife, mine said the same thing when I installed my line lock, "Again, how many times yah gonna do this"

 

When SHE says that to me Mark I tell her " Until YOU do it right " . That always gets her.

 

Yea I told her last night, she never said a word :grin:

 

Best way to bleed brakes is to use a MityVac.

This unit evacuates and dispenses fluids.

I use mine to bleed the brakes, and it is a 20 minute job to do all 4 wheels.

It takes longer to take the tires off.

 

:laugh:

 

I agree on what Texas T said. I have been in your situation too so GoodLuck.
