A Novice Bleeding brakes ???

[markiemyster]

I converted my 65 master cylnder over to a dual system. Before I did the brakes always took forever to bleed. Now that I have a dual system I thought it wouldn't take so long but it still takes hours. I start at the drivers front wheel , then the passengers front, then the drivers rear wheel then the passengers rear, then back to the same rotation and it seems like I do this over and over again and still can't get the brake peddle up where it should be.
I'm not much of a mechanic but my buddy is and he has done tons of brake jobs. He usually bleeds while I pump. He says he's never had this much trouble before on other cars.
Does anybody know what the problem could be. Are we doing something wrong or is that typical.
We spent 45 minutes today and 45 minutes a few days ago and still have very little peddal.
We've also used a hand pump unit and that doesn't seem to speed things up at all.

OPEN FOR SUGGESTIONS @#$%^

OK what type of fluid are you using? If silacone how did you flush the old style out?

Silacone gets airated very fast! That means it hold the air in it.
First thing is disconect the the lines off the master cylender and get an adapter from the port to a hose then blead the cylender into it self.Rember each time you pump it will try and squirt out the top so real light like blead the master cylender

ALWAYS MAKE SURE ITS FULL OF FLUID

I then gravity bleed the system starting at the furthest away then closer.as I am gravity draining I whack the calipers with a rubber mallet to get any air trapped in the crossover ports moving,Then once its gravity drained all fluid coming out of all calipers I walk away for at least 4 hrs. to let all the mircroscopic air come out of the fluid.

Next again making sure I am full at al times I start at the furthest away and go 2 cycles of pumps all the way around the car MAINTAINING A FULL MASTER AT ALL TIMES. then agin walk away for 4 hours at this point the brakes are allmost perfect.I then repeat this process one more time and I am done

Good luck if you just keep pumping them when there is air in the lines it just airates the fluid and you never get it right ,Once they are bled it stays bled

I'll tell you what saved me when I bled my brakes. Replace the bleeders on your calipers with the type that have a check valve in them. That way you can pump away without opening and closing the bleeder, and no air can be sucked back in the system. They are available at most auto parts stores in various sizes. Take one of yours with you to make sure you get the right size. Also, I'm not familiar with the 65, but on 68 and newer the proper sequence to bleed brakes is: LR, RR, LF, RF. This way you start furthest away from the master cylinder and work your way closer. One last tip, use clear bleeder hoses. When you see solid fluid coming out of the bleeder, with no more air bubbles that caliper is done. You don't have to keep pumping until the hose is completely full of fluid. I got clear tubing at The Home Depot. I bled my brakes by myself and only did each caliper twice (once would probably have been enough) and my pedal is nice and firm. Hope this helps.

I more thing drain a bottel out of fluid and let it sit for awhile if the fluid is mixed you will see like oil and vinager seperation and then you need to gravity drain untill all the old stuff is out .allthought silacobne fluid is exspensive I never reuse hwat I have drawn out of the system in case it is contaminated.Also because it gets airated
