HELP !! Bleeding brakes
I have replaced my master cylinder and have been trying to bleed my brakes for the last hour and they are terrible. My wife is helping me so now I'm yelling at her at no fault to her. I'm using a Mighty-Vac and the rears are fine as it pulls the fluid through the rear master cylinder but I think it's the fronts giving me the trouble. I'm getting very little fluid to come through on the fronts and it's barely using any out of the front of the master cylinder. I now even have a brake light on in the cluster. I did bench bleed the master but not very well. Please help I don't know what I'm missing. Also I tried having the wife push on the brakes bleeding that way and got very little fluid to come through any of the calipers??? This is on my 82 by the way.

I've been researching bleeding brakes to prep for work on my car. Hopefully this thread that discusses the proportional valve will be of some help:

I found this one had some great information as well:

Both very good articles. I took off the master cylinder again and going to bench bleed it again. Then I'm going to buy the Power Brake Bleeder from Motive Products and try that. The brake system worked perfectly before I removed the MC, I replaced it for looks along with the booster.

There may be other issues as well but save yourself and the wife the aggrivation by installing speed bleeders on the calipers. They take the second person out of the bleeding chore and make the entire process so much simpler. The are cheap and the work... a rare combination !

get (or make your own) a pressure bleeder...
Bunches of ideas below. One of the best things I've done. Makes bleeding a lot easier. I used to dread having to do it and now I only dread the time of having to remove the wheels.
I made my own because I didn't want to order and wait for one.
I made mine out of garden sprayer and use and aluminum plate and a c-clamp with a rubber gasked to seal the master cylinder. I planned to order a real one later, but it works so fine that don't need to order one. I use a pressure gauge on the tygon line to keep the pressure between 10 psig - 20 psig.
See the thread below:

There's a cool idea in that thread about using a shop vac to draw the brake fluid out via the calipers.....might want to try that (just make sure you don't let the master cylinder run dry).

Looks like a worthwhile investment.

You attach the plate to the top of the master cylinder and secure it until it seals. Brake fluid is poured into the resevoir and it is pumped up to 10-12 psi. Then you basically crack the bleeder on the calipers until you get clean fluid and no bubbles. Super easy and it works great.
OP. Bleeding order is the following:
Rear passenger (inboard bleeder then outboard bleeder)
Rear Driver (inboard bleeder then outboard bleeder)
Front Passenger
Front Driver
Good Luck. Do it in that order, re-bleed your Master and you're brakes will be great.
