Almost no brakes

[davethepackerfan]

Guys,
Back to work on my project 81. The next thing I'm attacking are the brakes. The pedal goes all the way to the floor easily, and then stops poorly when I crush it in the floor. The car pulls to the right significantly when I do stop.
The power brake booster does not have anything hooked up to the grommet on the front. From reading through some old posts, I know there should be a check valve there, and then a vacuum line to the back of the carb. So I bought a check valve and some 3/8 line. Does this hook up to the hard line/tube coming off of the back of the carb? Any suggestions? Thanks,
Dave

If I remember correctly it hooks up to a fitting on the rear of the Intake. You should have full manifold vacuum.

I hooked up to the hard line coming off the back of the carb. After starting the car, I hit the brakes and I get nothing, almost no resistance from the pedal.:confused

Your booster has nothing to do with this problem, unless somebody removed and played with the pushrod.

Have you tried bleeding the brakes?

 

[davethepackerfan]

yes, I bled the brakes first - sorry, I should have included that in my post. There was alot of air in the system. Also, the right rear caliper has a small leak

as long as you have a leak you will not get a good pedal, also check your lines .
I am replaceing all the lines on my 76 to fix a simular (bad brakes) problem; everything else (except the booster) is new, but the lines are in bad shape.
