I just picked up a gauge from my local parts store. Going to check it tomorrow. I did those very tests you’re speaking of last night and the pedal behaved as if the booster was not leaking. It’s a hard pedal every time; 1st, 2nd, etc. My dad was searching for available boosters for the car online and said there was 2 different ones that fit it. One has less boost than the other. But apparently they have the same bolt pattern and look the same from the outside. They have different diaphragms. We are thinking maybe this car has the weaker one. Like the booster is operating but perhaps not generating enough assist. Not certain but we think that may be what’s going on.

Thank you! Yeah, I’ve talked to Aaron a couple times. I put in the vacation hrs. request at work already lol. I’m planning on driving it there! Can’t wait!!

Looks to me like all four are indeed locking up.

There’s more! I got two spare rally wheels, another driver side remote mirror with the toggle and cable, 4 chrome rims, service manuals, assembly manuals, even the Fisher Body manual for 1972!

Some cool stuff I got with the car as well...

I got plans for donuts! But it’s got an open diff currently. Am purchasing a limited slip from a buddy of mine. Will get that put in before long. Can you even do donuts with a one-tire fryer? Lol

Excellent! Just sent the email with my info and paid the dues on PayPal. Thank you!

Thanks Rob! I haven’t done the gravel test but I sure can try that. There are oodles of gravel roads where I live! Also, I sent you an email several days ago. I’d like to pay my dues. Aaron D. told me to get hold of you. I’m in Utah and I’d like to attend the Western Meet in OR this year.

You guys like pics so I’ll put a few that I have so far here. Thanks! 1972, Sequoia Green, painted top, 402/TH400, 3sp/console, bucket seats.

Thanks you guys! That gives me some ideas to look at. Going to start with a gauge so I can get a reading and adjusting the drums/shoes. I don’t imagine the parking brake has been used a lot. I can get into the habit of using it to keep the rear brakes adjusted afterwards. Also, I can definitely bleed the lines and make sure there’s no air. I’ll report back in a couple days when that stuff is all done. Again, love the group and appreciate your help!

Yeah, it does have a cam. And I hear you on the pedal indicating the booster may be bad, but it does hold whatever vacuum it’s creating. I’m kind of thinking it just might be less than the 18lbs. I don’t have a vacuum gauge I can test it with to see what it’s pulling. I’ll see if I can get one from my parts store.

jft69z, I just got the car a couple weeks ago. But so far it’s been this way since I received it. There’s been been a massive amount of work done to the car. Basically every part I can see under the hood and under the car is brand-new. Even the actual brake lines are new. New doesn’t mean everything is right, I’m just saying previous owner did a lot of work and all appears to be quality work!

Tube is clear of obstruction, check valve is working, I tested it separately. I took the compression nut off of the tube and cleaned the Teflon off. Then cleaned the adapter. Started car without the line hooked up and the carb is drawing a massive amount of air. Sounds like a jet! Reassembled without Teflon (because it’s a compression fitting) and so I believe it’s all sealed and connected properly. Calipers look new, pads and shoes are good. Rotors and drums are good. The brakes do grab and stop the car, it’s just very hard. I picture my great grandma driving this car as she had one in the 70’s. And there’s no way she would be able to stop this car. I can stop it because I’m strong enough to push the pedal hard.

New member here, first post. I am having an issue with my brakes. Carburetor creating plenty of vacuum, no leaks in the line from the booster to carb. Check valve working properly and the booster does seem to be operating properly and holding vacuum as verified by testing the pedal. Yet it is very hard to stop the car. I really have to press down the pedal hard to get the car to stop. Is it possible that the booster itself is the incorrect booster? Like maybe it’s working but just under capacity required for the car? Any thoughts or ideas would be welcomed and appreciated, thank you.
