Hi everybody,
I need some help with my 1965 Baracuda.
The brake pedal won't return after being pushed it. It return for about an inch, but not all the way.
There are two springs on the inside of the firewall, but one of them seems out of place and I don't know how it should be.
Could someone please provide a picture of how it looks on your a-body.

I'd be grateful for any other ideas about the brake pedal ont returning.
Thanks.
 
I don't believe there should be any springs in the car for the brake pedal. Your pedal or master must be binding somewhere. I would check your pedal bushings. Could someone installed the springs to help fix the pedal issue in the past and its getting worse?
 
There's this spring but i'm not sure it's supposed to return the pedal all the way. I have a 67 b body that has that spring on it.

Brake Pedal Return Spring and Seat

Anyone have an idea where I can pick up a new brake pedal return spring and the corresponding seat? Mine is FUBAR.

There is a special "shoulder" bolt that goes thru the pedal and pushrod.
Often the wrong bolt, or a washer was added, or just gunk gets on that bolt, and it binds on the return.
Try loosening the nut/bolt thru the pedal. If that eases the problem, find out why it's bindin and repair it.
Don't just leave the bolt loose, fix it.
Good luck
 
Hang on, here's another option;
if the pushrod, coming from the master cylinder is adjusted too long;
the compensating-Port will not work, and so, as the friction pads/shoes wear, the pedal will naturally sink ever lower, as more and more fluid from the power chamber, moves towards the slave cylinders, with no fresh compensating fluid coming in.

I did not know this; thanks for the lesson.

Yes, '66 and earlier cars have that spring between the master cylinder and the retainer on the push rod. Usually that is enough to trigger the brake light switch. If you go to a later master cylinder, you may have to rig up one to work. The original setup had a rubber boot in the mix too and a piston retainer that held it. Most of the later master cylinders aren't able to accept that retainer and boot, but, some are. It's not a big deal, but, if you really want that sealed up like the early design, you'll have to look around to see if you can find a master cylinder that will accept it. I just transferred my spring and pushrod spring retainer to a later master cylinder and let the spring just press against the master cylinder housing.
 
I am far from being an expert on anything, just a common sense person. Is it really that big of a deal? Do we really have to get that technical here? I added a spring I found laying around to the brake pedal to make it return all the way. That was four years ago.
 
My brake lights occasionally stay on, an ever so slight lift of the pedal shuts them off. But its a nuisance. I've tried adjusting the switch and it's due to the small button on the switch not sitting/seating properly all the time on the pedal. I may look at putting a spring on it.
