Hi,
My stang has been sitting for about 9 months...brakes worked just fine before that ( although always had a slight pull to one side).
After a lot of help from this form and rebuilding some parts myself; I finally took it into a shop to confirm my work.
The car, after a carb rebuild; ran quite well.
But I noticed that the brakes would have a rubbing/slow rubber style stopping sound.
I wasn't sure what to do. I did not have this problem ever before.
There is no screeching noise that usually indicates the need for drum replacement.
I noticed the fluid reservoir looked quite low (no idea why) and topped it up again; but still same problem.
I have changed the drums a few times before and should be able to do it agian; but i would have no idea what to look for or what I needed to do. I was hoping that it may just need some kind of spray after sitting for 9 months.
Thanks,
Micah

if you think there were a few things that could cause disaster in the carb... then move that though right behind the tires and into the brakes...

jack up the car...  have a friend depress the brake and release it... while you see how fast each brake shoe set releases....

you could have a wheel cylinder thats hanging up from corrosion from sitting.. not out of this world to find it..

there are several articles here and in the other mustang magazines on drum brakes...

i have a few tips... look in the how to .. and in the tech section... or type Drum into the search window.. or something like that..

it will take me the better part of an hour to type out what i know about mustang drum brakes.. and the issues..  perhaps in a day or so.. the sun has not come up yet..

thanks Wayne...will go through all of those. I've changed the drums a few times so I will go through all of the procedure again and follow up on all of those links. Just was hoping that this may have been common and an easy fix from sitting too long....most likely some sort of corrosion though and replacements needed.
Cheers

I just completed a front brake job on my 65 mustang for the same reasons that
you describe above-when you remove the tires look for signs of fluid leakage; the brake pads soak up the fluid and lose their friction ability; also, if one tire pulls to one side it means the internal brake cylinder pistons are seizing up since corrosion already set in; you have two choices- replace the brake cylinders which I did or remove the cylinders, disassemble them, clean them with steel wool and put them back together- also check the two rear brake cylinder lines to make sure they are not corroded and leaking.
One more thing: wash the brake shoes and all hardware with soap water including the interior race of the brake drum-
