The Stovebolt Site Forums The Shop Area Engine Shop Parking brake repairs....

(I am pulling this into new thread because I think my question has changed a bit.)

Yes, I have a drive shaft parking brake. There are two things wrong...one I need to fix, the other bugs me.

If you pull the lever on the floor, it never tightens up on the drive shaft drum. I don't know if this means the friction stuff is bad...(but I can tell its old)...or if something needs to be tightened up...(can't see an easy answer of something to tighten).

The second thing is that the lever feels loose and wobbly. It doesn't slide like I would expect.

LMC doesn't have anything like this in their catalog and I can't find anything like it on the web.

Where can I get this shop manual thing, and does anyone know where to start for replacement parts? (I'll call napa to start)

For a manual, you can get one from any of the specialty suppliers on the Links page, LMC should have them, What year truck do you have? Some years require the previous year manual and the suppliment for the year of the truck.

I posted a little help in the previous post.

if it is loose when it is not engaged i dont think there is an adjustment for this the lever itself rotates on a round shaft on the trans. best i remenber. it should feel tight when it has pressure on it from being engaged. mabey you could drill out the hole in the lever and install a bushing t o make it tighter- a lot of trouble unless it is real loose. you may have to clean the area off good to see it well. one of the bolts thet tighten mine was missing so after i replaced it and adjusted it according to the manual it works great. you might be able to look at the band and see the layer of friction material mabey you could take the tran pan off the floor i had mine off and i think it made it easier. you might try to engage it and then rotate driveshaft to see why it is not holding.

I got Wrenchbender's post from the other thread and using his turn the big bolt first then the little bolt advice...I have managed to tighten up the band.

There is a little bit of the friction material left. (Question!!! - is this probably asbestos??)

I adjusted the nuts on the respective bolts and tested by attempting to turn the drive shaft by hand.

It now seems to be adjusted. I'll know better once I get it out on the road for a test drive.

BTW - I was referred to Gooch Brake in KC for parts for this type of brake. They said they could help.

Sablesurfer, I am of the assumption that all these old brake materials are asbestos, seemed to be the material of choice back in the day... I will let you know when I start coughing up pieces of my lung in 20 yrs ...Now where the hell did my asbestos abatement mask go? Just don't make any of this dust airborn and hold your breath while working on the brakes If you can find that band type e-brake material for sale anywhere(NOS, etc.), please post.
I think shop manual goes 1960, then 1963 other years after respectively, need the previous shop manual and a supplement for the particular year.(i.e. A 1965 needs a 1963 manual and a '65 supp. manual) I have found it more than helpful.
