What is the procedure to tighten up the parking brake? I received my repair manuals today and they don't specify anything regarding the parking brake.

 

The way it is now, it's not doing me any good.

Sorry I say it in my tag line so I thought I put it there.

Loosen the lock nut on the adjustment screw on the drivers side of the band and turn the screw in or out until a clearance of about 1/32 of an inch is obtained. On the passenger side there is an adjustment nut on either side of the split in the band.  Loosen the lower lock nut and turn the adjustment nut to obtain 1/32 clearance and repeat with the upper (long) adjustment nut.

I am finally looking into this brake good. I can't find a diagram of the parking brake so I'm still scratching my head a little. I think I understand what dictator27 is saying but not quite certain. Attached are some photos that I took last night. 


One thing that I did notice is the band material for the brakes is very brittle. It seems to be like cork or something not quite sure. I know this needs replacing but where can they be gotten?

Attached are the parking brake adjustment procedures from Book 2 of the Studebaker Service Manuals (with supplements).

 

These are pretty much the same as given above, but thought the illustration might also help.

Is there a place in the book that tells me what parts the letters are in the illustrations?

The first attachment has the instructions which tell what the letters in the illustration are for, however I can't seem to open it. If you can't open it let me know and I can email it to you.

I can open them just fine. And I realize that the illustration letters go along with the illustration, but I was also interested in knowing what is labeled part is actually called.

And also, would you happen to have the instructions for replacing the parking brake band woven material? I have just the woven material coming in the mail.

Sorry, I couldn't find an article about replacing the brake lining specific to your car, however there were articles for a similar (but not identical) lining replacement on earlier cars. The problem is it requires a special jig to form the lining to the band and finding one of those jigs today would be difficult. Perhaps someone else could chime in as to how it should be done.

I would think a jig could be easily made.

I now have the material, I just need to find the instructions. I have looked up several Dykes manuals, but I have yet to find the correct instructions. I also haven't seen any mention of a jig.

Any Dykes manual from the 30s or 40s has the procedure for replacing woven lining.  Pretty much seen one seen them all.

Do you know of a place that has these. I have looked but can't seem to come up with what I need for certain. I'd hate to spend money on a book and then it not have what I need. I don't mind spending the money if I know it has the information that I need.

This is from Dyke's 1937 18th Ed.

Spinneyhill,

 

Thank you for the images. I have been looking over them, but I don't anything mentioned about a jig like was mentioned above. Also, would the Parking Brake band be more similar to the external or internal band?

The parking brake is a contracting band, so most similar to the external band.

 

Maybe the poster of the jig idea could elaborate?

The 1927 Studebaker Service Manual indicates that a "jig" be used to hold the brake lining to the brake band when installing new brake linings on externally contracting brakes, however it appears the Dykes Manual (copied above) provides an alternative method of installing the lining without the use of a jig.

 

In the situation above I'd question the need to replace the lining, which involves a fair amount of work to remove, disassemble and reline the parking brake. I'd suggest first trying to adjust the parking brake as outlined in the service manual. The old brake lining material may appear brittle, but it's likely an asbestos composite material which was brittle to start with. Keep in mind this is not the service brakes and would get limited use as a parking/emergency brake anyway.
