Ken, I believe Service Motors still has the complete service manuals.

An old Service Motors manual that I keep next to my chair still has the overview brake diagrams and adjustment section but no detail pictures of how the shoes and adjusters are assembled.

Here is a picture of the 6" brake display from the Nationals, I don't know if it shows what you need to know or not.

Ken, my 1948 CC had two different styles of mechanical brake, three of one and one of the other! The backing plate, actuators, brake shoes, and springs are different for each style. From the outside, both styles look similar and work the same - the cable pulls on a lever. But one style offers more adjustment than the other. (It's possible I just didn't figure out how the oddball worked.)

Here's the version I prefer. Notice the actuator at the bottom. The lever on the back works a large round head with a wide slot cut across the head. The slot contains two angled actuator shoes, which are held in place by a T-head bolt with angled faces. The back of the bolt projects through the lever on the backing plate. By turning the nut on the end of the bolt, the angles on the T-head push the two little angled actuator shoes in or out, giving you an adjustment as the shoes wear. The actuator shoes push on the brake shoes. Externally, this style can be identified by the nut at the base of the arm on the back of the backing plate.



Here's the other version. I think the actuator is at the bottom again. This time it is round with a slot around the edge of the head that captures the ends of the brake shoes. The bottom of the slot is elliptical (I think) and forces the brake shoes out when turned. There is no way that I can see to adjust this brake besides adjusting the cables. Externally, this style can be identified because it doesn't have a nut at the base of the arm on the backing plate.



Again, parts from one system are not interchangeable with the other. You have to swap out the whole backing plate to change systems. I went to Nationals and combed through the vendor's piles to find the backing plate and parts I preferred, then swapped it out on site.

Have fun!

One other note - I bought new brake shoes at Nat's for my new brake. When I installed all the parts and put the wheel on, I couldn't adjust the brakes enough for the wheel to turn. The new shoes were too thick! Service Motors kindly let me return them. I then found thinner used shoes in the vendor area and swapped them on. No problem.

The mechanical brakes, when adjusted properly, work just fine. You do need a strong leg to lock the wheels, though!

Hi Park,

 I have the same problem with the new shoes, I can't get the brake drum over the new shoes with the adjuster nut drawn all the way out.  The new lining  has a uniform thickness around the shoes.  The lining should have a taper on them.  I believe the lining should be thinner in the middle of the shoe.  There is a machine that will sand off the shoe lining to the proper thickness but I haven't found a shop with one yet.

Gentleman, if you are having issues with the brake shoes you received from service motors please let us know as soon as possible, we will take care any concerns you have.

Dale, this was a couple years back. Since I was at Nationals and I was in a hurry, Butch took ‘em back and I just went to the used parts. Under Butch and you, Service Motors has always really done a great job with the “service” part of the business. Thank you!

Park
