Wolf, I have two sets of shoes. One set has primary and secondary shoes; the others are the same size. I installed the primary/secondary set on the front and the set that is the same size on the rear axle. I guess it depends on where you get them relined.

I bought NOS shoes and they are like Don says. I also have NOS linings on the shelf and they are different lengths also.

Does it matter much? Don't know.

I know that for decades working on drum brakes, the primary or short shoe went towards the front of the vehicle. Not sure of the engineering. But my other shoes are of the same length. Since the front brakes do the most work, I put the primary/secondary shoes on the front. Believe me, my truck will stop very quickly with my single master cylicnder and standard (not power) brakes.

Just my experience, not a recommendation ...

If you look in the online maintenance manuals, the brake section tells the long short part...so does the Quirks manual...

Quote:
GIVE ‘EM A BREAK
Brake shoes on your 5-quarter are different from what you’ll find on other tactical wheeled vehicles — the front, or primary, shoe in each wheel has a shorter lining than’s on the rear shoe. Make sure you install ‘em that way— and they’ll give you a brake.

Hallo together,
when I first time rebuilded my M715, the lenght of the brake shoe lining was front and rear the same. Technically this makes sence, for it is a duo-servo brake, which forward and reverse supplies the same brake force with the same brake pressure. The only problem with this brake designe is the variation of the friction factor of the brake linings. Therefore it is very difficult, close to impossibel, to set the brake forces on the brake roller test bench to the same braking forces.
When you get your brake shoes relined, always install per axle a new set. Else your problems with brake drag will never stop.

May be the brake shoes you have installed are fron a Gladiator truck. The so called simplex Brakes have differnent length of the brake shoe lining to avoid overbraking of the rear axle. To avoid his problem I installed 15/16 rear brake slave cylinders. Since then I have a real good stopping power.

Using the TS60 NAPA shoe info above I found this...

Brand:RAYLOC
Part Number(s):TS60


Try that and let us know if it works...

My NAPA comes up with nothing for a TS60, trying the TS320 also mentioned today. Chevy P30 van cross. Mikel just gave me the skinny on a relining shop that is pretty close (in Portland CT) too...

Maybe I missed it, but did anyone give an application for the #451 autozone shoes?
