Which is the primary shoe - 1998 Dodge Ram 3500 2WD

Primary brake shoe is the front one of the pair and takes most of the braking load, while the secondary is the back one. They should never be reversed on a vehicle. On the rear, some vehicles have a set of shoes for the parking brake (e.g. Saab) - these may also be called secondary shoes.

It is a fairly easy job, the brakes shoes are the hardest part, It has shoes? Get the drums off, a couple hits with a brass hammer should do it. If they are stuck, you might need to reach in the back with an adj tool and close them up a bit, if it gets tighter, you're going the wrong way. If the drums are smooth, you won't need to turn them, if they are gouged up, rough, have lines in them, they need to be turned.Get the shoes off, put the new ones on, clean that mess up with the air gun, put on a dab of grease at the rub spots, pull the springs tight, put the drums on, adj the shoes out till they rub, you are all set, that is how most cars would be done, you might have a little different set up. Hope this helps.

I'm assuming you mean drum brakes as they are the only ones with primary and secondary shoes. Not all drum brakes have a primary and secondary shoes. On drum brakes with primary and secondary shoes (called duo servo systems) the front shoe is slightly smaller than the rear one and is the primary shoe. On non servo systems, the shoes are the same size -- there is no primary or secondary shoe.

The rear drum brakes:

• Have internal shoes that expand against the brake drum (1126).
• Are a single-anchor type.
• Are actuated by one rear wheel cylinder (2262).
• Have two pistons in the rear wheel cylinder (2261). One exerts force against the upper end of the primary shoe; the other exerts force against the upper end of the secondary shoe.
• Adjust rear brake shoes and linings (2200) automatically.
• Need manual brake adjustment if the adjusters are not operating properly or after the rear brake shoes and linings have been replaced.

When the brake pedal is applied, hydraulic fluid pressure forces the pistons in the rear wheel cylinder outward, moving the rear brake shoes and linings against the brake drum.
The rear drum brake system includes the parking brake mechanism. Refer to Section 206-05 .
