Guide Pins On Front Disc Calipers

I have a 2002 Plymouth Voyager with front disc and rear drum brakes. While
replacing the
front brakes, I noticed that the 2 guide pins did not match. It is the same
way on the other wheel.
Is this a fluke, because in my shop manual they appear to be identical? I am
wondering if this is why I have to replace the shoes once a year.

 

Um, what do the front guide pins possibly have to do with the rear shoes?

Is this a factory shop manual your looking at or a Haynes?

It's a factory Service Manal for 2002 Town & Country ,Caravan & Voyagers.

 

Maybe you better restate the question?

Is it disc on all wheels? Is it the shoes or the pads that are wearing out?
Front or
rear axle?
