Rear Drum Brakes / 97 Mercury Mystique Sign In

I'm changing brake shoes on a 1997 Mercury Mystique with 14 inch drums with 39,000 miles. I pulled one wheel first, and noticed the rear facing shoe was very thin compared to the thicker forward shoe. Assuming there was unequal wear, I purched Wagner-Thermo Quiet replacements. Much to my surprise, the Wagners are the same. Thick forward shoe and thin rear shoe. My Ford/Mercury service manual says to replace shoes if they measure less than .125 inch and makes no mention of different shoe thickness....

The new Wagner rear facing shoe measures .136 inch, barely 10 thousanths over the minimum?

1. Is this some weird drum shoe design from the 90's? Every shoe I've ever replaced had equal thickness shoes, so who knows about this vintage car and it's brake design?

2. Is there a specific brake tool (part number) to remove the springs? All my brake spring removal toools used for my vans have no possible use with this design. Grabbing with pliers doesn't look like it would work either and possibly damage the springs.

I'm partially answering my own post. I called Wagner and their minumum thickness for the shoe is .030 inch so it appears The existing shoes are well above the minimum specs.

Still need to know about the brake spring tool for this car and if this shoe design is commonly used?

Thanks,

They make a tool but a large screwdriver usually works fine.
