Parking brakes shoes

Follow the FSM procedure. These shoes rarely need replacement, because they don't wear out unless you drive with the parking brake engaged.
Some generic special tools, for the weird springs, can be helpful. There are some generic drum brake tool kits that may have useful items. You can use pliers and screwdrivers instead, but it will take longer and increase donations to the swear jar.

Do you have the FSM pdf?Follow the FSM procedure. These shoes rarely need replacement, because they dont wear out unless you drive with the parking brake engaged.

Any tools pics for reference ?
Look at these:
Drum Brake Spring Pliers Kit, 3 Piece
The spring pliers are your best friend when it comes time to get the spring(s) hooked back into the shoes. I think. I haven't done parking brake shoes in a long, long, time. Buy the brake kit from the dealer and you'll be pleased with everything it includes.

Here's a discussion on the tools for the rear brake shoes.

Rear Brake Shoe Tools | Brakes, Suspension and Steering
I am planning to do rear shoes on both E420s. I pulled the rear tire and rotor off and noticed that I need a tool to compress the spring that retains the shoes. Actually there are two tools. The spring compressor is 112 589 09 61 00 ($41.40) and the spring hook 116 589 01 62 00 ($12.00). I...
Click / tap on the link in my previous post, scroll down a bit... then click/tap on the desired procedure. I think 42-0530 is what he's looking for?
One mm
Have not started the other side
Basic, but worth checking.
Have you compared the old shoes to the new, for exact circumference and design?
Is there a ridge on the outside of the drum? If so, check to make sure the ridge is not accumulated rust/debris.
Have you checked that all cable ferrules are seated properly, and the actual foot lever is completely released?
If you have not started the opposite side, I would do so. It may provide insight.

You should be able to ascertain whether the shoes are completely reduced to their smallest physical circumference. If so, and there is no accumulated rust on the lip of the drum, this would indicate improper manufacturing tolerances. This could be shoe material thickness or casting intolerance where metal portion of shoe contacts adjuster or opposite end. I'm doubtful, however you seem to be close to this explanation.
Obviously, things should not be this tight, and even if you get the drum on you may have issues with brakes dragging. Is there any significant ridge on the drum?
Right side cable should not be tight with P. brake released. I would inspect the opposite brake.

Use FSM 42-0228 (Checking, Removal & Installation of Brake Discs on Rear Axle) & FSM 42-0530 (Removal & Installation of Parking Brake Shoes) for procedural guidance. Not every step is necessary.
The Harbor Freight drum brake tool kit will not work for E500E parking brake shoe replacement. It is meant for actual drum brake shoes as found on older vehicles. These shoe types are greater in size. The HF tools are too big to fit any access hole for star adjusting or installing/removing the retaining springs. The pliers are also light duty & under heavy use will fail at the pivot point (I “consumed” a pair during a period of time when my Snap-ons were MIA. I have since found the 50 year old Snap-on pliers & they are still going strong).
The proper tools can make all the difference in a happy, timely job completion. I do not have either MB special tools 116 589 62 00 or 112 589 09 61 00. I discovered that pliers with a 0.25”(6.35mm) jaw width did a very good job in quickly removing/installing retaining springs (107).
Regarding retaining spring (107) installation, I used a paint pen to draw a line across the coils identifying the location of the hooked end. This lets me know while compressing/turning the spring when it is properly seated at 90 degrees within its slot.
Once the shoes were installed, I grabbed the entire assembly with my hands & manhandled it a bit to make sure the components were fully seated & secure.

I'd agree with that. My man fitted a complete NOS MB kit that I had in stock. We've kept the old lot as it looked good and probably fits my son's 190D 2.5, if he ever needs it.

I would recommend Uncle Kent's tool set for doing the parking brake job. It definitely takes the "dread" factor out of doing this, and actually works quite well.
I don't believe the factory tool for this is even available from MB anymore.

Interesting. I've had one of these tools in my box for years and didn't know what it was. At my age I have replaced many shoe-in-drum brakes and always just made do with pliers and levers which would frequently result in crawling around the garage looking for springs that had jettisoned.
