Normally you should be able to grab the spring washer with a pair of pliers and push/turn to release it from the pin. Unfortunately, the parking brake shoes are behind the wheel hub and you can only access the washer through a hole on the hub. You will need a special tool like this to release the spring washer from the pin. This tool is similar to the one mentioned in Step 5 of the attached procedure.
Like Tom, I too wonder why you need to replace the brake shoes. They are not intended for use to stop your vehicle in motion, instead, they are designed to "hold" your vehicle in place, and so should have very minimal wear, if any at all. Unless of course they are ruined by grease or oil and cannot hold your vehicle in place.
Also take a look at these procedures...

About to tackle this job this week. The front pad and rotor swap went nice and smooth. The rears look easy but the few comments on the ebrake assembly coming apart slightly concerns me lol. I have m8 bolts and just remember to have the brake off. I just whacked the fronts with a rubber mallet.

The real pain was actually getting my tires off. I have no idea who the hell took the wheels off last (bought used), but they torqued the hell of of several of the lug nuts putting them back on. One was easily over 200 ft/lbs when I checked with my torque wrench. I didn't have a a socket that would fit the lug nut so I couldn't use my breaker bar. I had to place the stock tire iron at 45 degrees and used my jack to lift up the iron until I heard a loud *** clank. Extremely dangerous workaround and frustrating thing to deal with when trying to do a fairly straight forward repair.

If you are doing all 4 wheels it would be better to remove some brake fluid from the reservoir first.

I'm planning on changing my own rotors and pads this week. Did you have to replace the caliper pin or any other bolts when you did yours? Did you reuse your brake sensors? And last question, did you use any grease on the brake pads?

Lexus recommends new bolts. Be sure to torque correctly - aluminum bolts into aluminum calipers. Brake pad wear sensor (if not worn split through the embedded wire) and caliper pin are re-useable. Brake pad grease is nice if you have it; not essential.

Heard! Thanks for responding man. Would you happen to know the part numbers or where I could source the correct bolts? This is my first new rotor job and I'm trying to do my best to have everything I need at my house before I begin this!
