Rear Brake Caliper Rebuild Question - Main Piston

[Martin101]

I need to do an introduction page entry but I don't have a photo of my vehicle where it's not on jackstands yet and who wants to read an intro without a photo? I promise an introduction entry as soon as I have my Fiat off the jackstands.

I'm currently in the process of rebuilding the brake calipers on a 1978 Fiat Spider. After getting the vehicle to start and idle after sitting for 13 years, the brakes are my first project in a very long list of projects for this car.

After reading the brake caliper rebuild instructions at the link below, I want to find out if anybody knows why the author didn't clean the mechanical elements inside the main piston? There is a spring, a screw for the plunger, some bearings, and a washer, along with a circular clip that holds all of these together inside the piston.

Any info is appreciated.

Thanks, Martin

He doesn't go into detail but mentions it in the assembly instructions...
"After thoroughly cleaning the disassembled parts with solvent and a brush (parts washing bath works great), we can get started on assembly."
