Brake piston grease

[cober]

Did some brake job. Brake pistons was too tight, then I greased them.

No! The brake fluid provides the lubricant for the piston. You should either clean/rebuild the caliper (if not scored) or replace the caliper. There are so many things wrong with this video I don't know where to begin.

Assembly

4. CAUTION: Do not use anything but clean brake fluid to lubricate the caliper pistons, seals and caliper bores. Use of any other lubricant may cause premature failure of brake components.

Lubricate the caliper bores, new piston seals and the caliper pistons with clean Ford High Performance DOT 3 Brake Fluid C6AZ-19542-AA or equivalent DOT 3 fluid meeting Ford specification ESA-M6C25-A.

Not from a tattooed, shirtless Russian (guessing) wearing a cowboy hat... LOL. When in doubt... RTFM.

Working in the grass with just a jack and no jack stand supporting the vehicle?

Yeah I noticed that too, but he did have a nice piece of log to work on. Did you notice the bright orange rust on that caliper. That sucker got really hot.

 

[shucker1]

Yup. Wonder what the rotor run-out looks like?

I guess the log was the jack stand?

Good for a laugh, a video of what not to do.

I cringe when I see people disturbing filthy parts, opening up the seal between what should not be exposed to atmosphere, and all the filth/dirt on the outside of those areas. You should begin, start, every time by cleaning the area surrounding critical clean/grease areas. That's why I never take the front caliper bolts off on the brake design like these 2nd gen's. I pull the bracket to spindle bolts, and leave the caliper bolt/boots undisturbed. Those can go untouched for 10+ years easily, replace the grease if the seal is broken or too old.
