How do ya push the pistons back in the 4 piston sumitomo's?

I'm a little late to this thread but installing pistons in a clean caliper should be able to be done with FINGERS ONLY! No clamps or tools needed. If you do use tools you may risk damaging the pistons or the caliper bore. DO use some brake fluid to lube the piston and seal when assembling. There is also a caliper rebuild lube out there but I have not ever seen any on auto parts store shelves.

A light coating of rubber grease works wonders.

I have no idea what "rubber grease" is but NO PETROLEUM PRODUCTS can intermix with brake components.

It's not rubber grease it's called caliper slide grease or something like that.

Caliper slide grease goes on hardware.

True but I have seen mechanics use a light smear of it on the piston when pushing back in after servicing...... maybe you shouldn't do that hahaha.

G clamp worked a treat guys.
I mean I used to do it with a G clamp all the time on my twin and single piston brakes but I think I overthought the process this time and didnt think of using the clamp again.
Pistons went back in without a hassle at all.
Hubs are coming next week and I should, well AFAIK, have the first 2nd gen magna with 3000GT VR4 brakes on it!

I just broke down my front TT calipers yesterday and used the long screwdriver method for pulling them out. worked like a charm. I'm getting them powder coated right now and should be reassembling them this weekend. I'm gonna try to re-insert the pistons by hand... I'll report the results as soon as i get them back.
