So I've got the car running pretty well, but as I was driving I noticed some front end vibration on the passenger side. Upon pulling the wheel, I noticed the hub is not turning completely freely....the pads seem to be rubbing.

I pulled the retaining pins, spreader springs, and removed the pads and piston retaining plate. Upon doing that, the hub has no slop/play, and the wheel spins very well. So, while I realize that I should ultimately pull the calipers and send them to PMB for a full rebuild(and probably will soon), right now I would like to only replace the pads, spreader springs, and piston retaining plate. While I'm sorting the car, I'm going on very short runs on very isolated roads.

Anyhow .....my QUESTION is related to the step in both the Pelican Article and Haynes Manual where it states "Now, using a plastic handle, or a piece of wood, push both the front pistons back into their housings. " This is step before re-installing the pads. I'll take a closer look today, but yesterday I didn't notice where the piston is protruding out very much into the space between the caliper and the disc....if this make sense. So, in this tight space, with the caliper still on the car, is there a specific tool/method of pushing the piston back in? Any techniques or tools to accomplish this task would be appreciated. Thanks!

to avoid having to pull the caliper:

Scissor style:

Ratchet style

I used to have a pair of the scissor style and they worked well. Somewhere in life, they got lost. I'll have to replace them when I put my car back together as they were much easier than C-clamps in my opinion.

Can't vouch for the ratchet style but work probably work too.
