Is it necessary to C-Clamp brand new caliper?

I have a 92' Ford Ranger XLT with 2.9 V6..

I am replacing rotors, pads, and calipers on my front disc brakes this weekend. I got the left side done. Is it necessary to C-Clamp the piston all the way into its bore, for a brand new caliper?

I didn't do this. But the caliper installed fine with both pads.

Is this needed to prevent the new caliper from getting stuck in one position?

Do I need to remove the caliper now and C- Clamp it to re-install?

No.... you do not need to push the piston(s) back into the bore.
They come set in all the way when new. They will come out when the system is bled.

Ok. I figured they came from the factory in the completely retracted position. Just wanted to make sure

Thanks Pete.

There is something else. My make/model uses single piston calipers with split-shell caliper pins (no nut and no bolt)

I may not have positioned the caliper pins correctly. I drove in the pins till the pin tabs touched the outside of the caliper assembly. So the tab on the other end extends further from the caliper.

I looked at my Chilton manual again. It says, "Insure that pin tabs are free to contact spindle flanks on each end of pin."

Does this mean the pins are supposed to be installed with the tab ends equally distanced from the spindle flanks? The brakes seem to work fine.

It wouldn't be any big deal to tap the caliper pins and re-adjust their position. Should I do this?

the tabs should be on each side of the caliper bracket not the caliper you can grease the side against the caliper so it will slide easier.

The pins tabs are on each side of the caliper mount (they don't call it a bracket) in the V-Grooves. Already greased.

My question is:

Are the caliper pins supposed to be installed with the tab ends equally distanced from the caliper mounts?

the tabs on the pins is what keeps them from sliding out as long as the tabs are still on the outside of the mount on both sides they can move a little back and forth if you have one sticking out a long ways its probably not holding and would probably buy new pins the rubber does degrade over time.

Thanks Alan.

I adjusted the position of the caliper pins last night. They're brand new along with everything else since I replaced all the front disc brake parts this past weekend. I notice there seems to be less pedal travel now.
