Brake caliper guidance

I'm hoping one of you guys or gals might be able to provide a little guidance for my situation.

I needed(wanted) to rebuild my 944 rear n/a brake calipers so, silly me, I though I would disassemble them and paint them. That went well, however, upon reassembly, I cannot figure out how to overcome the spring that holds the caliper together. There's got to be a way.

Any help would be appreciated

If they won't slide, and there is paint in the slide rail grooves that may need to be removed and the grooves/rails need to be greased with caliper grease.

I very carefully masked those areas off, and in fact, all areas where any two parts interact, so no paint related issues. The spring is just very difficult to overcome and I've been unable to align the part that bolts to the car with the other section due to the spring pressure.

H2OSB - I did the same and had to figure it out. First off, congratulations on not breaking the springs where they insert into the caliper body.
Are you comfortable with the required orientation of how the “hydraulic section” needs to fit with the “frame section”? If not, Google some photos. Then- and I’m not trying to sound glib - you just manhandle them back together, using a lever to help lift the spring sufficiently to allow the two parts to once again cojoin. It’s been 18 months since I did mine, but I recall being able to get it done without needing to call in extra hands. I realize this isn’t the world’s greatest explanation, but get them oriented properly and push them where they need to be relative to one another. IIRC, each spring only contacts the “frame” in two places, so remarrying them isn’t difficult once you figure it out. They are strong and chunky parts so it’s unlikely you’ll break anything. Just don’t try to remove the spring.
I hope that helps?

There is pretty good DIY guide on rebuilding the rear calipers on this site: Dwayne's Garage

To get the springs and plastic guides in is not easy, but it can be done.

Thank you guys!! This is exactly the info I was looking for. On a couple attempts I could get one side in then would knock off the little plastic guide when trying to do the other. At that point I stopped to see if I was going about it correctly.

This job is a knuckle buster but a methodological approach worked for me.
Oh, and a few swear words!!!!!

This is a very good write-up.

I looked at that write up. I agree its an excellent resource. I was hoping there was an easy way, but since it appears there isn't, I'll get my swear word dictionary out and have at it.

Thanks all

When I did mine, I used a bench vise to help out. If you take it slow and (as said above) methodically it is not that frustrating.

Here's a couple of reference photos for you.
This was just after my caliper rebuild. Before I changed over to the turbo Brembo 4 piston calipers.
Good Luck

I used C clamps to reassemble

As mentioned in the referenced "Dwayne's garage" link for disassembly I used C-clamps to hold the springs down and in place for reassembly. Once the two parts were started together you can remove the clamps and push the two caliper parts together all the way. I also had a helper for this step. Good luck.

I followed that guide and used C clamps as well and got them together. Thank you very much everyone!
