So i started to take the calipers apart to get them preped for powder coat and i wondered if i have to take the needle bearing out from the rear calipers as well. the cylinder where the bearing is will obviously get masked out but im not sure if i should get the bearing out too.
Everything else is out except for that bearing so if anyone could comment on what they did and if its really necessary to get it out what the best way to do it? Ive searched for some threads but none of them go into specific detail about how to do it.

thanks fellas
Stephan.

 

I haven't done calipers but I do a lot of powder coating. The problem with leaving the bearing in would be if it would hold anything that might leak out and ruin your coating finish. Obviously the bearing itself can handle the 400F the coating needs to cure, brakes get hot.

If you can clean everything out of it and then do a pre heat for about an hour 25F higher than the cure temp, you should be fine. Let it cool, check for stains that may have shown up from fluid seeping out of the pores of the metal, do a final clean with denatured alcohol and coat.

 

I took all out and got a rebuilt kit from mazda... they came out perfect.
