want to paint my calipers and am trying to make sense of this step - anyone have tips on removing the calipers?

 

Don't really understand your question. Check here

The servicemanual says to drain a small amount of fluid wjth a suction gun from the master cylinder before removing any brake caliper. Can anyone help me understand that step or if it is necessary?

 

Why not just remove the wheels, spray clean the brakes with Brake Clean or something alcohol based, wire brush, mask everything off, then spray the calipers with VHT paint in a rattle can. You only need to paint the outsides as the insides never show anyway

All masked and painted with a rattle can

Prepped and ready to paint
. That's what I did. Careful about over spray. Great finish, unless your going for 100 points in a show.

 

I'm more interested in doing a thorough job with the por15 system
unless of course your paint has held up? How long has it been since you painted and how often do you drive it?

 

When you push the caliper pistons into the caliper to get them loose it displaces brake fluid in the piston bore into the master cylinder reservoir.
So you drain or suck some brake fluid out so that it does not overflow out the top and make a big mess.

 

Hi Coty49; I painted them in June and its a daily driver. Off the road from November to April. As long as you really clean the calipers and wire brush them the paint should stay. I used VHT Caliper Paint. Just pulled the wheels again to restore the rims and all calipers are like the day I painted them. I also painted the edges of the rotors for a little different look when the wheels are on. I also cleaned off 15 years of dust and road tar from inside the wheel wells. Plan to touch up the paint on them as well using my airbrush. Got a perfect paint match from the PPG Dealer. Clean up rotor over spray with a blade and some lacquer thinner. The VHT paint is available in different colours. Couldn't see spending 1000 bucks for painted rotors.
