powder coating master cylinder question

[chewychevy67]

When getting this powdercoated do i need to remove the brass looking pieces in the threads that the flares on the brake lines sit against. If so how do i remove them.

Nope, it's fine. Ive been powder coating for 5ish years, so I say that with some experience. You only need to worry about plastic and rubber- things that will melt at 350-400 degrees.

yup it will require a disassembly of the master removing all pistons and seals

[chewychevy67]

am i going to have to hone out the bore after its been through the oven or will it be good to go? what do you use to lube up the bore when you stick the pistons and seals back in? brake fluid or something else?

No, they should never see powder if you mask properly. If the two port outlets (yes, remove the brass fittings), top opening, and everthing inside the plane of the firewall is masked, then there's no reason to remove all the parts inside (piston, etc) - they should be meticulously masked off so they never receive powder. Hone should never be necessary. This is powder coating, not dipping - only the parts sprayed that are not masked will receive powder.

If you do remove the piston for some reason - yes, use only brake fluid to lube during the assembly.

i am unsure how to remove the brass fittings in the outlet ports. do i need a special tool?

[chewychevy67]

can i remove them so i can use them again or will they be destroyed and have to be replaced with new ones?

[jocko]

Just place an adjustable crescent wrench (or the correct size open end wrench) around the flats and remove as if it were a nut or bolt - you'll be able to reuse them.

im talking about the brass pieces deep inside the threads that the flare on the lind mates up to. not sure how to get them out with a cresent wrench. they look pressed in.

No way to remove them without destroying them. There is also a rubber check valve (think that's what they are) and spring under each one. The brass seats are removed by tapping them, inserting a machine screw and pulling them out. You can also use a self tapping or sheet metal screw. Odds are the you'll also damage the rubber parts.

I powder coated mine as per the above thread. I did not remove any of the seats & the like, just the seals/springs.

Still looks great with no peeling/rusting as of yet.
