So i had a 4 wheel brake job done a couple weeks ago and i gotta say it is nice to have good braking back.. :lol: wasn't totally gone but they had apparently faded quite a bit. much more pedal now and great stopping. My problem is even though the hubs were coated for rust protection they are showing surface rust like nobody's business...

 

I was thinking about getting a caliper kit and painting the calipers but now i am seriously thinking of painting the hubs as well, anyone done this?

 

what kind of paint should i use and do you figure its safe to do it on the car, i really don't feel like removing the calipers again if i don't have to...

What coating? If they were zinc coated, they shouldn't rust AT ALL. The zinc coating process is what we all call Galvanization. The zinc acts as a catalyst to work against corrosion on steel or iron.

 

If they galvanized them, then they didn't do it right or something.

as far as painting them i am talking like nothing more than the main hub part being painted black... no color involved

 

i am gonna look in into what "coating" was used for these particular rotors. cause i am not very happy i will get a pi when i get a chance to show you guys the rusting

I think a high temp engine paint? That stuff is pretty durable. I just did my fronts, and within 1 month they rusted like no other. Good luck

I thought you were talking about paint the entire rotor :eek:

anyone see any problem with painting the rotor while on the car?

 

No, but it'll be easier to do if you take it off.

so wait you are painting the rotor, or the caliper. I don't want my rotors to rust as well, but i didn't think anything would hold to the heat.

nope. in fact, if you go to the duplicolor website, they show you how to paint your calipers, and they do it while its on the car.

this is with the brush, not a spray can. spray can painting is off the car only IMO.

I want to paint my calipers but to prevent any major rust on the rotors/hubs i want to paint them as well

I have been thinking of doing this too.

 

I wanted to just get zinc coated rotors, but all of the ones I find online are ones that are slotted/drilled with zinc. I wouldn't mind slotted, but I don't want drilled again (they don't last, trust me... even the good ones don't last).

 

I don't believe I can coat them with zinc myself, and who knows how much a professional place would charge if they could even do it, so I planned on taking some of the Aluminum colored Duplicolor 1200* high temp paint and paint the center of the rotor (up to where the pad would hit), then spray the outside edges of the rotor so they don't rust either. Basically paint everything the pad doesn't touch... using my old rotor as a template to see where the pad hits.

 

On newer cars the hubs are coated and the brake pads are aligned to the very outside of the rotor so they never rust. GM just thought it would be funny to align our pads in the middle of our rotors to make nice rust streaks.

When I did it, I just made a cardboard template of the rotor with the caliper cut out. This allowed me to spray the caliper while still on the car and get the "hat" of the rotor. I did that twice. This year though, if I get time, I'm gonna pull the caliper and do some better prepping.

 

Oh, and make sure you actually clean the caliper with some degreaser or something before spraying! I learned that lesson quick. :lol:

Tom, you should paint the braking surface for awesome stopping powa!

Yea, if you put some stickers on the rotors, it will increase your stopping powa!!!

I painted the hats on my rotors. I think I just used black rust-preventive enamel from Wal-mart.

Then I masked off most of the braking surface and painted the outer edge and the inner edge of the rotor with "zinc rich" Rustoleum Cold Galvanizing spray paint. It has held up really well over the last 3yrs.

 

I painted the rotors off the car, but painted the calipers on the car masking with a ton of newspaper and masking tape.

 

Not sure if this pic will work, but this is what it looks like
