Brake caliper clean with dremel help!

[-S-]

Hi just got a dremel and kinda new to it. .. wanted to prep my caliper for paint ... anyway did i f**k up? Can anyone with a dremel teach me what to do? It is still smooth to the touch though and i was using the sanding band. Don't know what grade it is. .. was using the coarser 1 initially and i think it's making a lot of scratches. .. so used the less coarse 1 after that. ..

Thanks for any tips!

Also do i need to do sand it down till there's no more black ? All bare metal only?

You just need to hit with the hand and get it all smooth and most of the imperfections out.

There is no need to go to bare metal. It would take longer and with a dremel probably score it

Delicate things are always better by hand.

I initially did it by hand and omgwtf... too much cussing and too impatient. .. with a dremel it was a breeze and of course i think i might have scratched it a bit too... but thanks for the tips. I guess I'll start priming once i feel its ready. ..

Im prepping my calipers for painting aswell. I just dremelled the rough areas smooth as well as all the writing but the nissan. Now in the process of sanding them all down thoroughly with 180 grit.

Just take your time and sand them thoroughly until you have a smooth even surface. It will take a while but its the best way.

Just give it a sand and paint over it. doesn't need to be fully stripped. make sure surface is clean though. its just like painting a car, just give the paint something to key into, doesn't need to be bare metal.

Better off buying a pneumatic buff gun/gasket sander or a die grinder and wire wheel to do it. Can be far more delicate with both. I used my buff gun to remove casting marks off cam covers and then wire wheel all the crap off then give it a hand sand to prep. Don't even remember what i used on my brakes. Probably a scouring pad and some sandpaper. They are still fine 5 years (or more) later

Did u use the sanding band? For me i used these 2...


Flat 1 for hard to reach area. ..

thanks for the rest of the input but since i already bought the dremel might as well use it and see what other dremel users do

I just used a thick cutting disk but was very careful. Then just sanded with 180 grit. I have a bit more sanding to go but this took me about 10 mins.

i used the small wire wheel attachment to clean up the surface, no need to go to bare metal

Fooking hell...tell me you're joking ... cutting disc. I've got a lot to learn. But how about those angled spots?

Thanks . I guess a little black spot here and there won't hurt. I think 80% bare metal will suffice!

Just have to be careful with it. That being said i can just see a few dremel marks underneath the paint.

Just do the angles spots by hand.

As others have said no need to go to bare metal and its better to just do by hand. 30 mins of vigorous sanding is all it takes.
