soda blasting rotors

Postby washandy98664 » Sat Mar 09, 2013 7:15 pm



I was looking at blasting my rotors to get the glaze off of them and just clean them up.
Has anyone done this, and is it safe for the rotors?
I think I should be alright, but I have been wrong before. So just looking for a little advice.

It should certainly be safe enough for your rotors. My only concern would be whether the soda blasting is strong enough to break through the glaze. Certainly couldn't hurt it, of course.
What set up are you using?

don't do this because its dangerous but I actually glued 400 grit sandpaper to my old set brake pads and installed them, had the bike on the center stand and put in gear I let the wheel spin and I applied a little pressure to the brake slowly sanding it with ease, it took out the grooves pretty well, I did it later on after things got cool and put in some 1500 grit paper just to smooth things out..Why... because I can...That's why.. :lol: don't you go and do this because it's dangerous...and only I can do the dangerous.....don't need anyone getting hurt...Being stupid like me..

These are my front rotors and I am just using a light weight set up from HF, it works really good on most stuff I have tried it on, but this is by no means a heavy duty rig.

Well,,,, I wasn't going to tell you this but I did the front the same way and took it around the block several times and kept the brake on lightly on the front...Smoothed them rotors out.. But please don't be foolish like me.. I'm crazy which makes me different than most.. :D I still had back brakes and there's no traffic around here at 10pm in a quiet neighborhood... :shock:

I used a home made light duty rig and was also very pleased with the results, blew the carbon out of the combustions chambers and exhaust ports.....made them look like new.

Post some pics when you're done!

I figured that since I was taking my front end apart to do my fork seals and painting my calipers after I blasted them I might as well do the rotors as well.
This winter project I have started I starting to consume me...............

What Steve said was quite inviting to me,,I like the idea of making things like new again...It's a very time consuming thing working on these Wings, I have spent countless hours figuring things out about them.....I'm sure blasting them will clean them up fine... :D I had my Yamaha's turned once,,,250 bucks and the Beave wasn't happy for two rotors...But they were nice I gotta say..

Our buddy Beave IS right off the wall, but he does come up with interesting ways of solving a problem. thinking out side the box, sometimes WAY outside the box...................... 8-)

:lol: :lol: thanks Todd....I am ass backwards for sure...But My vacuum advance still works after three years or so [auto type canister mod.] ....My breakaway ramp is still the best tool I ever made.. My timing belt changing method is simply done, timing check is simple..tire changer stand is simple..I'm just a simple kinda guy... :lol: Oh and we can't forget the timing sight caps...Or my tent trailer, fishing pole holders..ha ha You cannot cure stupid or insane,,,I'm both.. :D Be sure to post photo's before and after you blast your rotors, I'd love to see the results...

Have never soda blasted rotors, but...have soda blasted carbs, so I don't think the soda will hurt the rotors. I need to ask, what is the glaze from? I use Scotchbrite and brake cleaner. That cleans the glaze and little rust on the outer rim pretty well. On a set from another brand of bike, back in my younger years, I used some navel jelly and Scotchbrite as the rotors had quit a bit of rust on the surface. It took the glaze off of them too. There is probably a bunch of ways to do it, but I like cheap if it get positive safe results.
