J/C, why are you cleaning the rotors? They dont get dirty per say unless there is some gunk build up in your pad assembly in which case you may want to disassemble that whole thing and clean like Scott said. If you are having some shudder or it pulls to one side under braking though, they may be warped and need to be cut by a shop. Is there scarring on the face? It is normal for rotors to look beat up, they do go through hell lol.
How did you make sure the paint didnt get in the contact areas? Also, how long did the process take you? When could you dive next, and what did you tape off?
So, the Rotors, and part of the calipers are done, and they look soo great. That rust killed the look. I am in the process of making a stencil for painting the edge of the calipers. Any ideas on how to do so? Can I Polish the rotors in any way?
I just replaced all 4 of my rotors... use masking tape on the surface so it doesnt get onto the contact area, then use some hi temp caliper paint. I picked some black VHT up for like 6 bucks and did 2 coats on 4 rotors, front and back, and the 2 front brackets the hold the calipers in place.
Measure the rotor hat, scribe a circle of that diameter onto a thin chipboard, and then cut out the circle. Lay it over the braking surface, and you don't need to mask anything. A bit of overspray will come off with the application of the first braking.
To pull the rotors, you need to unbolt the calipers. Simple enough, and just be sure to hang the caliper on a suspension part and don't let it pull on the brake line.
I did my rotors calipers this summer. Like other said, there is just some bolts to remove. Its easy.
I sandblasted everything (rotors and calipers), did two primer coating and then two paint coating. I did not used high temperature paint.... 3 months so far and the paint is just like when I sprayed it. I don't know how it will handle the winter... they put lots of salt here !
When you remove the 2 bolts off of the caliper, do you have to compress the pads to pull it off because I removed the two bolts and it did not come off.
For the front calipers, there are 4 bolts (two bolts for the "pad holder" and two other bolts "pad holder holder !?"). You have to remove the last ones (pad holder holder), the bigger ones, and the whole assembly will come out. The pads are tight but you should have no problems for removing them. They are much harder to replace them on the rotor because they are very tight but I did my fronts and my rear at least two times each with no problems (only using my hands).
getting them back on isnt hard if you arent replacing the pads. The only time you need to compress the pads is when you put in new rotors/pads to squeeze the piston back out.
