Removing all 4 callipers: plug lines?
Over the next couple of weeks my next project will be installing new rotors, pads and sensors all around. I thought that while doing this it would be a good time to also completely remove the callipers to clean with a rotary tool and paint them (satin black), do a CDV delete and finally a brake fluid flush.
I've changed a ton of rotors and pads before on different cars but I've never done a brake fluid flush nor have I ever removed callipers from the brake lines. So I what I want to know is what is the best way to go about this project/what order should I go in? Further when I take the callipers off from the brake lines should I plug the brake lines with something like a golf tees or clamps? I ask because I've heard that it was bad to let all of the brake fluid out. My current plan: 1)remove old pads, rotors, sensors 2)remove all 4 callipers 3)plug or clamp brake lines? 4)clean + paint callipers 5)unplug/unclamp lines one at a time and reinstall newly painted callipers 6)install new brakes 7)perform CDV delete 8)do a brake / clutch fluid flush A)Does that process seem sound? and if so I still don't know what to plug or clamp the lines with B)Should I invest in a brake bleeder kit like this one? |

You might want to figure out who you know that has a sand blaster. That's the only way to 100% clean the calipers and holders. I'd use a high temp etching, primer first & then use 800 grit sand paper, on the primed surface. Then use G2 epoxy paint. Last, I'd seal the paint with 3 coats of high temp clear coat. |

Erect a jackstand against the seat and brake pedal to hold the pedal down. That will close off the master cylinder feed port and you will lose very little fluid. You will have to release the pressure at the calipers by opening and catching the fluid from any front and rear caliper.
