<div dir="ltr">I noticed when I replaced the disc pads which requires pushing the pistons in which forces fluid back into the reservoir and since mine was just level with the wall that separates the F & R circuits I didn't need to drain any fluid out . Then I sucked out as much as the old fluid as I could , what I sucked out did have small flakes of rust which it didn't have before and the fluid was pretty dark even before this. Those rust flakes could have come from the calipers or metal lines to the master or the metal lines from the reservoir to the master. <div><br></div><div> I intend to rebuild the calipers . I think I can still use the old Anti rattle clips and the two pins per caliper they just have surface rust no pits . I am missing the 2 piston anti rotation tins on the right . Some places sell the entire kit including new caliper lock plates to spindle and the anti rotation parts . Can't the lock plates be reused ? I didn't consider bleeding with the calipers off through the rubber lines makes sense to do this . Since I'm changing fluid and most likely staying with DOT 3/4 could I just allow the fluid to drain out both the front lines and continue to pour in more new fluid to remove what crud my be in there rather than bleed as you suggested then try to see if gravity bleeding with some pumping at assist . I understand your point of capping the hoses and bleeding which will churn up any loose rust much better than just allowing it to drain. </div><div><br></div><div>William</div></div><div id="DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br>
