I'm about to attempt my first solo brake pad change on my 2018 URJ-200. I've looked at/felt the rotors and they aren't scored. I wasn't planning on changing the brake fluid (it's been 30k miles since it was changed). Are there any concerns I need to know of regarding the compressions of the brake pistons? I was planning on opening the brake fluid reservoir to let the excess fluid back up into it. However, the resi is at the MAX line now. Will compressing the pistons cause any damage to the master brake cylinder? Or should I plan to replace the fluid as well? Is there a tool I should use for that? I've seen the Jafffa Adventures YouTube video on pad replacement, and it looks easy enough. I've also seen the video on using TechStream to flush. Should I do this as part of my maintenance? I was planning on upgrading to DOT4 brake fluid if I had to do it. Thanks for the assist!
