TOPIC: Why do rear rotor bolts rust? Forum Tools Post New Topic Show latest posts Rules

#1017869 Lifeguard (User) Alright everybody out of the pool. Platinum Boarder Posts: 1108 Why do rear rotor bolts rust? 7 Months, 1 Week ago   Installing some used rotor bolts on the bike and can't figure out why they rust. My other bike (still can't get used to saying that) has the same issue. Those I polished when I polished the rear rotor and they are starting to rust too now. I keep the bikes indoors. Aren't they stainless lime the fronts, which don't seem to have this issue. Anyone have an idea?   Logged     The usefulness of a cup is in its emptiness-Bruce Lee   The administrator has disabled public write access. #1017879 ultrastar (Moderator) We Call Her Big Red (Secretariat) 110 Big Bore Moderator Posts: 9536 Re:Why do rear rotor bolts rust? 7 Months, 1 Week ago   Lifeguard read this https://www.polymersolutions.com/blog/why-does-stainless-steel-rust/   Logged     My Rides   The administrator has disabled public write access. #1017880 ctkog (User) Expert Boarder Posts: 523 Re:Why do rear rotor bolts rust? 7 Months, 1 Week ago   The rear rotor bolts aren't stainless nor chrome plated. Hence rust unlike the fronts. If you take a strong magnet to the front and rear you can feel quite a difference. Why yami didn't use the same on the rear who knows, maybe because the front goes through the puddles first?   Logged     Last Edit: 2017/07/23 20:08 By ctkog.   ---------- NOTHING STRAIGHTENS MY HEAD OUT BETTER THAN AN ENTIRELY CROOKED ROAD-----------   The administrator has disabled public write access. #1017883 ultrastar (Moderator) We Call Her Big Red (Secretariat) 110 Big Bore Moderator Posts: 9536 Re:Why do rear rotor bolts rust? 7 Months, 1 Week ago   Both bolts in the front and rear or stainless I polished mine and there's no other material that will polish like stainless except for aluminum and they're definitely not aluminum. Granite the part numbers are different that could be because of the length   Logged     My Rides   The administrator has disabled public write access. #1017884 Lifeguard (User) Alright everybody out of the pool. Platinum Boarder Posts: 1108 Re:Why do rear rotor bolts rust? 7 Months, 1 Week ago   So why then do they rust up so easily and the fronts not? I was thinking that I would just shoot some clear coat on them after polishing the rust off. Maybe that will help some.   Logged     The usefulness of a cup is in its emptiness-Bruce Lee   The administrator has disabled public write access. #1017886 ultrastar (Moderator) We Call Her Big Red (Secretariat) 110 Big Bore Moderator Posts: 9536 Re:Why do rear rotor bolts rust? 7 Months, 1 Week ago   I can't answer that but I know I had signs of rust on my oil lines bolts others as well   Logged     My Rides   The administrator has disabled public write access. #1017887 ctkog (User) Expert Boarder Posts: 523 Re:Why do rear rotor bolts rust? 7 Months, 1 Week ago   Maybe the rears are martensitic stainless. does martensitic rust?   Logged     Last Edit: 2017/07/23 22:20 By ctkog.   ---------- NOTHING STRAIGHTENS MY HEAD OUT BETTER THAN AN ENTIRELY CROOKED ROAD-----------   The administrator has disabled public write access. #1017917 jd750ace (User) Front toward enemy Platinum Boarder Posts: 18763 Re:Why do rear rotor bolts rust? 7 Months, 1 Week ago   Ctkog wrote: Maybe the rears are martensitic stainless. does martensitic rust?

Doesn't seem to matter, they rust. It has to be from washing it and living somewhat close to some water as mine sits inside 100% except when I'm traveling. And I avoid rain.   Logged     The administrator has disabled public write access. #1017932 RoadstarTerry (User) Senior Boarder Posts: 363 Re:Why do rear rotor bolts rust? 7 Months, 1 Week ago   Here's my stab at this topic. Stainless rust is accelerated by high heat and fastened to dissimilar metals. I believe the rotor bolts have a coating on the threads when new. Just my 2 cents.   Logged     Pat Tillman American Legion Post 117 Service Officer American Legion Riders Patriot Guard Riders Patriot Guard Rider   The administrator has disabled public write access.
