Title: S2R1k Rear brake disc, floating?
Post by: billg69gmc on May 02, 2010, 05:06:37 PM
Just because I bought a SF, does not mean I am not a dedicated Monster fan! I still ride the S2R more than the SF... Almost 18k on it now after two years.... So I ran into a problem with my rear caliper, it had a sticky piston and it ate up the brake pad and then started munching on the rear rotor.

I replaced the caliper with a like caliper from a 749. Replaced the pads. Replaced the rotor with an EBC. After initial run in, I had gotten brake squeal, so I decided to pull it apart and clean the rotor and sand the pads in case they were glazed.

When I got it apart, the rear rotor seemed to  have play in it. I know I torqued the freak out of the rotor bolts with red loctite and the bolts did not back out.

Question is: Should the rear rotor have any play where it floats on the rotor bolts. I know the bolts are threaded to leave a section about the thickness of the rotor, but I was unsure if something was going on. There is a minute amount of play side to side, but spinning wise, it is definitely floating on the bolts and not snug. I just want to make sure it is ok and not the fact that I installed the EBC rotor... I just don't recall the stock rotor floating.

Thanks!

That doesn't sound right.  The stock rotor shouldn't move.

Float on the bolts?  No.  If it is a floater it will have buttons.

Made some custom fit washers (had to drill out and shave the outer circumference) to fit the EBC rear rotor. All is good and thanks for the feedback.

Maybe there was just a slight difference in thickness between stock and the EBC. Also, if you aren't riding your streetfighter that often, do you mind if I borrow it?  [evil]
