G'day all, quick recap - bought a wrecked '07 Riii, rebuilt and now riding regularly)
Took the Riii out on a back roads ride a week or two ago - lots of corners and sweeps - very nice - and my brake lever was pulsing like crazy, yep, definitely warped disks . . i had suspected, but . . not confirmed.
Fast forward to yesterday when I checked the bobbins on the front brake - they were SOLID - no a thousand of an inch movement!
- one interesting fact, they seem to be riveted on, not spring clip of bolt like every other bike I've had . . . odd.
So, today, I gave them a bath in brake cleaner, and using a stainless easy-out and lots more brake cleaner, I spun them very slowly while spraying the cleaner.
Once they loosened up, I kept going until the cleaner ran out 'clean'
Repeat for each bobbin on BOTH sides.
Took out for a test ride - AMAZING! these things have VERY good brakes! I never really felt confident with it - it always felt 'off' - not anymore!
So, quick tip - give you bobbins a clean and spin every oil change - this will fill in the 5 mins it takes for the oil to empty, AND leave you with a better feeling front end!
