I want to extend my thanks to my fellow K75 owners who have troubleshooted the nagging pulsation in the front brakes on this bike. I've really enjoyed the bike except the stopping was really getting on my nerves - bounce, bounce, bounce, bounce.
Not wanting to invest in the rotors, I first changed front wheel bearings, bought new Carbone Lorraine pads from Mike at Beemer Boneyard and removed and scribbed my rotors with a 3M pad and paint thinner - then cleaned with brake cleaners. To my naked eye, the only thing I could see was some minor pitting. I took the rotors to O'Reilly Auto and they spec'd them with a micrometer and everything looked not just good but very good. Mine only has 33K miles on it.
After my time to R&R the front wheel, install new pads and R&R the rotors, I imagined I'd fixed the problem but soon it started the pulsing again - one member suggested I go fast and hit the brakes hard a bunch of times - maybe it worked for him but not for me.
Finally, I thought long and hard on do I really want to keep this bike and throw another 4 clams into a non abs braking system? Then I thought would I want to sell a bike to someone with bad brakes? So, I elected to buy the rotors. I must admit I was very skeptical. I conferred with someone in the know about BMW rotors and he said the OEM's have had their share of problems.
Besides, gang - we're talking a BMW machine - synonymous with precision and quality and advanced engineering, right? Why would I settle for a bike that has poor stopping characteristics?
So the happy conclusion to my story is the EBC rotors are terrific! My bike stops smoothly as she should and I'm getting a LOT more pleasure riding her.
Special thanks to Don E. who really took a long and expensive journey to get to the bottom of this issue. It just took me a little convincing to get it right.
Thanks so much!
