Shimano R600 Brake Levers...Buzzing/Rattling...

The Genesis Skyline is fitted with the R600 Ultegra levers and although not retro some on here may well be using them, hence the short write up.
Reading reviews there seems to be a bit of a problem with them rattling and mine were no different.
I decided to investigate further as the constant rattle/buzzing from them was starting to annoy me so much so that I had thought of changing them over for something out of my parts bin.

If you pull the lever and look inside you will see a small U shaped piece of plastic. From what I've read (and I don't know if there is any truth in this) but the only reason for this U shaped piece of plastic is to aid the robotic assembly of the levers. However my take on it is that it's there to ensure when you are tightening up the levers to the bars you don't inadvertently dislodge the return spring and also to aid with placing the Allen key in the correct location as this small piece seems to be a guide.

I decided to remove the U shaped plastic part using some long nose pliers and yesterday took the bike out for a spin, the brakes work fine and the best part is the levers are completely silent, so the parts are now permanently removed and destined for the parts bin forever

I know it's a bit of thread resurrection, but thanks for posting this info, I have recently bought these levers and am less than impressed with the rattle, now I know what to do!. Cheers Matt
