Cleaning Concours 1400 brake carrier bobbins

If your C14 brakes start to pulsate then it’s likely that your brake disk carrier bobbins have seized. Here’s how to easily and quickly give them a decent clean.

That's what I've done. Works so fine.

Thanks great video. What i have seen some do is use WD40 only when initially spinning the rivet. Then it is spun again withe brake fluid to remove it. I guess the logic is if the rivet is seised then it will free up easier and start spinning without causing any friction damage to it, the disc web, or the rotor. Although i agree entirely with any lubricants NOT being in contact with the rotors or pads, this may be a safer method, especially if this has not been performed yet for a number of miles/years. But, as you point out, care must be taken to have no lubricant (WD40 isn't however classed as a lubricant but exhibits some lubricating behaviour under certain circumstances. Really its a penetrating fluid) left on the rotors.

You do you, but I’ll avoid anything which provides a chance for residual lubricant to spin outwards onto the disks and pads. I’ll call any substance which modifies and reduces friction a lubricant even if that’s not specifically correct.

@@ChrisWiltshire Fair enough, thanks again for the video. Lots of people are unaware of this vital maintenance trick. Out of curiosity how many miles did it take to build up that amount of debris?

@@bailey-cj2plit was after one particular ride which was a SaddleSore in the wet and across dirt roads during that ride that my bobbins became stuffed. The bike has done just over 110.000 km now. I do approx 45,000km each year.
