cleaning front brake disc bobbins / rivets?

[Val]

My front brake has a slight pulse at low speeds. The surface has no high spots (measured with a vernier while rotating the front wheel). As I've read that the disc is semi-floating, I thought I might be able to remedy the problem by cleaning the disc bobbins/rivets to allow the disc to float. At the moment everything is solid and I'm assuming the disc has a wobble.

I've seen videos on youtube of people cleaning the bobbins by putting a nut and bolt through the hole and using a socket to rotate them while giving a good application of brake cleaner. But mine don't have a hole in the middle?!

Do not beleive everything you see on the internet  :lol

As you have stated your disc is semi-floating and the bobbins does not have a gap and does not need cleaning by design.

The problem is somewhere else like the disc or the lines...

Have you tried oiling your pads, that should take care of any pulsing at low speeds, be sure to give a real good tug on the lever next time you want to stop  :eek :eek :eek

That was supposed to be a joke...but its not funny related to brakes, someone may take it seriously. Just to be clear do not do that
