Default Pulsating front Brake

Something I started to notice recently, and Im not exactly sure what it is.

When Im braking VERY lightly, or when Im almost coming to a stop, sometimes I'll have a bit of front brake on, I can feel it pulsating, it seems ot have got worse of the last couple of weeks.

IT DOES NOT happen under hard braking, only whne slight pressure is applied to the front brake and Im going relavtily slow speeds. Any ideas? It feels sort of unsettling

I'm interested also in an answer. I think my feeling is almost like I can feel the drilled holes in the rotors sometimes while braking. It could be a pulsating but thats what it feels like. It happens only sometimes and she still is braking fine so it does not worry me at all.

Check the bobbins that hold the floating discs, and make sure that they are indeed "floating" and not full of brake dust! You should be able to turn them (allowing the disc to float) If they are tight, Give them a good spray with brake cleaner tighten a nut and bolt through the hole in the centre of the bobbin and turn this bolt with a wrench, this in turn will free the bobbin allowing the disc to float and should remove the slight judder!!

Default hey dave

I have a similar problem i think Ok so when i kick my front tire i notice a rattle noise through further kicking of the front tire sounds like the rattle noise is being made from the rotor bouncing off the brake pad general area.

has anybody have had this problem or noise before I kicked my friends front tire and it didnt make a peep of a sound... but when you kick mine it does a super fast light rattle noise...what could be lose any help would be great
