mystery brake judder
Hi all , Iv recently been having problems with the front end of my bike. She is a 2007 CBR 600 RR which i have owned from new and just hit 18000 miles on.
My Problem is Front brake judder. It started out With a really violent judder at all speeds and amount of brake which at low speeds would pulsate the brake lever so it was obviously a warped disc.
I Decided to change the hole system and bought armstrong wavey rotors , braided lines and EBC pads, Along with a strip down and clean of the brake calipers, i jumped on the bike for a test ride to find that the judder had reduced a lot but was still there if i lightly held the lever on, If i slamm on hard it brakes smoothly.
I had the head bearing checked and the bottom had gone so i had new steering bearings fitted at the dealers only to find that the judder is still there.I took it back to the dealer and found out that the bearings had seated and needed to be adjusted, so they did, it improved it but it is still there.
The only thing i can think of that i have not replaced is the wheel bearing.
with the wheel of the ground it does not feel loose however there is a slight click in it and if i hold the front brake with the bike on the floor and rock the bike forward and back there is a clunking that feels like the wheel bearing is loose.
Could it be the wheel bearing clunking even thou when lifted i cant make it clunk with my hands?
Is there anything else that im missing that could make the front end judder when lightly pressing the lever
LEAVE LATER RIDE FASTER
