Hi all, a new member which has a problem. Could someone advise me on the set up of the front disc? I had a bolt snap off and drilled it out and removed the remaining bolts to find only 2 bolts had what i would call top hat bushes, should there be 4 and should the brake disc move like a fully floating disc or be stiff for this model? any pics or feedback would be great, many thanks lee
