I am planning on changing my front dise on my 1989 td 90, but there are some bolts with diffrent shaped bolt heads holding the calliper in place any one know what they and the size??
They are twelve point bi-hex heads. Any multi point socket will fit (i.e. 12 points not 6) as long as it is the right size. From memory i think they are a 15 but im not certain, could be 13 or 17mm.
Ai, 13mm bi-hex. when you remove the disk from the hub, put the wheel studs back in the wheel on the floor, you will get more leverage on the bolts holding the disk then... that is if you dont have a vice, which i dont.
