When I'm riding it hard into and out of corners and on the brakes hard into the corners to try and keep up with all the revs. Sometimes my brake gets spongy and then I pull it and nothing is there. I've almost hit the woods really hard because of this.
I've changed the fluid and bled the system. Also put in new pads.
Do you think it is my caliper or the master cylinder? :2strokes:
 
Did you check all your lines where they bolt together for leaks.When you changed the pads were they totally worn out, so far that they wore out the pistons? if so they are not pushing straight and it causes the floating brake to work improperly. My viper did this but I had the pistons worn out along with my disc!
 
Check up by the brake lever the 14mm nut and 12mm nut sometimes come loose and let air in the system. My viper put me into the sticks before because of this. Went for the brake and pulled right to the handlebar and nothing but trees!
 
Have checked everything on the line, caliper and master cylinder and have never got any air out of the system. Somebody told me it could be the caliper because it only does it when its hot.
 
I had a similar problem with my 01 raptor 660. I changed the line out for a braided stainless line and it fixed the problem. The rubber line would flex/swell causing a poor lever feel. Also these master cylinders are tricky to bleed, you sometimes have to use a mityvac or push the fluid the oposite way. Like bleeding a clutch slave cylinder in a car.
