Blown seal and no fr. brake

After blowing the fork seals while the bike was tied down I went for a ride and the oil leaked onto the disc and into the brake pads. I've replaced the pads, cleaned the disc and calliper with brake cleaner and installed new seals but the front brake is still not working properly. Anyone got any ideas because I'm all out?

Flush the brake fluid and thoroughly bleed the system. I have found when changing pads that if you push the caliper pucks in the lever can get spongy. If you need to push the pucks into the caliper body when changing the pads you should crack the bleeder and let a little fluid out when you push. I always put in new fluid when I change my pads. It's probably overkill, but it is just an easy way to keep track.

I just blew out both fork seals at the MX track on Saturday. I cased the same double 2 laps in a row, bottomed the fork hard both times. Came back to my pit to dial in some more compression and the whole front hub/brake assembly was covered with suspension fluid.

My wrists and back don't feel that great either :)

I have done the same thing and found out that sometimes just cleaning the disc with brake cleaner is not enough.

Take the disc off the hub and heat the metal untill it is almost red hot. Do this all the way around the disc on both sides.

This will cook all the oil out of the disc.

This has helped mine a bunch when I have gotten fork fluid on it.

Thanks for your advice guys. What is the best way to heat the disc? Should I invest in a heat gun or do i need to go even further. But a heat gun would be handy for removing all those white marks on the plastics.

Shane, I just use a propane torch.

Would a Self Cleaning Oven that gets to about 800-850 degrees work OK?

Mmmm, never tried that. Im not sure exactly what the temp is when the metal starts turning blue but if that is more simple for you and your girlfriend/wife dosent mind the smell of burning oil in the house.... :)
