Sorry to bother everyone with a bike question, but you all are the best and I figured you could help me.

I was greasing all the zircs (sp) on my KX250 and when I reached the back brake I connected the grease gun to it and filled it up. It was really hard to get it disconnected from the brake, but after I got it disconnected the rear brake stopped working. There is absolutely no pressure to the brake when I pump the brake lever. It worked great before I fiddled with it. Does anyone know what the problem could be?
Thanks a bunch for any and all help?

 

It seems as though I tried to grease the bleed valve on the rear brake. Hopefully I can get all that junk out of there and maybe it will work again. Thanks Anyway.

 

If the nipple was tight...nothing should have got in.
If you loosened it, and then squirted grease in, you got some work ahead.
grease and oil are the enemy of brake systems, if you get either mixed in the brake fluid, you need to flush and clean the whole system.

 

if you got grease or oil in the brake caliper you might have to rebuild it if it hurt the seals
good luck with it

 

Hopefully you didn't get any grease in the bleed off valve...If you didn't then just rebleed your break lines and you should be in good shape...If you did get some grease in there...............well..............better start tearing some stuff apart and start cleaning
