600 monster rear brake
 

will it hell as like bleed any offers

Check the bleed nipples are up tight as they are dreadful for pulling air through if not sealed properly!

Is it an underslung caliper, i.e at the 6 O'clock position on the disc?

If so you need to remove the caliper to position the bleed nipple at the top.

Thanks ghost i will try that i just cannot get any fluid through the master cylinder im wondering if it that what is duff
