kroil or pb blaster , wd40 will not do anything , tiny pipe wrench works good if you have one .
how bloody tight are you putting them on ?

 

I've had good luck with a small socket. 1/4" drive hex head craftsman socket works like a charm!

 

I've had bleeder screws strip three different times. At the time, I tried smaller sockets, pb blaster, heat, vice grips, notching it-all that stuff. Even broke an easy-out in one trying to drill it out. Ended up taking it to a local machine shop where they welded a nut onto the bleeder and used that to back it out. Worked perfectly all three times after I tried everything else I could think of. After getting them out I replaced them with Speed Bleeders which are quite a bit harder to strip than the OEM ones. Also, I learned not to tighten the stupid things so much.

 

If all else fails....

 

 

WELL i finally got the bleeder out! PB blaster ....then i smacked a small socket on it and it came right out... now i am flushing the system, changing pads and putting in new speed bleeders! finally!! Thanks for the tips!

 

As you found out WD-40 is not a good penetrating oil. Others take note :-)

 

well put it all back together...but just as i thought my chrome aftermarket master is not working ...so i put the stock black one back on ..works fine speed bleeders definitely make life easier.!!!! i am pitting them on all my bikes next time i do brakes on them. i ordered a rebuild kit for the front master...hopefully that will work if not im gonna have to buy a harley chrome one ($$$$)...oh well at least i can ride it now....

 

Cool, glad it all worked out.
I bought a chrome aftermarket master cylinder once, not because of the bling, but because it was cheaper than a rebuild kit. Mine didn't work either, and when I took it apart it had metal shavings inside that had ripped up the o-rings......... QC in China is non-existent I assume. Ended up rebuilding my old one and all was well. Sometimes ya get whatcha pay for!

 

trust that will be the last time i do that! i mean really is it worth it to save a few bucks if your brakes FAIL!!! NO! some times when you try to save a few bucks it cost ya in the long run... i will give it a shot with the rebuild kit if that dont work im buying an HD one....
