This was right after i finished the motor build

 

thanks for the videos, ill try anything at this point, i really hate going to the dealer cause we dont have one in he town i live in.

 

Good luck, sweet ride by the way!!!! I really dig the front end.

 

I I had the same issue, I stopped using the bleeder screw and kept pumping the
Lever and mine started pumping the air through the top.
After a few pumps all was well, never had another issue, my brake is
Good as ever.

 

Sharp looking, thanks for posting the pic!

 

I had the same problem when I installed my ape hangers. I took the caliper off pushed the pistons back like I was going to install new pads. Put the caliper back on and open the bleeder let gravity take over. Then I bled the brakes

 

Ill def give that a try, i left it with a zip on over night and tapped away and still no luck.

 

DOT 5 will suspend micro bubbles and can be a bitch to get it all bled out. It took me several days to finally get my front brakes bled after rebuilding the master and caliper and replacing the brake line. I tried vacuum bleeding, reverse bleeding, pressure bleeding, and finally resorted to the old fashioned pump-hold-bleed. Nothing worked. I worked and worked at it and finally just got frustrated and walked away for a few days and when I came back, it bled out just fine using the old school method. I started by bleeding the master, connected the line and bled that out, then connected the caliper and bled that out.

After that adventure, I was not looking forward to rebuilding the rear but I bled the rear system using the pump-hold-bleed method and there were no problems at all...took all of about 1 hour from start to finish...including rebuilding the master and caliper, replacing the brake light switch, and flushing out the line.

 

Well after no luck on my part, i bit the bullet and rode to the dealership an hour away....lets just say $150 later its still no better. They said (and i saw) that the master had some scoring on the inside, i also saw this when i did the rebuild kit. But its very faint and i would have a hard time believing that it would cause this. After i mentioned that we tried a second Master before and had no luck. The shop guys had no clue, they worked on it for 3 hours and couldn't get it any better then i already had done. Since the master is the stock black, i decided to order a new chrome one and a new chrome clutch perch, so we will see when they come in later this week.

 

you can clean the bore with some high grit paper. if you think that is why. any reason your using dot 5 and not dot 4 as the manual calls for
