I have searched this question and found several posts pertaining to this problem, however with no real answers... I have a 1986 honda 250 (utility) with absolutely no front brakes. I have put on new shoes, wheel cylinders, a rebuild kit for the master cylinder, and blown out every brake line and it still isnt doing anything. I could bleed the brakes till i'm red in the face and still wouldnt have any pressure and it wont move the wheel cylinders at all. I was wondering if there was some special method of bleeding these brakes, cause i dont see how it could be anything else when all of it is pretty much new. Any help would be VERY appreciated cause i'm about to pull my hair out over of this...

Have you checked to see...with the drums off....if the wheel cylinders are actually moving? If so...have you adjusted the brake shoes?
Is brake fluid being pumped from the master cylinder when a line is disconnected?
I would start at the top(master cylinder)...the work my way down to the wheels.

 

With the drums off; the wheel cylinders will not move at all. I took the brake line off the back of the master cylinder and plugged the hole with my finger, then i pulled the lever and had what felt like really good pressure to me. Why is the pressure not getting to the wheel cylinders? Like i said i blew out all the brake lines; it doesnt make any sense why they're still not working... >[img]i/expressions/face-icon-small-sad.gif[/img]

 

its gotta be air in the lines somewhere...if u have a power bleeder thats the best way to do it. make sure there isnt a pinhole in the lines somewhere.

 

I have an 88' Honda 300 with the same problem. I've been told that the rubber brake lines break down over time and when pressure is applied to the lines, the lines themselves expand. I was told to switch to steel braided lines (cheaper than honda factory OEM lines) and that should fix my problem. Might be the same thing with yours. Just a thought!!
