I came here cuz Iv'e gotten some great advice in the past regarding my CRF450R and XR600R. Before you get mad and tell me to search, read this. I just need some more inputs,& tell me if I'm doing anything wrong. I have a 1980 Harley Wide Glide, and just swapped out brake rotors to a better aftermarket setup (GMA). The back brake was a snap, 30 minutes total from removal to bleeding. The front...I pump the front brake handle literally 100 times,(there is ZERO PRESSURE on it), crack the bleeder valve, and a tiny bit of fluid comes out. I have repeated this process and the same thing every time. Cap on/off/tight/loose. No change. I have a "one-man-bleeder" setup from Sears, it worked for the back. I tried a syringe injection for the front, I would crack the valve, and press hard, the fluid would not go in. The pressure popped the hose of the valve and got fluid all over the friggin place. I read in here that a dude just left the vavles open, and after a while fluid started bubbling out, then he just bled them normally. I have been working this for about 5 hours, and I'm about to go nuclear. Oh, the brakes DID work awesome BEFORE I went and jacked things up..thanks fellas... :applause:

I am not familiar with Harley's, but hopefully this might help. On some of the older KTMs the banjo bolt holes would not allow air to escape while bleeding the brakes. I took mine out and drilled another set of holes in them and it solved the problem. Look for high spots in the system that can trap air and check out your banjo bolts to make sure that they promote proper bleeding.

remove the brake caliper, and hold it high in the air, get the air bubble towards the top, then use your bleeder tool , ... whats really needed with them, is a power vacuum bleeder ... :applause:

I heard that raising the caliper might work elsewhere. Guess I'll try it. As for the power bleeder....

also tap the line with a screwdriver to move the trapped air clinging to the inside of the lines

I called GMA Brakes, the dude said that sometimes dual discs are a bugger, and often they have to get 2 guys with syringes to attack the system. And, sometimes, you can fill the master cylinder, crack the bleeder valve, and wait a few hours for gravity to do it for you. THen, all you do is bleed as normal...will see, hate to take it anywhere to pay $100 an hour....thanks for all the inputs.
