I'm wondering if there is anyone out there who has done this before. I've replaced my stock brake lines and clutch with stainless and have been successful on that point. I've also got the back brakes working OK. However, I can't get the front brakes to work. All the lines have fluid but I can't get an pressure from the hand brake. I've checked and double checked; no leaks. Because the front and back are linked the front brakes work slightly when the back foot brake is applied but that aint gonna fly. Thankfully its winter so I've got a couple of months. I sure would appreciate any tips.

There is obviously some air still in the line. One of the best ways to make sure you get all the air out of the line without loosing a lot of the fluid is to first get a 1/8 id rubber hose about 16" long (like the one used on fuel lines for lawn mowers) and stab one end over the front caliper bleed off valve and the other end submerge in the upright bottle of brake fluid. Loosen the bleed off valve and begin pumping the brakes. This will ensure absoltuely no air re-enters the line and only fluid can be sucked back up into the line.

Remember the front /rear brakes have a spliter as where they are merged. I have found that doing the front first makes it much easier. You will need to bleed the banjo fitting at the rear brake master cylinder also, it will trap air there. Double check all fittings to make sure they are tight. On the front brake banjo, by the lever, you should bleed it also to make sure no air is traped there. If you have fluid at the caliper and pressure will not build up the chances are good there is a fitting not tight, sealed.

I do't know about all the others but

I replaced all the hydraulic fluid in my scoot and did it with the Mighty Mite vacumn pump. Cost about thirty five bucks but worth every dime.

Thanks for your suggestions. What I ended up doing was a bit of all suggestions. I waited a couple of days to see if the air in the lines would make it back up to the reservoir on the handlebars. I expected to see less fluid in there if it happened (the fliud would have replaced the air) but no luck and still no brakes. So I got myself a piece of clear hose and put it on the bleeders. I got a syringe from the local drug store, filled it up with brake fluid from the reservoir and then used it to slowly fill up the clear tubing. I cracked the bleeder open and using the syringe attached to the tubing slowwwwlyyyy pushed the fluid in to the bleeder valve. My daughter watched from up top and told me how much air was coming into the handlebar reservoir. There was lots of it. I could hear the bubbles coming through. I filled the syringe about 3 times from the reservoir and kept repeating it until there was no more air. I switched to the other side and repeated. Yahoo....brakes. I took the lid of the rear reservoir and bled the 2 front lowers and the back one the same way; looking for bubbles. It loooks like I have my brakes back. Thanks you all for your tips and tricks.
