Help with brake bleeding

I just did a front master cylinder rebuild kit and installed a new braided steel line and cannot get all the air bubbles all out. This is why I did the master cylinder kit. The brakes still seem a little mushy. How much fluid does the system hold? Anyone have any ideas or tips? I understand the concept; pump the lever and hold, open the bleed screw and re tighten before releasing. The little bubbles just keep coming out.

Bleed the system the best way you can and dont worry about the feel. Make sure all the air is out using normal means.

Fix the feel this way. Depress the brake lever. Hold it in place overnight.

You can do it yourself, hire someone, or use a zip ty. Duct tape is good as well. Tape that lever to the grip.

The brake will be perfect. Dont know why this works so well, but it does. It even works on cars.

It will not work if you have huge air pockets in the system, but it is more like putting the finishing touches on the system.

I always pressure bleed the brake, attach a large syringe to the brake caliper and force the brake fluid up into the reservor. You need to hold the lever in and crack the bleed nipple the same way.

Or if you have an old set of bars take the reservor of and attach it to the old bars then put the old bars lower than the caliper and bleed as per normal.

The issue is trying to force the air down when it wants to rise.

another little tip is to tap the brake line with the handle of a screwdriver or the boxed end of a wrench, while squeezing the lever with the valve open.

Thanks for all the tips. I held the brake lever below the caliper and bleed some more. Seemed to do the trick. I have some tape wrapped around the lever and the bar and see how it feels tomorrow.

Interesting...keep us posted on how much it changes the feel.

A wonderful secret is to take your brake bleeding hose you put on the bleeder screw and zipty a loop into it. I'm no physics pro so I won't try to explain it. But I can tell you it works wonderfully.

      Hey guys I read an article saying that the 01 YZ125 has six gears. But other people are saying that it's 5. How many gears does it have? Just asking. Thanks.

      2006 YZ 250.. The manual calls for 10w30 (yamalube 4 stroke oil), can I use 10w50 (Motul semi sythetic 4 stroke oil) ??   I bought the bike, want to change the gear oil before I ride tomorrow but all I have at the moment is the Motul 10w50  semi synth.  Is that oil going to be too thick compared to the 10w30 or will it be fine..  Thanks

      Hey guys I just wanted to show off my bike and show it to the world lol  What is your opinion on it. God or bad, please be honest. I am open to all comments and suggestions. Any upgrades I should do to make it look better and/or faster?

      I bought a YZ250F yesterday and the previous owner said apparently it runs but they weren’t strong enough to kick it. I couldn’t kick while there so I took their word for it and bought it. I’ve been trying to get it to fire all day today, there are 2 chokes and I’m unsure if the air mixture is correct, so would be nice to know what I should do, it’s hard to adjust the air screw when the bike won’t even run. I noticed the spark is kinda low, I don’t know if it’s normally supposed to be like that or not. I can see a blue spark but it is very small and crappy, I’ve had thumpstars that generated stronger spark, I changed the plug it’s still the same, so maybe could be an electrical problem, the only ground connection I could find was for the ignition lead which I filed down to bare metal so I’m pretty sure that connection is good. Anything else I’m missing? It’s very hard to kick and I can feel the compression out of the exhaust so I don’t think compression is the issue.Just wanna know what I should do, haven’t owned a yz before so I could be not using the choke right or something. Thanks
