Well let me say I Hate Sram Level Brakes . when working they are great but my issue is always the Bleeding of them. they say how great and easy it is with the bleeding edge system. Sure that is nice but my issue is the levers . You can watch 100 you tube videos and they just screw in the lever port adapter and then open the bleed port on the caliper and just push the fluid from lever to caliper then caliper to lever and it goes so smooth. NEVER has that been the case for me. and yes i have the lever reach set at 75-80mm from the center of the bars. and i can push hard enough that the hose will blow off the port fitting and it will not push through to the caliper or back. its driven me so crazy that i opened up a lever and hooked a hose and syringe up to it to see if the reach adjust maybe needed to go a little more or less. and it doesn't move through the lever. it just doesn't make sense. ive had tons of sram/avid brakes and bleed them hundreds of times but these just wont work . I don't know what to say or do . I've rebuilt them from top to bottom and nothing changes . I cant believe i am the only person who has had this issue. the brakes are Sram Level TLM brakes. so any ideas or people who had the same issues . anything is appreciated

Are you bleeding the caliper and lever independently and using pressure from the syringe to the lever when releasing it from the bar? My levels bleed flawlessly

My nephew also has levels and I bleed them all the time I followed epic bleed solutions and haven’t had a issue

I'd call around to bicycle-specific shops in your area. To find the size I would try the manufacturer's website or contact the shop you purchased it at as they usually have more detailed info and could possibly have the size of the bearings. If you can't find that specific of info, find out what the model number on your hub is and then search to see if you can find further specs.

Most bearings will have the size molded into the seals. You may see something like 6802-2RS. The first part is the size code and the second is the seal type.

lol, Levels are so easy to bleed. I've literally never had a problem bleeding SRAM brakes. Bleeding Edge really does make it so damn easy.

Nah, Bleeding Edge is awesome. I honestly can't find a fault with it.

Some people just have a warm place in their hearts for hose and nipples.

Perhaps you could share your technique for those who seems to have less consistent success.

I do it the way SRAM tells you to. It never fails me. Nothing special about my bleed process.

Maguras are ok with the Jagwire mineral oil kit actually.

My issues are as follows:
1. The redesigned caliper requires a ball point when key to be used when tightening the caliper. A straight unit collides with the caliper and damages the paint.
2. The o ring on the syringe will wear out and can cause the caliper and the syringe to disconnect while bleeding the line resulting in DOT fluid every where.

I get that you're less prone to letting air in the system while disconnecting the syringe... But this isn't an issue for anybody who knows how to bleed a brake.
