bleeding brakes

After my bike was laying on its side coming back from Sylvan island the brakes are not as strong. Have to pull levers all the way. I know storing bikes upside down will cause issues, but also on its side?

Do you guys pull the brakes off to bleed them or just on the bike?

I have formula brakes. Looks like I need to get the bleeder kit.

I have never bled mine yet. My Flux needs it, as the front brake doesn't work any more, but my Look is good. It's kind of a pain, and Scott made me do his because he's a train wreck, but not that bad to get back to stock feel. The bleed kit makes it a ton easier.

In order to bleed your brakes. All you do is connect a rubber hose to the bleeder and then the other side to a water bottle to catch the brake fluid. When it comes to bleeding, you have 2 options:

1) completely drain the brake fluid > replace the brake fluid > VACUUM all the air out of your lines or until you feel the pressure build up in your brake lines.

2) I RATHER DO THIS, BTW - drain the brake fluid, as your reservoir starts to empty out, fill it up with clean fluid. The key is to avoid letting the reservoir completely drain out and get air in the lines. So if you keep pouring clean brake fluid over the old one until your the bleeders starts to spit out the clean fluid. You can then close it out because the fluid is clean and there is no remaining old fluid in those lines.

I went ahead and did both actually. Lol. First time I did option 1 on accident. I let the reservoir drain out (that was for back brakes). For the front I keep filling up the reservoir until clean fluid came out, then repeat on other side (front | 2 bleeders). As far as the back brake, it was a BIOTCH! We couldn't get pressure in it for 3 hours. Then figured out we have to vacuum pump the air out of the lines because we let the reservoir completely drain out.

Another thing, pump the brakes as it drain to force fluid out of the lines and into the water bottle or brake fluid catcher

Here are pics from when I did mine:

Here is a pic of the valve to release the fluid ("bleeder" as I've been calling it)

Best of luck!
