Help! Front brake not working.

Just finished up installing my helibars and now the front brake does nothing. No tention at all. The instructions told me to slightly loosen the nut at the banjo fitting in order to rotate it forward. I did this, moved the brake master around, had to get the brake line on the other side of the throttle lines. Bolted everything back together and now nothing. I will admit a little brake fluid did leak from the banjo fitting but barely a drop.

What do I need to do?

 

If nothing is crimped, sounds like it's time to bleed the system. If you loosened the banjo, air crept in.

 

That's what I was afraid of.
Haven't done that one yet.
Can anyone tell me how or should I just take it to the shop?

 

I've never done it on a bike, but my guess would be a bleeder fitting on the caliper. If it does have this fitting, it takes two people. One person squeeze's the brake and holds while the other opens the fitting and lets the fluid out, then retighten the fitting while still holding in the brake handle. Then let go of the handle and repeat. The key would be steady pressure on the brake handle. You might have to do this several times, especially if the air is up by the bars. AGAIN, I've done this on cars, but the principle should remain the same.

 

this is intresting.. with linked brakes dose that mean back and front have to be bleed has any one done it?

 

You've got air stuck at the banjo bolt junction. The following procedure can be done with one person if you are dexterous.

The following procedure is commonly called "Burping the banjo".

Do this:
Prepare the banjo bolt for bleeding by cracking the banjo bolt to loosen it up and immediately tighten back with medium pressure so no more brake fluid comes out. You want to be able to easily loosen the banjo bolt - but not allow fluid to leak out when it is closed.

1. Pull the brake lever to about 1/2" from the grip.
2. Crack the banjo bolt to allow air/fluid out and immediately tighten again.
3. Release the brake lever.
4. Repeat steps 1-3 until the lever firms up. If the lever does not firm up, then you have air in the system at some junction point: calipers or junction block (if you have one)]

P.S. be sure to cover all surfaces as brake fluid makes a great paint remover.

 

Thank you so much Mason!
I'll be trying it tonight.

 

Thanks again Mason!
The burping technech work like a charm. I even did it to the clutch and firmed that up as well.
