Hi, im having trouble bleeding the front brakes on my cbr 900 rrx, ive just fitted some braided lines and ive been trying to bleed them for the last 3 hours. I have followed the haynes manual method of pumping the lever five times holding whilst opening the bleed nipple then shutting again, ive got a clear hose attached going into a bottle of fluid and the top removed from the master cylinder. I am getting fluid through the lines but im not getting any pressure on the lever, questions ;
1) Am i doing anything wrong ?

2) Is there a way of bleeding the master cylinder ?

3) Or do i need to get off this pc and bleed some more ?

 

Easiest way to bleed brakes is fill the reservoir, leave the cap off, and open your bleeder nipples. Gravity will pull the fluid down to the calipers. Once you have a steady drip, close the nipples and proceed to bleed as normal.

 

ok thanks how long should i leave it like that for ?

 

It shouldn't take too long honestly. Make sure to keep an eye on the reservoir and keep it full. I'd say 20 minutes max. If it takes longer then there is a possible block in the line

 

If you get stuck again with you not being able to build up any pressure -

Remember, just go slow, and you'll get a good lever. That's half the reason they sell those jugs of fluid so big. They know you're going to waste half of it - even when doing a car or something.

 

Well I got there in the end had to crack open the top banjo bolt to bleed the reservoir worked a treat. Thanks for the help folks much appreciated.
