Ok I’ve bled brakes on all sorts of bikes and cars before now without any trouble but I have just replaced the front reservoir and overhauled the caliper and cannot get the slightest amount of pressure at the lever. I pumped it slowly and got the usual little air bubbles. Now there are no more air bubbles, still no pressure. I have loosened both top and bottom banjos and seen a slight leak of fluid before retightening them and pumping again until air bubbles gone. Still no pressure at the lever.
Any ideas on this one anyone?.

I find bleeding brakes so relaxing. Here’s my tip:

Bleed screw tight
Reservoir cover off
Pull the lever in slowly
Watch the bubbles
Repeat
Watch the bubbles
Repeat
Keep going until you get a feeling of pressure

At this point, you can either start bleeding normally or put a cable tie on the lever and grip and leave the lever under pressure overnight, when you release it, lots of bubbles will float to the surface. Then bleed as normal...

Try releasing the master cylinder from the handle bars
&lowering it below the level of the calliper or
drawing through from the bleed nipple with a syringe

Thanks guys. I tried Nuttah’s way and sucked the fluid through from the bleed nipple.
That worked perfectly. :yup: :worthy:

You should be using 5.1, especially if running sintered pads, which you should be :idea:
