Brake bleed after hose replacement.

Got the hoses fitted last night..

Looking at bleeding up the system. Started last night, but as expected, the brakes won't bleed. I don't have a mityvac or suitable syringe/pipe.

My thoughts (always Dangerous) as as follows.

1, Crack off banjo bolts to give the air somewhere to go.

2, Once both lines have a decent amount of fluid in them, nip up and bleed the calipers normally.

Sensible way to proceed.

Must buy Mityvac.

When I did mine It took a lot of pumping to even get the pads to move and then even more pumping to bleed the calipers. I started with the right caliper and bled that first then the left, which wasn't such a PITA for some reason. Then left the lever tied back overnight after a fluid top up and refitting the cap.
I did think at one time that it was never going to happen, but confidence grew when the pads were touching the disks.

Plan A worked out lovely.

Bars now raised to above yoke also. Makes quite a difference in a quick run round the block.

Was a little concerned about the hoses being too short, I went for +50mm maybe I should have went +60 just to be sure.

Tank off service and front pads next.

All good stuff.

If I may add to this thread, can I ask if any special measures need to be taken when bleeding the brakes on these bikes? I've never bled brakes on any kind of vehicle fitted with ABS, so unsure if I need to do anything different?

I always use a trusty old bit of rubber hose in to an old plastic tub, plus an attractive assistant on the lever (if I can find one willing!). I presume the engine should be running, but anything other than that?

Apologies for slightly de-railing your thread, but thought it might be handy for others searching for the same info.
