Or whether to have a hidden master cylinder or not ?

It's the cutting /drilling through that rare headset that makes you think. I went through the bottom but you do have to cut a deeper slot than you first plan for because the headset top overlaps. Total time was about 75 mins. Worth it.

If you dont want to drill your headset rout the hose this way.

Life is easier with a goodridge or venhill braded hose instead of the thick rubber ones often supplied.

Always make the slot in the headset top, easier to replace than the bottom should you or a future owner want to go back to standard.
Love how Randall's made it look like it was his idea when it was Jason Frosts some years ago.

Definitely ditch the rubber hose, it's rubbish.

Cheers guys, when I bought her, she already had a you shaped bit cut out of the head set which I filled. Now I know what it was for - job done!
I also bought the Anti dive, are they as good as they claim?

It's a few years since I have run an external disc brake but I have run 2 ScootRS set ups in the past. On both occasions, I did not used the rubber hose supplied, I got the Venhill type replacements.
My own experience of both the external set ups I had was that they were a bit too fierce. What I mean is that they had little give, so much so that anything remotely like an emergency stop would immediately totally lock the front brake and cause it to skid.
I'm not set against external hydraulic set ups by any means but it has occurred to me that that are, IMO, a tad too fierce because:
1. The Master Cylinders are too big and pump too much brake fluid.
2. There is absolutely no "give" in the hose which there might be in a rubber hose.
Has anyone actually tried the rubber hose supplied?

You could probably also add
3. The disk is often too big for the size of the wheel.

I know of four fitted that could take the Pepsi challenge against any fully hydraulic confidently .

I've had a few scoot rs external disks found them very good but I wouldn't have anti dive as they seem to make the front wheel skip under heavy braking and you loose all feel at the front end when braking a good set of secondary dampers are a better bet

Seriously thinking of going back to a drum front end as my hydraulic brake is very fierce.Plus Ive really gone off the look of the reservoir on the headset too.
