Fitting the hydraulic disc brake

Fitting the hub was fairly self-explanatory, and the one problem I did have (front wheel not being central in the forks) I posted about previously, and I rectified it by straightening out some wear on one of the fork links. It is worth noting however that these hubs (mine's a SPAQ/Sterling jobby) don't require a nut between the link and the large plate on the right hand side. The hubs don't come with them, but at a recent parts fair I saw some of these hubs with nuts fitted - I guess the stall owner thought they were missing and fitted them!

Here's a pic of the assembly in place:



To connect it all I discarded the rather bulky rubber hose that came with the unit and bought a new slimmer Goodridge braided stainless steel one from http://www.busters-accessories.co.uk/. This is what I got:

Buildaline Adaptor Banjo 90deg 3/8 Jic Male 5.99 1 5.99
Buildaline Adaptor Banjo 45deg 3/8 Jic Male 5.99 1 5.99
S/B Buildaline Hose 1100mm Clear


The 90 degree banjo enabled me to avoid having any exposed hose at the top of the bike. I simply used a round file to create a hole in the top if the headset for the banjo and the small front brake wire to feed through. Here's the end result, a lot neater than any others I've seen:



And here's an internal shot, showing how it all worked out:


Here you can also just see a replacement white earth wire that I fitted from the headlight to the mounting point of the throttle guide. This provides a more reliable earth than the headlight rim as is standard. The loom comes in on the right on my bike, as I simply couldn't find the room on the left!

is your SPAQ front disc holding out ok,i`ve just bought one ,but have seen scootrs slagging them about the casting method used(sand casted rather than pressure casting)and reckons they`re dangerous

yeah I've seen those comments from scootrs. I think you need to delve a bit to understand why scootrs might be motivated to make such comments. My scoot is on the road now and it's all working well, especially the front brake! Need to update the blog but been a bit busy :)
