Scooterotica

hi....just putting my rebuild back together and just bolted the disc brake in the forks,theres a gap of 15mm one side of the tyre and 30mm the other
the only thing ive done is put a thinner nut on the inner of the kerbside spindle than the one supplied as it wouldnt go in the links at all with the wider nut
all brand new
any ideas?

is it the pepperpot disc? if so i got same problem...
if....i was to machine the guide for the pin wider on the speedo side i can get down to 6-7 mm, but it still a squeeze with the large nut on the kerbside. If i was to use a smaller nut it will be a larger gap, so i can't win unless someone got a better idea....

Is it definitely a scootRS disc brake? It's a common misconception to call anything Vietnamese as scootRS. ScootRS don't make a "Pepperpot" version, only Sterling [SPAQ] and Saigon Scooter Centre do those. The scootRS kit should have no nut or washer on the caliper side and a thick nut [about 8 mm ish] on the other side. If it doesn't go in like that then there's more than likely an isuue with your links or forks. The Sterling one is more likely to sit off centre because they use a thin nut on the caliper side and a normal nut on the other side. The Sterling caliper mounting plate is different from the scootRS one so it needs to have the thin nut, you can't remove it or the stub on the links won't seat properly. The cut out for the stub on the links on the scootRS caliper plate has an extra section recessed so that the area around the stub locates deeper thus not needing the thin nut. You can swap the plate on a Sterling brake for a svcootRS one to help centre it.
Also check the gap at the link bolt area and check the gaps at the top of the tyre in relation to the forks. Bent links and forks are the usually the culprit.

yes its a scootrs one
i managed just to put the fat nut back on at a push and it has certainly helped a lot,its not quite perfect but im going to live with it and just see how it feels on the road
thanx for the relplies

you should be looking at about 127 mm between the inside faces of the fork links the wider of the 2 nuts can also be fifferent ny as much as 1.5mm depending on country type (indian ,spanish ,or italian )
if you need to force the links out to get it right then you will putt pressure on them and this may stop them working correctly to much pressure one side makes the opposite dip when braking and leads to the wheel leaning over to one side .i know its a pain but it might be worth getting your forks checked as well
