Scooterotica

Hi
Got a scootrs disk brake for my lambretta and can't remember how it goes back together.
Problem I have is with the spindle when refitted.
When it is back together the end that is up against the metal bracket that holds the caliper will not let the nut sit flush with the plate.
The spindle has a ridged section that is ment to sit into the caliper bracket but it is slightly raised and the nut will not go to the bottom and meet the bracket.
Anyone got a diagram on how the parts slide onto the spindle in the right order.

The nut goes on the other side of the spindle to lock it all together.

Caliper bracket seems loose.
Pics on line show it fitted with nuts on both sides.
Just looked on beedspeed site and they do locking nuts with a reccess on them.
Just got new standard ones think this is the problem.
Scooter been in bits for 2 years so cannot find the old ones.

Right , if caliper plate has a rebate where axle sits and the axle has a shoulder as per GP ,no nut is used on that side. If the axle has no shoulder then a nut is used that has a step to sit in the caliper plate.

Yes the axle does have a shoulder but it sits just above the caliper bracket level when sitting in its reccess.
Most pics online show it with a nut on this side and its flush with caliper bracket.
Just rang beedspeed and they said there is a specific nut with a rebate in it.
So you get a nut on each side.

No nut needed, fit the hub to the forks and you will see that the shoulder will be fine. If you fit a nut the hub will not fit in the links or will put the wheel off centre. The hubs with a nut each side are the early or cheap versions that used a non shouldered axle. If the shoulder protrudes too much then a little fetteling may be in order but it usually stands slightly higher than the caliper plate.

The wheel is fitted and the shoulder is sticking out a small amount and that is pushing against the fork link leaving a small gap
Between the link and caliper bracket.
Brake pads are not in yet but the caliper and bracket seem to wobble about a lot.
If a nut was fitted wouldn't this stiffen it up

It needs a bit of float especially once the pads are fitted.

Axle fits in this sequence, slide axle through caliper mounting plate so that fixed shoulder sits in the recess in the caliper mounting plate, then slide on speedo housing cover, then slide on small spacing sleeve [it's about 10 /12 mm long] then slide the whole lot through the wheel hub and tighten the nut on the opposite side, there should be a top hat on that side. Once nut is tightened up there shouldn't be much, if any play in it.
