Just been down to the Ratcave again and the spacer is there.

I may be WAY off the mark here, but after looking at the fiche pictures and yours, are you sure you havent swapped A for B as the inboard 'spacer' looks thicker than the outboard.
They have them listed as bearings, swapping these round MAY give you the correct clearances as required, if I am wrong then ce'la vie.

thats how it got like that

 

[chunkolini]

Metalspanner did think of that one, the outboard spacer is a part of the bracket.
The inner one is a spacer that tucks into the dust seal.
What is bugging me now is that the bracket does not need to bend or move.
The caliper does all the moving, the pistons slide, the caliper slides.
Aaaaargh!

When it went back to the shop did they fit a replacement swing arm as the old one had a "hole" in it? Have they fitted an ABS model arm and are there any differences in models?

 

[chunkolini]

Doubt it, that was in May and I have put 4000 miles on it with no worries sice then.
Like the inverted commas.
Been thinkng over this again, I am sure it must be something simple and stupid, probably me.
The caliper should slide on the pin, instead it is trying to bend the mount, I will whip the caliper off again and have a look upo the hole it is meant to slide on.

I've just had another look at your picture at the beginning and you've got something wrong where the calliper bolts to the bracket. There is a gap between the rubber and the bracket and it should sit up to it so your slider is on full travel and is trying to pull the bracket instead of the outer pad. Take the bolts out and fit the face of the calliper flush to the bracket and see how it looks.

That was taken 'in the heat of the moment' I was not a happy bunny and had not tightened and straightened everything up properly.

I took this just now, after riding it for a couple of days to work. I popped the pads out as well and they look fine, and are contacting the disc square contact all over, not rubbing at one end or the other.
There is no friction between pads and disc, spin the wheel by hand and it runs perfectly, disc is cold if I get off the bike without using the brake, so no rubbing going on.

working OK now?

 

[tigler]

Shouldn't there be dust seals on the pistons ?

 

[chunkolini]

Dust seals and oil seals are inside the caliper.
I remember stripping a bike brake caliper years back and thinking 'how do they expect this to work for more than 5 minutes' the seals are a pair of elastic bands or something like that, maybe fancy pants plastic but there is nowt to them.

Seems to be working Ok now, being monitored, but seems happy.

I was referring to external dust seals rather than the hydraulic piston seals. All road cars have them and most bikes do to.

 

[chunkolini]

All that listed is two internal seals.

Got to go.

Many bikes are just as chunkolini says and just have rubber rings leaving the piston exposed to all the road crap. Same as landrover defenders. Crap design but we the customers put up and pay up.

 

[tigler]

Shocking ! Even with stainless pistons I wouldn't be happy about that ! Even the calipers on the Spanish made Sanglas I just bought have external dust seals for the pistons, and all the disc braked bikes I've had in the past did too, apart from a Ducati 996 SPS, but that had race spec calipers which don't have them as standard.
On a sliding caliper piston it's worse because the pistons become more exposed. They must expect them to be serviced at more frequent intervals.

Right, I finally got round to taking a pic of the rear brake on my ST13, the pads may look like wafer biscuits but they've only done 1000 miles or so - as I said, they don't have much meat to start with. I couldn't get a better pic as the tyre was in the way.
Quite a lot of piston showing...

 

[chunkolini]

Wedgie, what kind of an effort is that, cant even be bothered to remove the tyre.
I am hurt.
Not really, that looks just like mine, I think I may be sorted, but still confused.
Tigler how is the Sanglarse?

Waiting for parts from a new found friend in Spain !! Have asked him to find a complete set of gearbox internals so I can just replace the thing wholesale. Then I need a pair of shocks and to do some minor fettling and it's all good. Should be ready for next spring.
The seller is unfortunately a lost cause but I'm engineering my own karma
