Some sort of sliding bracket??

 

sorry to go off topic martin but someone off here said you might still have bruces old escort cosworth shell for sale? or do you know of any?
Thanks

Back on topic

 

My best guess..

Looking at the photos, you can see that there is only the width of a pad on the near side of the caliper, and extended travel on the 'pot' side of the caliper. They look like they are radial mounted, which is wierd, but they must be floating.

At a guess, they work by effectively pulling the far side pad onto one side of the disc, whilst the near side is directly applied to the disc.

I can only presume that this is to improve unsprung weight????

always wondered myself would be good to know.
its usually msport selling them.maybe worth asking them?
usually pretty cheap aswell

 

martin,the only answer to this question is THEY DONT WORK,hence M-sport didnt use them on the super 1600,s!!and they have sold shed loads off cheap on ebay to get rid!
it was a slidding bracket but they realized it just doesnt work so scrapped the idea.

 

Cool, thanks for that But how the hell did they get a 909 number if they don't work? Was it an Alcon design failure or Fords?

 

MD COS has brought a set of these for his es cos build

 

quality paper weights

 

Wonder how badly "they dont work" if you get me?

As im sure they were tested to high heaven beforehand?

Look awesome, would be interesting to test.

 

tested to high heaven my arse!!!

 

bizzare idea, were they limited by rules or somthing?

 

So they just slung a totally untested and brand new idea together n hoped itd work?!

 

I was told that they were specifically designed and used on super 1600 fiesta's, so did they crash with no brakes??

 

when developing a rally car not every "bright idea" works,when placing an order for parts etc its not always controlled and checked either!

 

buy some and try them then martin.

ring neil at M-sport,iam sure he will still have a few there he would happily get rid of,sorry i mean sell you.

 

and while your at it if you have a push bike you could buy a few hundred sets of the matching two pot rears,thats if you can find a disc small enough and thin enough to match them.

 

Might buy a set to play with, as far as I can see as long as some sort of sliding bracket is made then they would work fine ... Just like modern single pots...

 

martin did you see my post above mate?

 

yes but it's off topic!! I have the shell pm or call me..

 

if theyre a 9.6mm thick 280-300 mm diameter disc then i might take a few pairs

 

having seen the pictures i understand who they work

you buy 2 sets amd use the bits without the holes to make one set of 6 pots

 

They are Monoblock design

 

MARTIN,are you serious there?

if so thats rather worrying,as any modern or not modern sliding caliper is not radial mount so pushes and pulls against itself,these are radial mounted,think about it eh!!

 

smaller than that tony.

 

I understand exactly what you are saying but whether it radial or lug it still needs a bracket ... which could be sliding .... Just thought they looked nice and with a little work could be a cheapo brake kit

 

Wasn't this the reason a car M Sport were testing went flying off and crashed?

 

oh yeah

i'm sure someone can weld a bit of ali over the holes, or soemone might try

 

Would it be a problem for road cars that they don't have any dust seals etc? Or is this something that could be developed ?

 

a radial mount on a slider trys to twist the caliper this drastically reducing its effectiveness,this was found out on testing these calipers,very unreliable and very stupid to put on a competition car that really does need to stop!
what next?square wheels or cages welded in backwards?

 

I have used calipers without dust seals on the road for years without issues...

 

Actually I did think about the cage thing you mention

 

Interesting...

Surely they cvan't be *THAT* dangerous? Or they'd destroy them not flog em on? Dunno though, I aint the expert..

 

Tim is just pissed off because he wants them all for himself

 

go on,put the pictures up,i havnt seen them for ages and it still amuses me!

 

I fancy a set

 

i could have had them all years ago if i wanted martin.

friends in very high places remember.

 

The calipers work in exactly the same way as 99% of road car calipers do.
On the Super 1600 Fiesta the slider in an integral part of the aluminium front upright and would be hard to fit to any other hub. However a similar system to work on any chosen car could be designed fairly easily.
They worked well but it became apparent that they were just not ideal for rallying where everything gets covered in shit unfortunately including the sliders. So for a track day car they would be more than adequate.
The calipers are from Boreham Ford Motorsport, where the car was designed and MSport then later inherited them.
They were superseded by Focus WRC calipers.

Just out of interestCosworth Rallyesport do you know anyone at MSport?

 

Same as an astra GTE single pot setup, sliding bracket.

 

u could email them and ask for the info they got on them brakes

Had my KAD 4-pots for 2 years, they dont come with dust seals, never had any troubles
