anyone tried vw passat/audi a6 calipers on the rear of their pre 85 cars?

Recommended Posts

I was looking around for alternatives(though my originals are ok for now) , and looks like pnm`s kit is based on vw passat/audi a6 etc calipers (00-05 ish i think), the s3 version they have looks machined, but the s2/s1 version looks like the exact same caliper and the pads match too..  would be good to know if they are one and the same..   i might look into it with my s3 as one of these calipers can be grabbed for less than £30 on the ebay.

ta, Mark

Not sure but PNM are probably unlikely to say where they source them from if they have gone to the trouble of finding,testing replacements etc :)

These are what you are discussing, yes they fit. 

Not an upgrade but a better version than the crummy girlings that have a rubbish hand brake. 

The cables need adapting though.

Maybe I'm missing something here but are we saying that a pair of Passat rear calipers are a direct replacement for the Lotus originals on an 84 TE and fit on the same mounts? If so I'm interested for my TE....🤔

... +1 for eeyoreish's question, sounds like these will bolt straight to anything pre '85. Is that right @top-plumber

I would be interested for clarification with this too @top-plumber @Mark Wainwright 

Can it be done as a straight swap, what adaption to handbrake cable, which model year Passat... 

Would appreciate the info. and any other relevant points. 

Cheers, Steve.

Wonder if the Passat later version calipers would fit, the ones with the electric handbrake, and would that retrofit be legal?

I popped what research i did online in my spreadsheet here.  This was detective work so would be good to get a full verification from @top-plumber  but i`m pretty sure its right.

Mine's all apart at the moment. I might go round to the mechanics next door and see if they have any of those cars in their 'will deal with that later' park. If they do; I'll do some testing and report back.

I notice on the pic posted by Wayne that the bleed nipples are at the bottom, which may mean you will need to bleed off the car (unless you can swap to the other side of the car.   George can you confirm distance between mounting centres of the originals and the rough overall dimentions, also including disstance of retracted piston to the opposing claw and finally the piston diameter?   (A number of the Ads on Ebay include such dimentions to allow comparison)

for ref heres the pnm engineering page which uses the passat calipers, i cant work out if any machining has been done on either for the s3/turbo or s1-2.2   but they look the same to me, incl location of the bleed nipple.

Do PNM offer the modified cables too or just advise on what the required modification is?

 They dont appear to supply new cables, which is probably good newas as it suggests the existing ones are not too difficult to adapt.   possibly need to alter the length of free cable, or do something to allow the existing able ferrules fit in the new caliper actuators.

this is an interesteing question.. someone should have a go! ;)

I dont see why it wouldn`t be legal..   i`d imagine the handbrake just has to work for an mot pass, regardless of how its installed... if they fit it`d actually be a nice upgrade.

I haven’t fitted these yet as the engine is still on the bench. Getting close to reinstalling but still a way to go. As soon as the gearbox and drive shafts are in I shall post pictures. Confidence is high.✌️

So far I have every reason to believe so. When I have installed them I will post all my findings

Ooh, I'm definitely interested in this and I may (eventually) even get to see them on Neil's car! Watching with interest...

So they bolt right up to the S2's caliper cradles then. That does it, I'm getting some.
