Vacuum pipe blocked off...

Recommended Posts

haha, ...maybe! :)

 

Swine! I wanted it but he sold it to you instead...still haven't forgiven him for that :x Only joking, enjoy :lol:

 

Anyway, how bizarre, I never knew LHD VRs had no brake servo! You learn something new every day 8)

..sorry Kev! ...fortunately for me I was the first to contact him about splitting it once I knew he was selling the VR, and being the honourable chap that Asim is I got first refusal! Cheers again mate!!

 

No, me neither and nor would it seem VW, as I popped into my local one this morning to order the necessary gaskets for fitting the VSR, and when I mentioned this to them and they looked at me like I was speaking a foreign language (which I was to them but you get my point!)

 

Anyways, thanks for the input guys - I can now rest assured that my brakes are 100% good. Now then, on to all that lovely torque below 4000...

...that torque plot you sent of your before and after runs is amazing mate. I might frame that and stick it on the wall! 8)

 

Like you say, should've been standard kit...

OK, the Corrado model range for all countries has the option of 5 braking systems broken down into 3 groups.

 

1) Non ABS & Non ABS/EDL is a vacuum servo assisted whether LHD or RHD.

 

2a) ABS Only TEVES 02 hydraulically assisted braking system for LHD.

 

2b) ABS & EDL TEVES 02 hydraulically assisted braking system for LHD.

 

3a) ABS Only TEVES 04 vacuum servo assisted braking system for RHD.

 

3b) ABS & EDL TEVES 04 vacuum servo assisted braking system for RHD.

 

(EDL = traction control)

 

1, 2a & 2b are covered in the yellow USA Bentley manual. 3a & 3b are not. And the instructions in the Bentley manual for 2a & 2b do not apply to the UK RHD Teves 04 braking system.

 

Now the pipe!

 

Arso, youz have a right hooker power plant in a left hooker!

 

Well why didn’t you say :wink:

 

The VR6 vacuum pipe isn’t fitted to the LHD car in any data I hold (Would like to know this is fact from a LHD VR6 owner in original form). I suspect a blank at the manifold but I can’t find that either as a part. Your engine Dutch being a RHD version of the VR6, the pipe is there and has been blanked off as you wrote. It could have been blanked at the inlet manifold but it was probably someone being lazy to do it at the point at the end of the pipe that you can see. So, it isn’t meant to go anywhere cos you don’t have a Teves 04 brake system fitted. The original donor car did, ie. it was RHD. Does that ring a bell when you source the engine?

 

Why the brake differences. Most likely space. Hydraulic servo & ABS & EDL all on the left hand rear bulkhead all fits in. This chosen Corrado brake system would be Teves 02 as most production was LHD. This doesn’t fit behind the engine for a RHD Corrado, so change it and split the system. Hey presto, the Teves 04. Put ABS or ABS & EDL on the left side and slot/squeeze the servo assistance in the behind the engine on the right hand side, servo because the hydraulic assistance unit is too big to go in behind the VR6. The dimension limitations for any Corado model being governed by the VR6 power plant engine bay occupation.

 

I suspect Karman got hung up on the Scirocco RHD complaint of the sssiiinnnkkkiiiinnnggg pedal syndrome. So wanted to avoid a crank and rod conversion system.

 

 

 

how bizarre

 

Kev, It's our ABS / ABS & EDL system that's bizarre......

Thanks for the detailed explaination. It all makes sense now as space is very limited in the VR engine bay, and as you say the RHD version is the bizarre one! 8)

 

As for my engine, I'm not aware it came from a RHD model though as a Corrado specialist garage over here sourced and fitted it for me. All I know is that it took 6 months to find a decent post '94 ABV unit and the one I ended up with was from a rear ended '95 C which is coil packed with 52000 km on the clock. (allegedly anyhow!)

 

Is there anyway to tell for sure? Will ask the garage but it was well over 4 years ago now so doubt they'll remember.
