Jeff,

I fitted the decelleration valve to my Robin Hood, it was noted by the tester who was pleased to see it fitted, who said it would help with the test.

I have also fitted it to my Sumo, (see build pics on my web site), just to be on the safe side. I have Granada disks all round.

Same as me. Had it on the Robin Hood, and I now have it on my Granada set up on the Sumo.

Is this a standard progression in the kit car world; Robin Hood to Sumo to ??????

:D

I have scorpio disks all round, and was actually planning on installing a brake decelleration, but can someone tell me what type/brand, and how to install it ?

The guy at Pilgrim here in Belgium told me he never installed one of those on any of the Sumo that he builds.

Jeff,

you're not wrong! Entering and leaving roundabouts is just not the same in the diesel car I am running at the moment! }( I am really looking forward to getting out and about in the Sumo. I plumped for the 2.9i V6 scorpio and am getting fairly close to start thinking about SVA paperwork.

I took the Pilgrim manual at it's word.

It said as the car is light it isn't needed, didn't see the point in making more work for myself.

But, I did keep hold of it from my donor, just in case.

What's it for / does it make any difference ?

Will the car pass the SVA without it ?

My Sumo certainly needed one for SVA. Rears would lock up each time before the fronts without it. Now with it fitted, works a treat.

Cheers,

I was told by Tony Holmes that if you are using the Granada set up you don't need to fit one, but that it is advisible on the Sierra set up.
I have the Granada set up and passed SVA 1st time with no problems at all.
From memory I believe that Tony B has the Sierra set up on his, which is why he needed to fit the valve,:tu :tu :tu :tu :tu :tu

Good job I've got the Granada set up!!

Lucky sod, I've got the Sierra !

Any chance it'll pass the SVA without, if so where's best & how to fit it ???

The only info I have is that I've seen people attach them to the lower chassis rail in the engine compartment on the drivers side before the single pipe runs towards the rear of the car. I think you are also meant to fit them at a specified angle.

Best of luck.

Attached a pic of where my deceleration valve is fitted. It is angled forward at around 30-40 degrees. Brake pipe from the master cylinder fits to the rear of the valve. Line then comes from the front of the valve to the rear of the car. Simple enough to fit.

Let me know if you have any other questions.

Cheers,
Tony B

This might do me a favour. I've fed the brake line down the inside of the transmision tunnel and the bend into the tunnel looks crap. I took the 12" clip SVA rule literally ie servo to chassis so it's all scrunched up ( SVA guide book already on order ! )

I think I'll cut this and mount the valve in the entrance to the transmission tunnel. Any idea how many inches un-clipped you're allowed under SVA between the valve or chassis before the servo. If it is 12" it means a very tight bend back to the chassis and looks crap.

Jon,

Don't forget that the pipe will be secured at both sides of the valve, so take 30cm either side of that. You should be easily able to bend/shape the pipe within that sort of distance.

Cheers,
