I took mine off and the brakes have never been so good I'd either fit a balance bar if you wanted the adjustment or ditch it

[Guest nightracer35]

thanks for your reply, i dont have 1 fitted but been told would be better if i did have 1.

Hi ,I fitted one ,but had it near level , i cut a slot in the mounting plate so i could adjust it, doing this way the rear brakes don't lock up during the sva test.

Are we talking about the original Sierra brake compensator valve?, as I have often wondered about this myself…….

 

From what I understand the Sierra valve is an inertia device, limiting pressure to the back brakes under heavy deceleration when the weight is transferred to the front wheels.

As such it will have no effect during a roller brake test (as in SVA) as there is no actual vehicle deceleration and no weight transfer, hence the limiting device will not operate?

 

Can anyone confirm or deny the above?, am I misunderstanding the operation of the device?............

My understanding is that if the vave is fitted, they have to test the brakes 'out in the car park'.

If it's not fitted, the test is done on the rollers.

 

A Robin Hood will stop well enough, but not dive. It's a combination of the two that operates the valve (allthough it can be mounted at whatever angle to compensate for little dive).

 

I think the general consensus is not to fit it.

Fitted mine. Brakes tested on the rollers at SVA not in the car park. Having braked enthusiastically a few times I have never had the rears lock up before the fronts. Fitted it in the tunnel at the same angle as the sierra.

Maybe, if you fitted it in the tunnel, the SVA man didn't see it and so didn't think one was fitted?

thanks for all your advice and suggestions i think i will leave it off as some suggest.

I decided it was best to own up before the brake test. I have to admit I had heard that the test was easier to pass with the valve fitted!?

Hi All,.

 

I havent fitted mine either but I was going to ask if anyone has left the servo out too ?

 

I've assisted with the build of two Westies in the last few months and we didnt fit the valve or a servo to either but we did use the Westfield brake master cylinder supplied by Westfield in each build.

 

Comments appreciated.

Oh darn it! I just knew you were going to say that. hummm

We left out the servo and are very happy without it

 

So happy in fact the next 2 Hoods wont have one either

do you have 240 or 260mm front discs Bill? I tried it and din't like it at all, found it had no feel when close to locking up, and i needed to jump on it to get it to stop!
