To bias or not to bias? That is the question...
scoobyis2cool - 14/11/03 at 09:58 AM

Have people found that their Indys need a brake bias valve or not? I'd like to fit one but I'm not paying £70 for a new one and haven't had much luck at the local scrappy either. I was looking for an uno valve but the only uno they had was at the top of a huge teetering pile of cars and I wasn't climbing up that! Anyone got any other ideas?

Cheers,

Pete

Thanks, I'll have a look for them, have they got a website?

I searched for them and it found www.ggbengineering.co.uk but the page didn't load, have they moved site?

Pete, don't bother putting one on and save yourself a few quid.

Pete,

I think that the engine choice will influence whether one is needed or not as it will affect the axle loading ratio. The aim is to ensure that the front wheels lock before the rear, the more weight on the front the more the need to limit the rear braking, i.e. pinto as opposed to bike, but not too restricted that it doesn't reach the reuired braking effort.

One of the other problems is that of bedding in. I ran in my new discs and pads on my road car.

Mines got a pinto and I fitted one from a scrap Mondeo as I couldn't locate a Fiesta. Passed SVA ok. See also http://www.locostbuilders.co.uk/viewthread.php?tid=4420

If you fit an adjustable one there are requirements for SVA that it cannot be adjusted.

Cheers,

Colin

sierra's have one located in the engine bay.

Suzuki 4x4 jeeps have one located near the flexi on the rear axle,


By the way I fitted the sierra on to my indy.

Forgot to mention that point!


scoobyis2cool - 14/11/03 at 04:15 PM

how exactly does the sierra one work? does it have to be mounted at a particular angle or can it be mounted any way up? i assume its not adjustable either?

Pete


theconrodkid - 14/11/03 at 04:51 PM

its an inertia valve.only works when you slow down so wont show up on rollers,has to be mounted at the right angle


Peteff - 14/11/03 at 05:09 PM

Also only works when the angle changes so unless your car has the same springing as a Sierra it will be useless.

yours, Pete.

So do you think my pinto engine'd indy will need one?
