Default Wanted - Brake Pressure Reducing Valve

Hi

Has anyone got one of the standard brake pressure reducing valves they don't want?

I've got discs all around and need something to reduce the rear line pressure.

Thanks
Matt

Are they the straight pressure reducing valves, or the deceleration sensitive ones?

Late reply,pressure reducing personally I would avoid anything speed sensitive as it would be for a larger heavier car and possibly a problem.

Fiat Uno ones are available from factors very cheaply, they can be made adjustable very easily, made unadjustable for IVA, and then returned to the original state!

I bought one of those (from Brakeparts, part #HRV1013), but I can't work out what I would need to do to make it work correctly - do you have the details?

That's why I was looking for the standard Sierra one - as far as I can tell it just shuts off the rear brakes when the decelleration reaches a certain rate. It may not be optimal, but seems from comments that as long as it is mounted identically to the Sierra then it is enough to pass the IVA.

Roller brake tester does not take into account deceleration only brake effort/force so could cause a fail at test/IVA.
