I couldn’t find any info on the legalities of running a brake shut off valve (not a line locker) to the rear brakes.
Obviously a road car cant have the braking bias able to be altered in cabin while being used on public roads (as is the case with bias adjusters/proportioning valves) but what if its a dedicated motorsport vehicle? Or can i have the lock out valve setup there but just make it inoperative when the car is to be used on the road?
The car will also be fitted with a Wilwood pedal box with balance bar which has the provisions to lock any adjustments.
Cheers.

Gidday Slideways It must utilise an electrically operated, purpose built, automotive brake system component that uses automotive brake parts. It must be operated by a momentary switch that disengages when the switch is released, it must also have a light that shows the driver the system is activated. I do not believe it would be covered by a Motorsport Authority Card so will always need to be temporarily enclosed or disabled from being used while on public roads. Also, of course it must be certified by an LVVTA certifier. Edit - reading your message again, I gather you might be referring to a ball valve like this picture below. Without knowing for certain how these valves work, I do not believe they could be considered a bias valve, and is instead just a mechanically operated line-lock. A line-lock like this does not meet the requirements as listed above.  Cheers Chris |

Hi Chris, Thanks for the reply. Yes what i have and want to use is a Wilwood electric solenoid valve made specifically for this application. When in operation, it still allows any pressure that was in the line to return to the master cylinder.
Will having a momentary toggle switch behind a rocket style cover suffice as enclosed enough for the road? If not can the fuse to that system be pulled and it then be ok seeing as its them completely disabled?
Thanks

The toggle switch must be isolated so it is not accidentally turned on when on the road, a toggle switch cover would work if set up correctly, but to be extra safe, pulling the fuse also would be wise.
