REFLECTOR: Parking Brake

[Jim Agnew]

Hi Chuck,

I agree and have the same setup.  I got tired of the small capacity of the brake 
fluid so designed and made the following

  dual feed racing resivore that holds about a pint of fluid.  Thought you might 
be interested.

I have had this type of valve (mine is a Parker) for over 10 years, and it has 
worked well. You step on the brakes and then move the lever to trap (and lock) 
the brake fluid (and pressure) going down to the disc brakes. I use a cable pull 
and lock (same as front oil cooler vent control). I’ve bled the brakes and it 
hasn’t been a problem. I have the Toyota twin master cylinders that use Dot 5 
silicone based brake fluid (MIL-B-46176), but it is compatible with MIL-H-5606. 

 
I think it should be standard on all V’s because you can lock the brakes while 
you do your run up,  are on uneven slopes, if there is wind, etc. I see it as a 
safety feature, and use it all the time.
