Problem with brakes solved

[Konstantin Bogach]

Hi listers.
The part of the problem, which is not related to bad bomb, was sticking
proportioning valve.  I took it off and cleaned it, scratched again my head
looking at it wondering how it works(it is second time as I did it once
before on another car),  did not get revelation, put it back on the car,
bled again and brakes became better.
No, it is not because I removed air when I bled it.  There was no air in the
system.
Brakes are still  bad as bomb is dead.  Dilemma is usual:  whether to try to
get hold of  Russell Southerlin  or buy it new?
Another my 200tq has bomb rebuilt by Russell for more than a year and it is
good.  He does good job.
I will try out Aeroequip dealer on Monday.

Thanks.
Konstantin.
