Hi

I heard people were complaining about the reproduction distribution blocks or proportioning valves for the brake system.

I happen to have one of these:

are these the ones that people have been having problems with?

Note that this is just the distribution block (as used on cars with drums on all 4 corners) without the proportionng valve.

Is this the one thats defective??? or is it the proportioning valve that has problems????
