To the brakes gurus:

        I have a ' 90 Westy (USA version) and have checked the brakes:
*       Changed the slave rear right cilinder (it was leaking).
*       Changed the front pads.
*       Bleeded the system twice.
        But I�m still not satisfied, it feels like only the front brakes are
working. 
        Some years ago I had an ' 85 Transporter (German version) and did'nt
have 
        any trouble with brakes, as a matter of fact it performed quite
good. The rear 
        wheels only lockup once in a "panic stop" on a wet road. 
        Last month there were some postings refering to the (BPV), so these
are my 
        questions:  
*       Do all Vanagons/Transporters have that valve, or only USA models?
*       How can I tell if it is working the way it is supposed to?
*       If it's not working or clogged, what happens if I get rid of it?

Thank you in advance!
