Can anyone help? From: seanmundy at hotmail.com To: detomaso at poca.com Subject: Brake Booster Check Valve Date: Tue, 9 Apr 2013 10:01:03 -0700 I think I have a bad vacuum check valve on my brake booster. I've checked the Pantera parts list but didn't find another cross referenced part#. Anyone know of an alternate?
