My 86 gn has vacuum assist brakes and they dont hold boost very well at all. Im wondering if anyone else has one of these setups and if they know how to make them work.
I had the same problem... Turns out all I needed was a new check valve... I think you can test them by blowing into both sides... One side should flow air and the other shouldnt... They have them in the Help! section at AutoZone... Here is what they look like.. Amazon.com: Dorman HELP! 80190 Brake Check Valve: Automotive
You might get more help with this probelm if you post this under the General Tech section insted of HYBRIDS.....
