So I just replaced my wifes brake booster in her 2012 JKU. The original was making a hissing sound mostly when braking hard or when it is cold out. New booster fixed that issue. However now sparatically the "brake" light on the dash comes on sometimes. Also even more importantly now the abs will kick on and off randomly while stopping normal on dry ground. Never did this before replacing booster. Very dangerous as it has made it difficult to stop a couple times almost causing a fender bender. I have no clue how this could be related to a new booster. Can anyone think of something I may have missed when replacing the booster or maybe an idea of what could cause such an issue. Any help is appreciated.
