I am experiencing a hard brake pedal about every other day if the car sits overnight. I know I am not depleting the vacuum supply before I exit the vehicle by pressing the brake pedal. Some mornings the pedal is very hard and barely moves and other mornings it's normal. My brake booster vacuum check valve hose assembly was replaced to try and fix the problem but it still does it. I also know my electric vacuum pump works correctly. Anyone else experiencing this? Is it normal? Do I have a small leak in the brake booster vacuum diaphragm? I have no other brake feel issues.
Just curious if anyone has been able to fix this yet.
