I need help
I've searched all over the Internet and can't find answers
my issue is that no matter how many times I bleed I can't get pressure in the brake pedal. I've replaced the main lines coming off the master cylinder and the booster and master cylinder. When I pump the brakes pressure builds and holds but when I pump their a "psst" noise coming from abs module but I can't find a leak anywhere. Also when I turn key the and module doesn't make the buzzing noise it normally does any ideas?
