I have the dreaded hiss from the brake booster at the brake pedal. I believe the diaphragm at the brake boot has a crack, and the brake pedal/brake booster hisses when not depressed. Super frustrating. Does anyone have a FSM or a step-by-step to help show the process of replacing the brake booster/pedal assembly? I know I need to remove the engine fuse box and a host of other things, just some direction would be great. Thanks in advance.
