I've noticed lately driving my tahoe that when braking, I hear a whooshing air noise from firewall area under dash. Within the last few days, it has happened when hitting brakes hard and I can hear the air noise constant when my foot stays on the brakes. Also, the brakes are stiff if that makes sense almost as if they are not wanting to stop. And I almost have to stand on brake pedal to stop truck. But it is intermittent as far as that scenario, meaning brakes not working properly. But the air whooshing noise is every time I apply brakes. If I am slowing down in enough time brakes work decent but spongy. But at least I stop safely. So, my question is this the brake booster taking a dump on me or something else. Research I've done thus far mostly points to that being the culprit. Any suggestions are much appreciated!
