This may be related to your brake booster failing or potentially a vacuum leak in the braking system. Your braking system works on hydraulic pressure that is maintained through a series of processes that create this hydraulic pressure that begins with the brake booster. When this is not working properly, this may suggest that you have a leak or the booster itself may be failing. I would recommend having an expert from YourMechanic come to your location to diagnose your braking system.
