I did everything to the brake system I had the master cylinder done I had the breaks of course done also back breaks had them re bled numerous of times in between I read about the booster it’s not my booster cause when car turn on peddle go down! What else can it be I had no brake fluid loss had this car for 3yrs an just really putting work into now but this prob started not long ago an I just been tryna keep up with it I also had my calibers changed on both side I had a leak on my drive side an had to replace it and 1 time soon as I got my brakes done it broke so had to get another set an change it again 🤦🏽‍♀️ I’m just at a loss an I hope I explain this right!!

 

What is going on?

Is the brake peddle going to the floor when the engine is started?

Was the repair work done by a shop or you?
