2010 Mazda 6. Car breaks will not push in or work mostly first time it is driven. literally will not push in. is this a known issue? What could cause it?
If I’m reading this correctly and your brake pedal is very hard to press when you first start the car, you likely need a new “brake booster”. Power brakes need vacuum to work, and it sounds you have a vacuum leak in your booster.
If you are asking if it specific to your vehicle No . Brake problems can happen to any vehicle . As for cause that is for a brake shop to find out and repair if you don’t know how to repair brakes.
