Can you bleed brakes with wheels on?
If you can get to the bleeders with the wheels on it’s no prob
. Most vehicles you are supposed to do one rear wheel then the front wheel diagonal from it. When I do a system flush at home I just “gravity bleed” them. Meaning I just open all the bleeders at the same time and top off the master cylinder periodically.
Will air in brake lines work itself out?
It won’t get better on its own
, and it could get worse – eventually, a bunch of small air bubbles in the line will join together to become one big, dangerous bubble. So your brakes won’t have their normal pressure – and they could fail entirely, McGraw says.

Do You Have To Pump The Brakes After Adding Fluid
YES.
You HAVE TO pump the brakes to push the fluid back through the system when you have finished

rapidly pump the brake pedal with your foot
. Even if there is a defect in your braking system, this can usually generate enough pressure to stop safely on the side of the road.
What does it mean when the brake pedal is hard to push down?
Vacuum Pressure.
Vacuum – or really lack of vacuum pressure
– is the most common cause of a hard brake pedal, and therefore the first thing to look at when a hard pedal is present. Any brake booster (whether from Master Power or any other supplier) needs a vacuum source to operate.
Why is my brake pedal hard before I start my car?
The most common reason for a hard pedal is simply
not having enough vacuum pressure
. A brake booster not functioning correctly can cause this problem. When the brake booster is stopped, the engine pulls a vacuum on both sides of a diaphragm. This happens along with a two-way valve in the middle of the booster.
