Will air in brake lines cause caliper to stick?
The air in the brake line can cause a brake caliper to stick. Mostly, this occurs when the brake hose collapses internally. As a result of this, whenever pressure is applied on the brake pedal, it will shove the brake fluid such that the braking system will function.
