Bright Eyes (1934) An orphaned girl is taken in by a snobbish family at the insistence of their rich, crotchety uncle, even as her devoted aviator godfather fights for custody.
A loose parking brake is another symptom of bad or failing brake shoes. For vehicles equipped with drum brakes, the brake shoes are what hold the vehicle in place when the brake is engaged. If the shoes become worn or dusty, they may not be able to hold the weight of the vehicle without slipping.
When you apply the brakes, brake fluid is forced under pressure into the wheel cylinder, which in turn pushes the brake shoes into contact with the machined surface on the inside of the drum. When the pressure is released, return springs pull the shoes back to their rest position.
