Worn or damaged brake shoes: Worn brake shoes can cause the brake fluid to leak from the wheel cylinder. The brake shoes press against the brake drum to slow down or stop the vehicle. When the brake shoes are worn out, they can no longer create enough friction to stop the vehicle effectively. This can cause the brake fluid to leak from the wheel cylinder.
Damaged wheel cylinder: The wheel cylinder is responsible for actuating the brake shoes. When the brake pedal is depressed, the master cylinder sends brake fluid to the wheel cylinders, which in turn force the brake shoes against the brake drum. A damaged wheel cylinder can cause the brake fluid to leak from the wheel cylinder.
Loose or damaged brake lines: The brake lines carry brake fluid from the master cylinder to the wheel cylinders. Loose or damaged brake lines can cause the brake fluid to leak from the wheel cylinder.
Faulty brake master cylinder: The brake master cylinder is responsible for creating the hydraulic pressure that forces the brake fluid to the wheel cylinders. A faulty brake master cylinder can cause the brake fluid to leak from the wheel cylinder.
To fix a brake fluid leak from the rear wheel drum, you will need to:
-Inspect the brake shoes and replace them if they are worn out.
-Inspect the wheel cylinder for damage and replace it if necessary.
-Inspect the brake lines for leaks and replace any damaged lines.
-Inspect the brake master cylinder for leaks; replace it if necessary.
Additionally, it is essential to regularly inspect the brake fluid level and top it off as needed. Low brake fluid levels can cause the brake fluid to overheat and damage the brake lines and wheel cylinders.
