Car Drum Brakes

Some vehicles use a drum brake system on the rear that combines the hydraulic brake system with a parking brake mechanism. Drum brakes tend to be less expensive to manufacture, but are also less precise than disc brakes, and tend not to be used on vehicles with anti-lock braking systems. Failures of drum brakes include routine brake shoe wear –as the friction material on the brake shoes wear away slightly each time the brakes are applied.  The hydraulic wheel cylinder that applies the brakes can develop leaks in the seals, and the springs and clips inside the brake drum that hold the parts in place can become rusted or broken. Parking brakes incorporate an auto-adjusting mechanism that can also fail and require replacement. Regular brake inspections will help to make sure all the components in the drum brake system are functioning correctly.
