Despite its advantages, the integral drum parking brake system also has its challenges. One of the most notable concerns is the potential for rust and corrosion, particularly in regions where road salt is commonly used during winter. Regular maintenance is required to ensure that the components remain in good condition and operate effectively. Additionally, while drum brakes can provide significant holding power, they may not always deliver the same level of performance as disc brakes in high-performance situations. This has led some manufacturers to opt for disc-based parking brake systems in certain models, particularly in high-end or performance-focused vehicles.
