While disc brakes are becoming the norm these days, rim brakes still hold their ground, especially for riders on a budget or those chasing lightweight setups. Rim brakes have a simple structure, low maintenance costs, and are easy to work on—swapping brake pads or adjusting cables is straightforward, making them ideal for daily commuting or casual rides. Plus, they’re usually lighter than disc brakes, which is a big plus for road bikes or racing models. That said, their stopping power and reliability take a nosedive in wet or muddy conditions—that’s their main downside. If you ride a lot in the rain or need stronger braking, disc brakes are the way to go. Both have their pros and cons; choosing between them boils down to your riding needs and budget. It’s worth noting that many entry-level bikes still come with rim brakes, while higher-end models mostly feature discs, but as technology improves, disc brake costs are dropping, so they’ll probably become even more common down the line.

Some economy cars and commercial vehicles still use drum brakes these days, especially in their rear braking systems. This design mainly comes down to cost control and durability—drum brakes have a simpler structure and lower maintenance costs, making them a solid fit for situations where braking performance isn’t the top priority, like city commuting or light-duty trucks that don’t haul heavy loads. While modern passenger cars have mostly switched to disc brakes for better heat dissipation and stopping power, drum brakes still hold their own in specific models. They offer longer pad life and better resistance to dust and water, which is handy in rainy, humid climates. Interestingly, some hybrid and electric vehicles also use drum brakes on the rear wheels because the regenerative braking system handles most of the stopping force, so the rear brakes don’t bear as much load. If you’re thinking about buying a vehicle with drum brakes, it’s a good idea to test-drive it to get a feel for the braking performance. Also, make sure you know the key maintenance points, like cleaning out dust from the brake drums and checking pad wear, to keep things safe on the road.

The principle of aircraft wheel braking system is similar to that of car braking, but the design is more complex, mainly used for landing deceleration, ground taxi control, and parking fixation. Modern aircraft often use multi disc carbon fiber brake components, driven by hydraulic or electric systems, with high temperature resistance and strong heat dissipation. For example, the carbon brake discs of the Boeing 787 can withstand temperatures exceeding 1500 ° C. Compared to single disc brakes in cars, airplane brakes need to handle higher loads, so multiple brake discs are stacked together to create frictional resistance during braking by pressing the discs with an actuator. Interestingly, some aircraft models such as the Airbus A380 are also equipped with anti-skid systems (similar to car ABS) to prevent tire lock up and skidding. The energy conversion of aircraft braking is astonishing, and the heat generated during a heavy landing is enough to boil several tons of water, so the cooling time of braking is also a key focus of ground inspection. During maintenance, it is necessary to regularly measure the brake wear indicator pin, which is similar to the principle of detecting the thickness of automotive brake pads. It is worth mentioning that some military transport planes, such as the C-17, can even achieve 180 degree stationary steering through reverse braking, which is not yet widely used in the civilian field.

The cost of replacing the wheel cylinder is usually between RM200 and RM800, depending on the vehicle model, brand, and the choice of repair shop. Original parts may be more expensive but have better quality assurance than aftermarket parts, while prices at roadside shops may be lower than those at authorized repair centers but there may be differences in service and technical level. The brake cylinder is an important component in the drum brake system, responsible for pushing the brake pads into contact with the brake drum during braking. If there is oil leakage or jamming, it can cause brake failure or dragging. Therefore, once the brake pedal becomes soft or the braking distance becomes longer, it should be checked in a timely manner. In addition to the cost of replacement, it is recommended to also check the condition of the brake oil and consider replacement, as old brake oil may contain moisture or impurities that affect brake performance. It is usually a reasonable maintenance cycle to replace brake oil every 2 years or 40000 kilometers. If the vehicle has traveled over 100000 kilometers, it is also possible to consider checking the wear of the brake drum and brake pads, as excessively worn brake pads can accelerate the damage of the cylinder.

A three wheel braking system typically refers to a braking device designed for three wheeled vehicles, including traditional three wheel motorcycles, electric tricycles, or special-purpose three wheel cars. The braking configuration may vary depending on the vehicle's purpose, such as a combination of disc brakes on the front wheels and drum brakes on the rear wheels, or hydraulic disc brakes on all wheels to improve braking efficiency. Compared with four-wheel vehicles, tricycles require more attention to brake force distribution due to the lack of one contact point. Some high-end models are equipped with ABS anti lock braking systems to prevent slipping on wet and slippery roads. It is worth noting that the maintenance cycle of tricycle brakes is usually shorter than that of cars, especially for heavy-duty tricycles, which require frequent inspection of brake pad wear and hydraulic oil status. When upgrading brakes, modification enthusiasts should pay attention to matching the original specifications to avoid the risk of rollover caused by imbalanced brake force distribution. In addition, with the popularization of electric vehicles, some new electric tricycles adopt energy recovery braking technology, which can convert kinetic energy into electrical energy during deceleration. This hybrid braking mode relies less on traditional brake pads, but regular inspection of mechanical brake components is still a necessary safety measure.
