No, not all brake lines are superficially rusted. The extent of rust on brake lines can vary depending on factors such as the age of the vehicle, the climate it is exposed to, and how well it has been maintained. It is important to regularly inspect brake lines for any signs of rust or corrosion, as this can compromise the integrity of the brake system and lead to potential safety hazards. **

Steel braided brake lines offer several advantages over regular brake lines on motorcycles. They provide increased durability and resistance to wear and tear, which can result in a longer lifespan and reduced maintenance costs. Additionally, steel braided brake lines offer improved brake feel and responsiveness, allowing for better control and modulation of braking power. They also have a higher tolerance for heat and pressure, making them less likely to expand under heavy braking, resulting in consistent performance. **

It is not recommended to preserve brake lines with grease. Grease can attract dirt and debris, potentially causing damage to the brake system. It can also affect the performance of the brakes by reducing friction between the brake pads and rotors. It is best to use brake line-specific lubricants or follow the manufacturer's recommendations for preserving brake lines. **

The brake pedal may feel soft if there is air in the brake lines, which can cause a spongy or mushy feeling when you press the pedal. This can happen due to a leak in the brake system or if the brake fluid is low. When the brake pedal feels soft, it can indicate a problem with the braking system that needs to be addressed promptly to ensure safe driving conditions. It is important to have the brake system inspected by a professional mechanic to diagnose and fix the issue. **

No, the brake pedal should not be fully depressed as this can cause the brakes to lock up and potentially lead to loss of control of the vehicle. The brake pedal should be pressed firmly and steadily to slow down or stop the vehicle safely. It is important to apply gradual pressure to the brake pedal to allow for smooth and controlled braking. **

No, mountain bikes typically do not have a pedal brake. Mountain bikes are usually equipped with hand brakes, either disc brakes or rim brakes, which are operated by levers on the handlebars. These types of brakes provide better control and stopping power, especially in off-road and mountainous terrain. Pedal brakes are more commonly found on cruiser or city bikes, where simplicity and ease of use are prioritized over performance. **

The clacking noise when releasing the brake pedal could be due to a few different reasons. One possibility is that the brake pads are not releasing smoothly from the rotors, causing them to make a clacking sound as they move. Another potential cause could be worn or loose brake components, such as caliper hardware or anti-rattle clips, which can create a clacking noise when the brakes are released. It's important to have a professional mechanic inspect and diagnose the issue to ensure safe and proper functioning of the brakes. **

After an emergency brake, the cyclist supports himself by using their legs to stabilize the bike and prevent it from tipping over. They may also use their arms to hold onto the handlebars or nearby objects for balance. It is important for the cyclist to stay alert and ready to react to any sudden movements or changes in the environment to avoid falling or getting injured. **
