To remove oil from the brake disc without replacing the discs or pads, you can try cleaning the affected area with a degreaser specifically designed for brake components. Use a clean cloth or paper towel to wipe off the excess oil. You can also lightly sand the surface of the brake disc to help remove the oil residue. Additionally, you can heat the brake disc by driving the vehicle at high speeds and then applying the brakes to burn off the oil. **

No, the brake disc and brake pads do not touch during normal driving. When the brake pedal is pressed, the brake pads are squeezed against the brake disc, creating friction that slows down the vehicle. However, when the brake pedal is not being pressed, the brake pads are not in contact with the brake disc, allowing the wheels to spin freely. This design prevents unnecessary wear and tear on the brake components and allows for efficient and smooth driving. **

One method to remove oil from brake discs without replacing them is to use a degreaser specifically designed for brake components. This can help break down and remove the oil residue. Additionally, sanding the brake discs lightly with fine-grit sandpaper can help remove the oil buildup. It is important to thoroughly clean the discs after using these methods to ensure proper brake function. **

Yes, it is important to choose the correct brake pads for a mechanical disc brake based on the type of disc being used. Different disc materials (such as stainless steel, aluminum, or carbon) and surface finishes (smooth or textured) can affect the performance and wear of the brake pads. Using the wrong type of brake pads can lead to reduced braking power, increased noise, and premature wear on either the pads or the disc. Therefore, it is recommended to select brake pads that are compatible with the specific disc being used for optimal braking performance. **

To determine if the brake pads are too close to the disc, you can visually inspect the gap between the brake pads and the disc. There should be a small gap between the pads and the disc when the brakes are not engaged. If the gap is too small or if the pads are making contact with the disc even when the brakes are not engaged, then the brake pads may be too close to the disc. This can lead to premature wear of the pads and discs, as well as reduced braking performance. If you suspect that the brake pads are too close to the disc, it is best to have a professional mechanic inspect and adjust the brake system as needed. **

The Tektro Novela mechanical disc brake uses semi-metallic brake pads. These pads are made from a combination of metal and organic materials, providing a good balance of durability, heat resistance, and braking performance. They are commonly used in mechanical disc brakes for their reliable stopping power and long-lasting performance. **

The distance between the brake pads on disc brakes is designed to be close enough to effectively grip the rotor and provide sufficient stopping power. If the brake pads are too far apart, they may not be able to effectively engage the rotor, resulting in reduced braking performance. However, if the brake pads are too close together, they may rub against the rotor, causing unnecessary wear and potentially leading to overheating and reduced braking efficiency. Therefore, it is important for the brake pads to be properly adjusted to ensure optimal performance and longevity of the braking system. **

Whether you need to replace just the brake pads or the brake disc as well depends on the condition of both components. If the brake pads are worn out but the brake disc is still in good condition, you may only need to replace the brake pads. However, if the brake disc is warped, scored, or worn down, it is recommended to replace both the brake pads and the brake disc for optimal braking performance and safety. It is best to have a professional mechanic inspect both components to determine the best course of action. **
