Brake discs, slotted, ventilated, drilled
Brake discs are a crucial part of a vehicle's braking system and there are different types offering various features and benefits. Amongst the most common are the scored, ventilated and drilled brake discs, each designed to fulfil specific functions. In today's SDT BRAKES blog, we will explore the characteristics of each type:
Brake discs, slotted, ventilated, drilled
Slotted brake discs
Characteristics: These discs have grooves on their surface, arranged in the form of stripes. This design has several functions, such as improving the dispersion of heat and gases generated during braking.
Benefits: The main advantage of the grooved discs is their ability to reduce overheating. The grooves allow better ventilation and heat dissipation, which helps to maintain the efficiency of the braking system.
Ventilated brake discs
Characteristics: Ventilated discs have internal channels or fins that allow for increased air circulation. These fins are located between the two disc surfaces.
Benefits: The improved ventilation helps to cool the disc quickly during braking, preventing overheating. This is especially beneficial in heavy braking situations, such as descending steep slopes or towing heavy loads.
Perforated brake discs:
Features: these discs feature drilled holes along their surface. These holes are strategically placed and do not go all the way through the disc.
Benefits: The main advantage of perforated discs is their ability to disperse gases generated during braking, thus improving the efficiency of the system. On the downside, however, they tend to crack easily.
Comparison between slloted, ventilated and drilled brake discs:
Heat dissipation
- Striped: improves heat dissipation, but not as much as ventilated ones.
- Ventilated: offer excellent heat dissipation due to internal fins.
Coping with overheating
- Striped: help prevent overheating, but to a lesser extent than ventilated.
- Ventilated: ideal for heavy braking situations, preventing overheating.
Vented: ideal for heavy braking situations, preventing overheating.
Vented: also helps prevent overheating.
- Perforated: also helps prevent overheating, but less so than ventilated ones.
Perforated: also helps prevent overheating, but less so than ventilated ones. Durability
- Lined: have good durability, but can wear more quickly under extreme conditions.
- Ventilated: tend to have a long service life due to their ability to stay cooler.
- Perforated: may have a slightly shorter service life, especially under heavy use. As they tend to crack easily. Performance in wet conditions
- Lined: maintain good performance in wet conditions, but may generate more noise.
Vented: offer good performance in wet conditions. - Ventilated: offer good performance in the rain, with less likelihood of noise.
- Perforated: may experience a slight loss of performance in wet conditions. Noise during braking
- Scuffed: may generate more noise than the other types.
Vented: less likely to generate more noise than the other types.
- Ventilated: less likely to generate noise during braking.
- Perforated: may experience some noise, but to a lesser extent than scored discs. In summary, the choice between lined, ventilated and perforated brake discs will depend on the driver's individual needs and preferences.
Consequences of not renewing and maintaining your brake discs
Neglecting the proper maintenance and renewal of brake discs can have a number of consequences that compromise not only the safety of the vehicle, but also the safety of those who occupy the vehicle and share the road.
1. Decreased braking efficiency:
Over time, brake discs experience natural wear due to constant friction with the brake pads. If not properly replaced, this wear can affect braking ability, resulting in a decrease in braking efficiency. This prolongs stopping distances and compromises the ability to stop the vehicle safely.
2. Overheating and uneven wear:
Lack of brake disc renewal can lead to overheating during prolonged braking, which contributes to uneven wear of the disc surface. This not only compromises braking performance, but can also lead to annoying vibration and noise during braking.
3. Increased brake pad wear:
Worn or damaged discs can put additional pressure on the brake pads. This not only accelerates pad wear, but can also lead to premature wear of other brake system components, increasing repair costs.
4. Risk of vibration and noise:
5. Uneven wear and lack of renewal can generate annoying vibrations and noises during braking. These are indicators of brake system problems and can adversely affect the driving experience.
5. Compromised road safety:
The most significant consequence of failing to renew and maintain brake discs is the compromise of road safety. An ineffective braking system increases the risk of accidents, especially in emergency situations where a quick and efficient response is crucial.
6. High repair costs:
Postponing brake disc maintenance can result in higher repair costs in the long term. The need to replace other brake system components and possibly more extensive repairs can generate significant expenses.
As we can see, failure to renew and maintain brake discs not only affects the performance of the braking system, but also puts road safety at risk. Constant vigilance and attention to maintenance are key to ensuring an efficient and safe braking system.
Conclusion
It is important to keep in mind that each type of brake disc has its pros and cons, and the choice between them will depend on the driver's preferences, type of driving and specific conditions of use. In addition, it is crucial to follow the vehicle manufacturer's recommendations as to the type of brake discs to use in order to maintain optimum performance and ensure safety on the road.
