Introduction:
Mountain biking enthusiasts understand the importance of maintaining their bikes, especially when it comes to the braking system. One crucial aspect of brake maintenance is bleeding the brakes, which ensures optimal performance and safety. This article compares the use of mineral oil and DOT fluid in MTB brake bleeding, and discusses the maintenance cycles associated with each.
Mineral Oil:
Mineral oil is a popular choice among mountain bikers for brake bleeding due to its availability and affordability. Here are some key points to consider when using mineral oil for MTB brake bleeding:
1. Compatibility: Mineral oil is generally compatible with most brake systems, including disc brakes and rim brakes. However, it is important to check the manufacturer’s recommendations before using mineral oil in your bike’s braking system.
2. Performance: While mineral oil can provide effective braking, it may not offer the same performance as DOT fluid. This is because mineral oil has a higher viscosity, which can lead to increased brake lever effort and reduced responsiveness.
3. Maintenance cycles: Since mineral oil has a higher likelihood of absorbing moisture compared to DOT fluid, it may require more frequent bleeding. Mountain bikers who use mineral oil in their braking system should expect to bleed their brakes more often, approximately every 500 to 1000 miles.
DOT Fluid:
DOT fluid, also known as hydraulic brake fluid, is a synthetic fluid designed specifically for use in braking systems. Here are some points to consider when using DOT fluid for MTB brake bleeding:
1. Compatibility: DOT fluid is compatible with most modern disc and rim brake systems. However, it is not suitable for some older brake systems, so it is important to check the manufacturer’s recommendations.
2. Performance: DOT fluid offers superior performance compared to mineral oil, providing a more responsive and sensitive braking experience. This is due to its lower viscosity and higher boiling point, which allows for faster and more consistent braking.
3. Maintenance cycles: DOT fluid is less prone to absorbing moisture compared to mineral oil, which means it can last longer between bleeding cycles. Mountain bikers using DOT fluid can expect to bleed their brakes approximately every 2000 to 3000 miles, depending on their riding conditions.
Conclusion:
In conclusion, both mineral oil and DOT fluid have their advantages and disadvantages when it comes to MTB brake bleeding. While mineral oil is more affordable and compatible with a wider range of brake systems, DOT fluid offers superior performance and longer maintenance cycles. Ultimately, the choice between the two depends on the individual rider’s preferences, budget, and the specific requirements of their bike’s braking system. Regardless of the choice, regular brake bleeding and maintenance are essential for safe and enjoyable mountain biking experiences.
