The recommended frequency for bleeding disc brake oil on a bicycle depends on several factors, including the type of brakes, conditions of use and personal preference. However, there are some general guidelines you can follow.
In general, it is recommended to bleed your hydraulic disc brakes every 6-12 months, depending on the intensity of use. If you use your bicycle more aggressively, on rough terrain or in wet conditions, you may need to bleed more frequently, e.g. every 3-6 months.
In addition, it is important to pay attention to signs of brake system problems, such as oil leaks, a brake lever that feels soft or touches the handlebars too easily, or a loss of braking power. If you notice any of these symptoms, you may need to bleed even earlier than the recommended period.
Keep in mind that bleeding disc brakes is an operation that requires some technical expertise. If you have no experience in carrying out this maintenance, it is advisable to take your bike to a specialised shop or have it serviced by a qualified mechanic.
What type of oil should be used for disc brakes on a bicycle?
To determine the type of oil to use for bleeding the disc brakes on your bicycle, it is essential to refer to the specifications recommended by the brake manufacturer. Different brake systems may require oils with different characteristics.
Generally, hydraulic disc brakes for bicycles use mineral or synthetic oils. Mineral oils are commonly used in many disc brake systems, but some manufacturers also recommend the use of synthetic oils of a specific quality.
It is important to use the brake manufacturer’s recommended oil as different oils can have different viscosities and chemical properties, which can affect the performance of the brake system and its durability.
The specification of the recommended oil can be found in your bicycle manual or on the website of the brake manufacturer or complete assembly. Often, the recommended oil is also indicated on oil bottles sold as spare parts for brake systems.
