Meccanocar DOT 5.1 brake fluid – 250 ml – is designed to ensure powerful, consistent and safe braking on hydraulic braking systems requiring a fluid that complies with the DOT 5.1. standard. Thanks to its dry boiling point of over 260 °C and a wet boiling point of at least 180 °C, it effectively limits the formation of vapour bubbles during heavy braking, thereby ensuring consistently precise pedal feel and optimum braking power. Its low viscosity at low temperatures promotes rapid response from hydraulic systems and makes it compatible with the most demanding systems, such as ABS, ASR or ESP. 

This brake fluid is suitable for bicycles fitted with hydraulic disc brakes, as well as for motorbikes, cars and commercial vehicles where the FMVSS 116 DOT 5.1 specification is required. Packaged in a 250 ml bottle, it is ideal for carrying out a full bleed or regular maintenance of your braking system. To ensure it retains its full performance, it is important to follow the manufacturer’s recommendations and never mix it with fluids based on mineral oil, silicone or DOT 5.0.

FAQ – Frequently Asked Questions

1. Is this fluid compatible with all bicycle disc brakes?

No. It is only compatible with hydraulic brakes that use DOT fluid 5.1. Always check your brake manufacturer’s recommendations before use.

2. Can this fluid be mixed with another DOT fluid?

It is not recommended to mix it with mineral oil-based, silicone-based or DOT 5.0. fluids. To ensure optimum performance, carry out a full bleed when replacing the fluid.

3. Why is a high boiling point important?

A high boiling point limits the formation of vapour bubbles during prolonged braking or when travelling downhill, which helps to maintain consistent braking power.

4. Is a 250 ml bottle sufficient for one bleed?

Yes, a 250 ml bottle is generally sufficient to carry out one or more complete bleeds, depending on the type of braking system.

5. Is this fluid only suitable for bicycles?

No. It is also compatible with motorbikes, cars and commercial vehicles that use a fluid meeting the DOT standard. 5.1.
