## Summary description

WELDTITE Brake Fluid Mineral Oil 1 L is a one-liter container of mineral-based hydraulic oil for bicycle brake systems. Supplied by WELDTITE, this mineral oil is intended for use in compatible hydraulic brake calipers and levers.

## Long description

WELDTITE Brake Fluid Mineral Oil 1 L is a one‑litre container of mineral-based hydraulic oil formulated for use in compatible bicycle hydraulic brake systems. The product is intended for bleeding, topping up and routine maintenance of brakes that specify mineral oil rather than DOT brake fluids. The neutral formulation is designed to work with mineral-oil calipers and levers, supporting consistent brake feel and dependable system performance when used according to manufacturer guidance.
Advantages
This mineral-based brake fluid is supplied in a practical 1 L container suitable for workshop use and extended servicing tasks. The fluid is chemically compatible with brake systems that require mineral oil, reducing the risk of seal deterioration that can occur when incompatible fluids are used. Its stable formulation helps maintain predictable hydraulic response and assists in efficient bleeding and removal of air from the system.
Suitable for
 Bleeding hydraulic bicycle brakes that specify mineral oil
 Topping up reservoir levels on compatible calipers and levers
 Workshop maintenance and professional brake servicing
 Home servicing by cyclists familiar with hydraulic brake procedures
Key specifications
 Volume: 1 litre container suitable for multiple service operations
 Base: mineral oil formulation designed for bicycle hydraulic systems
 Intended use: bleeding, topping up and routine maintenance of mineral-oil brake systems
 Compatibility: for use only in systems that specify mineral oil (not suitable for DOT brake systems)
 Storage: keep sealed and stored in a cool, dry place away from direct heat and ignition sources
How to use
Before use, confirm that your brake system manufacturer specifies mineral oil. Follow the brake manufacturer's bleeding procedure and use appropriate tools and protective equipment. Open the container and pour or syringe the mineral oil into the reservoir or bleed port as directed, taking care to avoid contamination and to prevent spillage onto brake pads and rotors. Complete the bleeding sequence to remove air and ensure correct lever feel, then securely close reservoirs and properly dispose of any used fluid and contaminated materials in accordance with local regulations.
Usage recommendations
Use only in brake systems that explicitly require mineral oil. Avoid mixing with DOT fluids; mixing incompatible fluids can damage seals and compromise braking performance. Store the container tightly closed in a cool, dry place and keep out of reach of children. If fluid contacts skin or eyes, rinse immediately and seek medical advice if necessary. Follow manufacturer instructions for bleeding intervals and service procedures to maintain optimal brake function.
