• Be careful not to over-tighten the bleed nipple. Over-tightening can damage the threads and make it difficult to bleed the brakes in the future.
• Use a clean rag or towel to wipe away any excess brake fluid. Brake fluid can be corrosive and can damage paint and other surfaces.
• Be patient. Bleeding brakes can take some time, but it is important to be patient and not rush the process. Rushing can introduce air bubbles into the system, which will require you to start over.

Please ensure you use the correct brake oil. If unsure check with your bicycle's manufacturer. Mixing or using the incorrect oil will more than likely damage your bikes brake system. Ensure the hydraulic fluid does not make contact with the bikes brake pads or disc brakes. If it does then the brakes performance will reduce. Should the fluid make contact with these components we recommend changing them. Before proceeding with bleeding your bicycles brakes read and understand the hydraulic fluids safety and handling instructions. Know what to do should the fluid make contact with your eyes. We recommend wearing rubber gloves when using this brake bleed kit for bicycles. Bleeding your own brakes is an easy task. However if you are unsure we recommend taking your bike into a professional service center.
