The equipment needed to bleed hydraulic mountain bike brakes differs slightly from model to model but regardless of which brake you're trying to bleed you will usually need the following:

• Bleed Kit - containing syringes, bleed adaptors, how-to instructions
• Brake Fluid - DOT or Mineral Oil, depending on your brake model
• Bleed Block - to keep the caliper pistons in the reset position during the bleed process
• Basic Tools - for removing bleed port screws, brake pads and adjusting the position of your brake lever or caliper
• Protective equipment and paper towels - brake fluid can be nasty stuff. Keeping it off your hands and out of your eyes is always a good idea
