Easier And More Technology A more scientific and easy way to change oil for all brakes. A more scientific and easy way to change oil for all brakes. Two Kinds Of Oil Storage There are two kinds of oil storage: filling cylinder and funnel, which can handle the brake handle of any structure flexibly. Can be used to collect used oil when the bottle is tied to the caliper Ten Different Connectors Ten special connectors plus a multi-function connector, which can be connected to the filling bottle or syringe High Stability Fuel Injector Chemically stable low resistivity injector can provide objective flexibility even when pushing high consistency shock absorber without deteriorating from prolonged use Caution To ensure that the purity of the oil circuit is much more important than draining, it is recommended to use an oil bottle as a brake. (Although the capacity of each brake is approximately 20ml, it takes at least 1-2 times the amount needed to clean the oil circuit.) Compare with similar items Product description Features: 1.
