Features: 1. LOW-RESISTANCE OIL INJECTOR: Using high-quality materials, with high resistance, high chemical resistance, high fracture elongation, good impact resistance. Even when the high-consistency suspension oil is promoted, it can have considerable smoothness and will not decline due to long-term use. 2. OIL FILLING BOTTLE: Fully transparent oil bottle, clear at a glance, used to collect old oil or empty the brake handle. The hose buckle can reinforce the hose and is not easy to slip off. It is specially designed for the oil discharge screw. The metal hook can be bent by hand to adjust the shape of the hook to make it more compact. The rubber band can reinforce the oil bottle and make it firmly fixed on the car body. 3. POSITIONING BLOCK GROUP: Used to position the piston during the oil filling process to prevent the piston from moving. It can be matched with the piston block for fixing the film. 4. TOOLS: 7MM open end wrench for tightening the oil unloading screw; 8MM open end wrench for the disassembly and assembly of the brake hose screw; T10-T15 star wrench-for the disassembly and assembly of some brake handle oiling screws . 5. INNOVATIVE OIL CHANGE METHOD: Through repeated push and pull operations on the caliper, an open oil reservoir oil bottle or funnel is set on the brake lever, so that the oil bag is completely free from force, allowing the air to be quickly discharged and enter the reservoir Oiler and needle inside. It is more efficient, easy to operate, and not easy to damage the brake. Notice: Actual color may be slightly different from the image due to different monitor and light effect.
