First, briefly talk about the work of the brake cylinder
After stepping on the brake master cylinder to generate thrust, the hydraulic oil pressure is transmitted to the wheel cylinder, and the piston in the cylinder starts to move by the hydraulic oil pressure to push the brake pads;
As shown below：
Next, let’s explain the position and function of the Wheel Cylinder Lubricating greaseapplication：
1.Apply it between the rubber pad of the brake wheel cylinder and the metal
2.The effect of applying lubricating grease：
Anti-wear and anti-corrosion, prolong the service life of rubber！
The brake wheel cylinder lubricating grease must use high temperature resistant grease, because the heat of the brake cylinder may reach several hundred degrees when braking. Ordinary lubricating oil will melt and flow to the brake due to poor high temperature resistance. On the disc or brake disc, causing the brake to fail.
The following is the test report of the hydraulic brake system sealing grease used by our company, for your reference：
