The main features of the rubber diaphragm
1. The rubber diaphragm in the master cylinder and the wheel cylinder must have certain elasticity and compression deformation and wear resistance to ensure that the rubber diaphragm has a certain returning capacity and sealing ability to transmit hydraulic pressure during use.
2. It is resistant to hydraulic medium at high temperature (100~120°C and low temperature (-30~50°C). The rubber diaphragm is in contact with the brake fluid for a long time in the brake seal device, so it is required to brake fluid ( Liquid, mineral oil) has good anti-swelling properties and does not allow leakage at high temperature, low temperature and static room temperature
