Can Brake Fluid and Hydraulic Oil Be Used Interchangeably?
1 Answers
Brake fluid and hydraulic oil cannot be used interchangeably. Below are the specific differences between brake fluid and hydraulic oil: 1. Different functions: Hydraulic oil plays roles in the hydraulic system such as energy transmission, wear resistance, system lubrication, corrosion prevention, rust prevention, and cooling. Brake fluid ensures that the vehicle can effectively and reliably maintain flexible braking under various operating conditions, including severe winter and summer temperatures, high speeds, heavy loads, high power, and frequent braking. 2. Different compositions: Brake fluid can be castor oil-alcohol type, made from refined castor oil plus ethanol or butanol; synthetic oil type, composed of ethers, alcohols, esters, and additives; or mineral oil type, made from refined diesel distillates plus thickeners and antioxidant additives. The appropriate type should be selected based on specific driving conditions. Hydraulic oil mainly consists of plant-based base oils and synthetic esters.
