Brakes Oil Heating Test
Cold weather can significantly affect oil performance, causing it to become thicker and harder to pump, adding strain to the starting unit and oil filter. A brake oil heater helps with easier starts by pumping warm oil to critical wear points. Laboratory tests are necessary to heat brake oil samples at extremely high temperatures to check their stability under stress. Download the application note and optimise brake oil testing under extreme conditions.
