There is a wide variety of cooking oils from plant sources such as olive oil, palm oil, soybean oil, canola oil (rapeseed oil), corn oil, peanut oil and other vegetable oils, as well as animal-based oils like butter and lard.
We called a couple of the brake fluid companies and the answer was two to five years is a safe number for an unopened container. Wilwoodâs tech line claims that if the container is sealed, they feel it has an unlimited shelf life, but I would consider five years to be the limit.
Updated: 05/12/2009 - by Mac Demere, Contributor. I've made brakes last more than 90,000 miles on my personal vehicle and, as a racecar driver in 24-hour events, kept brakes alive for hours. In other races, I burned the pads almost down to the backing plate in fewer than 50 miles. That was perfect. The events were but 40 miles long.
