I need to know this about brakes do you fix front and back at same time?
Sure, but if you use brakes at all, then you're doing it wrong. When the green light or flag drops you hit the gas. Don't let off until you win the race or crash. Even if it's into a busload of drunken nuns.We usually do an axle --- in that we do both front or both rear brakes at the same time to make them operate in a balanced way so they don't pull and cause linear stability problems (accidental lane changes or running off the road or into a busload of nuns coming back from a wine-tasting day out from the nunnery).
