The time needed for a brake job varies depending on the specific work required and how busy the shop is.
Here's what you can expect:
A simple brake pad replacement is usually the quickest fix, often taking about an hour per axle (two wheels). If your rotors need work, the brake job can take longer, potentially a few hours.
Major repairs involving brake lines, calipers, or the master cylinder can take significantly longer, sometimes requiring most of a workday.
