Factors affecting time:
* Experience: A seasoned mechanic familiar with the vehicle will be much faster than a novice.
* Accessibility: Rust, seized bolts, or other mechanical issues can significantly increase the time required.
* Tool availability: Having the right tools readily available will speed up the process.
* Bleeding the brakes: This is a crucial step that can take a considerable amount of time, especially if you're doing it alone.
A reasonable estimate for someone with some mechanical experience would be 2 hours, assuming no major unforeseen complications. However, be prepared for it to take longer. It's always best to allocate more time than you think you'll need.
