How Do I Bleed My MTB Disc Brakes at Home?

A disc brake needs bleeding when the lever feels soft, spongy, or noticeably longer than it used to before the brake engages. This usually means air has entered the hydraulic system or the fluid has absorbed moisture over time. A home bleed replaces old or contaminated fluid with fresh fluid while removing trapped air, and is a manageable job with the right bleed kit, fresh fluid and a clean, unhurried workspace.
