Replacement Guide
Interval, Specs & Step‑by‑Step Process
Brake fluid is highly hygroscopic – it absorbs moisture over time. Contaminated fluid has a lower boiling point, which can cause vapor lock at high temperatures and lead to brake failure. Regular replacement is non‑negotiable.

💡 Bleeding reminder: Pull lever → hold → open bleed nipple → close nipple → release lever. Repeat until fluid runs clear and bubble‑free. Never let the reservoir run dry during bleeding.
Fresh brake fluid = firm lever, consistent bite, and safe stops. Replace it on schedule, and your brakes will always be ready when you need them most.
