How do I bleed Shimano MT400 hydraulic brakes?

Use Shimano's bleed funnel and syringe kit with Shimano Mineral Oil. The process takes 15–20 minutes per brake and is well documented in Shimano's service manuals. Professional bleed recommended for first-timers.

What rotor size should I use with the BR-MT420?

The BR-MT420 is compatible with 160mm and 180mm rotors with appropriate adapter. 160mm is standard for XC; 180mm is recommended for heavier trail and enduro use.

How long do brake pads last?

Typically 500–1,500 km depending on terrain, rider weight, and conditions. Inspect pads every 3–4 months; replace when material reaches 0.5mm remaining thickness.
