Secure the vehicle on level ground and wear safety gloves and eye protection
Check the brake fluid type specified for the vehicle
Fill the master cylinder reservoir with fresh brake fluid to the proper level
If the master cylinder is new or replaced, bench bleed it before installation if possible
Install bleed tubes into the master cylinder outlet ports and route the tubes back into the reservoir
Submerge the tube ends in brake fluid inside the reservoir
Slowly depress the master cylinder piston or brake pedal
Release the piston or pedal slowly
Repeat the stroke until no air bubbles appear in the fluid returning through the tubes
Keep the reservoir filled during the process so it does not run dry
Tighten the outlet fittings or remove the bleed tubes after bleeding is complete
Reinstall the master cylinder on the vehicle if it was bench bled separately
Bleed the brake lines and wheels after the master cylinder is bled
Check the brake pedal feel for firmness
Inspect all fittings and connections for leaks
Top off the reservoir to the correct level and secure the cap
