How to replace the brake master cylinder in a two-mode hybrid on Cadillac Escalade ESV?

The Brake Master Cylinder replacement process for a two-mode hybrid vehicle requires you to turn off the ignition without stopping at accessory mode and wait 1 to 3 minutes while avoiding brake pedal use to let the brake modulator and hpa bleed pressure. When enough time has passed you should take brake fluid from the Brake Master Cylinder reservoir and place it in a permitted container. Unplug the Brake Fluid Level Sensor connector and easily detach the Brake Master Cylinder reservoir by disconnecting both return and supply hoses. Separate the primary brake pipe from the system by capping it while plugging the master cylinder outlet. Repeating this process, disconnect all brake brake pipe fittings on the left and right side including the front fittings. Then detach the Brake Master Cylinder by discarding and installing the new parts. Take off the Brake Master Cylinder nuts and throw them away. Afterwards pull out both the Brake Master Cylinder and master cylinder seal. Bleed the master cylinder before you put the master cylinder seal and master cylinder onto the adapter while making sure the seal bottoms out. Use 2 new Brake Master Cylinder nuts to fasten the unit at 33 nm (24 lb ft). Use a torque wrench to secure the left and right front brake pipe fittings, right supply brake pipe fitting, left supply brake pipe fitting, and primary brake pipe fitting to 30 nm (22 lb ft). Fasten back the Brake Master Cylinder reservoir return hose quick connect and supply hose quick connect accessory. Then secure the Brake Fluid Level Sensor electric plug. Add brake fluid to the master cylinder tank then perform a brake system hydraulic bleeding process.
