Align the gaps in the adjuster and lock ring

 

Pull back on the housing and guide the cable through the opening

 

Remove the cable head from the cradle on the lever blade

 

Disconnect the motor cut off cable

 

 

Loosen the 32mm hex/allen pinch bolt and remove grip

 

Loosen the 5mm hex/allen pinch bolt and remove the brake lever

 

Now you can work backwards to install the new brake lever.
