Replaced brake fluid yesterday at 48K, not sure if it had ever been done. I had picked up a vacuum bleeder from Harbor Freight (Sale for $19, found cheaper on eBay). Opted to just use the adapter because of the nice bleeder connection.
Pneumatic Brake Fluid Bleeder Tool with 4 Master Cylinder Adapters 90 to 120 psi
Disconnected the ABS connector vs disconnecting battery. Bleeding order is different than RR, LR, RF, and LF. Followed FSM and did RR, LF, LR, and RF. End to end, a little over an hour to complete.
Pretty dirty, glad it is done. Pedal was good before, but is noticeably firmer.
