To bleed the brakes on a 1992 Roadmaster with Bosch ABS, start by ensuring the master cylinder is filled with the appropriate brake fluid. Use a scan tool to activate the ABS pump, as it helps to push fluid through the system.

Make sure to check fluid levels frequently and repeat the process until you achieve a firm pedal.
