Getting ready to do this this afternoon. Had a basic question about draining the brake fluid before taking the caliper off to replace it with the new one. Is the fluid better drained through the valve on the caliper by attaching a hose and squeezing the brake lever, or is it better to drain through the master cylinder line that goes into the caliper, and just let it drop into a container? I was thinking a little of both, starting with the valve, as since its under pressure, the fluid may spray out if I unscrew the banjo bolt first and pull the line off that way. Thanks.
