Warning: Over-stroking the BRAKE master cylinder may cause it to fail.
This can happen to even the most experienced mechanic, "Especially" on a high mileage car.
The old school manual brake pedal "down" - "up" - "down" - "up" bleed method risks over-stroking the master cylinder.
The master cylinder piston seals can get scored if they're pushed into a normally unused - corroded, region of the master cylinder's bore.
If this happens, you'll have little or no brake pedal, and will need a new master cylinder.
I strongly recommend using a pressure bleeder or put a wood block under the pedal to avoid the issue.
My most recent personal experience Over-stroking the master cylinder.
