BMW 325

How do I go about replacing the brake master cylinder kit
on my BMW 325I.1990 modle with 230 000 km on the clock.

Assuming you have the replacement part already in hand, remove the fluid reservoir, then the brake lines, then the two bolts holding the master cylinder to the booster.
Inspect inside the booster for brake fluid. If fluid is present replace the booster. Reinstall new part and bleed system
