MG Car Repair: 66 MGB Brake Light Switch, brake light switch, bleeding brakes

Question
Noticed my brake lights weren't working, since it was both, thought switch as first check. Located switch, if I pull wires and connect brake lights come on. Assume that's a pretty solid way to identify a failed switch.

Replacements are readily available. But I've yet to locate a walk through on RnR the switch. Can it be as simple as unscrewing and screwing in the replacement? What about bleeding brakes or pipes afterwards? Can the switch be replaced without introducing air into the brake system?


Answer
Hi Rob,
You can change the switch without getting air in the system if you unscrew the switch and put the other in quickly usually by holding the new switch in one hand and removing the other with the other hand you should be able to quickly change switches without much loss of fluid and without getting air in the system.
