Techie question ... (Jeep)

[Mike Cecil]

Thanks for the replies.

Remember this was a new m/cylinder that was working fine since installation circa 2 years ago and before I replaced the switch, refilled and bled the system, so I doubt it has the wrong spring.

I've checked the brake pedal freeplay, lowered the fluid level in the cylinder, checked the tightness of the end bolt and changed the pressure switch yet again. No change. Press the pedal, and upon release, the brake lamp 'blips' off as the pedal recovers, but then remains on for a minute or so.

Can't think of what to do next. B****y annoying...
