Morris Minor Owners Club

Having passed its MOT the 4door has now decided not to show brake lights !.

Connecting the two wires makes the circuit and the lights glow properly.

I presume it makes no difference which grub screw hole the wires go to ? ( the +ve feed being isolated in the switch (?? is that the failure on this unit ?) to the -ve earth that this car enjoys )

I presume when pedal pressure applied some kind of metalic connection is made from the T piece to the two brass connectors , making the circuit, which seems difficult to see how the unit can actually fail !

I note that brake pedal pressure is also spongy , becoming harder as depressed a few times - new cylinders have recently been fitted all round, but might not have been bled correctly ?

New switch required - see many other posts on the subject - there are some rubbish switches out there.

Brake pressure switch has failed, a common problem.
The braking system often benifits from a second bleeding session

The new switches dont seem to be the nice brass finish.

I am thinking, that given the slight spongy on the pedal , unscrew, check switch off car , refit if OK , then bleed through again.
(from memory start bleeding from the longest runs ( or as best as possible on the rears ) , then the fronts )

Nice new DOT4 fluid

I'll report back when done.
