Replacement of a brake light switch
I had a hesitancy to replace the brake light switch on my 1989 td Defender.
After correcting some wiring issues, cleaning all the grounding points in the system, I was able to get the brake lights operating by using a jumper wire across the terminals. So, isolating the final problem to the switch, I replaced it.
The old switch came out without having to remove the brake master cylinder and booster unit. I did not have to loosen and remove the brake pedal tower. By working at the top of the tower, right up against the firewall, and its cutout/relief, the new switch went in. A slight adjustment for the 5mm pedal stroke to illuminate the brake lights - and I was done.
Total time for this switch replacement was 25 minutes. As I do not have a garage and it was 28F here in Santa Fe, I am pleased that it did not take longer.
