Yesterday I dealt with a minor problem with the Harley, one that had been bugging me for a month or so. When applying the rear brake the stop light wasn’t coming on as quickly as I would like.
I was thinking that it might have something to do with the master cylinder rebuild I did some months back. That wasn’t merely convenience, it was a necessity! The pliable parts of the piston had largely disintegrated leaving the rear brake absolutely useless. The switch is actuated by hydraulic pressure so perhaps a bit of debris had made its way down the line and into the switch. Odd, since I completely purged the circuit and bled it thoroughly as part of the rebuild.
I noticed the trouble with the stop light during a pre-ride check so I bled the circuit again. The trouble cleared but soon returned. Another bleed, another temporary fix. This time when the trouble returned I did the electrical checks (all good) and gave in to replacing the switch.
So yesterday was the day. Luckily the local dealer had one for me and lightened my wallet by a twenty. I considered myself fortunate; they usually don’t have whatever part I happen to be looking for. Since it was my first visit to the dealer since they stocked the 2008 models I couldn’t resist browsing just a little…
Back in the garage, it took about fifteen minutes to replace the switch (with a metric wrench, so much for American Iron, eh?) and bleed the circuit yet again. The stop light was back to functioning normally at the lightest pedal touch.
I suppose I should have inspected the old switch to try to determine if it had any debris in it causing the trouble. But I just pitched it in the bin, grabbed a helmet, and went out for a test ride. Today they picked up the trash.
