Rear brakelight switch repair

Post #1 by peteybug » Thu Aug 21, 2008 10:41 am

Got a new switch on e-bay cause mine went bad so decided to tear old one apart. Will never buy another. It's an easy fix! First take old one off bike. Then get some fine emery paper or sand paper. There is a small rubber boot at the top peal it back you will see two tabs. Now stand on end and push down on solid surface. This should push it apart.

Now pull it all the way out. You will see two brass or copper prongs and a shaft

Take sand paper or emery cloth an shine up the copper fingers and the ring on shaft you can use some contact cleaner if you have it. Now the one that I had the spring was shot so I took a spring from an ordinary pen and it fit right over shaft. In pic you will see two different units I did this for comparison.

Now just put switch back together and test with a meter or test light and should be good to go.

Thanks Cookie!! :oops: Like I said in one of my other posting's ( I hate things that can't be fixed) If I can use a hammer and screwdriver on it I might be able to fix it.

I was surprised when mine came back by spraying in contact cleaner but now that I see it apart there is no reson that won't fix a not too corroded one.

Nicely done... my rear switch is working but sticking "on" until I jiggle it so I was planning on cleaning it. Now I know what to expect. Good idea with the pen spring!

You also need to clean and lube your brake pedal pivot. Mine did the same thing before I cleaned the crud out of the pivot.

My rear brake peddal would'nt even move when I bought my 79, A lot of wd40 and a little propane torch to heat it with and some elbow grease moving it a little at a time and now the rear brakes work good as almost new :-D Also sprayed the switch with WD-40 and moved it back and forth and it works now too.

If you pedal is sticking in the slightest I would remove it and clean that pivot point properly and give it a coat of grease. It is a very easy job and does not take long at all. Disconnect the M/C, the Switch, and raise the pedal enought to relieve the spring pressure. Then remove the large cotter pin and slide the pedal off the shaft. I suspect you will find a lot of rust inside the pedal and on the shaft. Clean both of those up with some sand paper and grease it up then put it back together.

It doesnt stick at all anymore and operates really smooth but I am going to do a frame up restoration and slight customizing this winter. I will take step by step pics of the progress and keep them posted. This will be my first bike project and am looking forward to the challange :) I'm sure your and other NGW members advice and knowledge will be very helpful as it has been.
Thanks Rick
