I'm putting a new set of grips on and want to try my best as to NOT damage the brake switch sensor. a few dealers I spoke (all) said that more than 50% of the DIY installs result in breaking the switch? do I squeeze the lever an put in a 1/8"(approx) shim before I remove the whole assembly? who's been there and done that? - thanks

 

good thread.... I also would like to know..... Bump for knowledge.

 

Just did this with handlebar install. Pull in on brake lever and stick a wire tie (loop end) into gap where lever would rest against perch. Lever will stay somewhat pulled in and you're good to go.

 

when screws are out move lever side of assbly straight towards mirror, correct?

 

Yes. Pull towards mirror and slightly to left if your facing master cylinder from front of bike. The micro switch is located in the lower section of switch handle and will be visible as you start removing master cylinder. Shouldn't have any problems as long as you keep wire tie in lever.

 

Correction...pull slightly to right as looking at master cylinder. Getting left right backwards. Lmao.

 

OK been there done that. I use a rubber garden hose washer that you can place in the opening created when squeezing the baker lever. Tried cardboard and had is slip out the rubber washer will slip.

Good luck.

 

Is this what you are referring to?? Words do not help near as much as a photo does.
Is this what you are calling the "perch". Do not understand that terminology.


The circle shows where the wire tie is inserted.

 

wire tie ( fastener end) works great- use a brightly coloured one if you can, so you don;t forget.

Mine is hot pink

if doing a bar swap and you need to rotate the brakeline- leave this is place as it gives a slight positive pressure to keep air out of the lines.
You will need a catch rag!
lightly loosen the 12mm bolt and ease the line to desired location. snug bolt

Just slide a piece of corn flake box card board in there after you squeeze lever. Strip about 3/8 wide about 4" long. Before you do it, squeeze lever and with a small light, look back in there and you will see the small black rubber boot on the micro switch you are protecting. If you are careful and insert lever like something will break, you will be fine. What gets most in trouble is acting like a 16 year old's first time. The boot on this switch is torn off.
