How do you remove the front brake light switch from the master cylinder? I did read that someone said the was a small hole under the lead, but I cannot find one on mine (sx650sh), imported from the USA.
I had a revelation the other day. I've been fighting with those OEM type leads since I got my 1981 last winter when I was trying to remove one from the old OEM MC. I thought until this Tuesday, how in the h could this be so hard. These bikes are old and have been laid on their side multiple times. The lever housing gets knocked out of round jamming the lead in and making it hard to get a new one in.How do you remove the front brake light switch from the master cylinder?

On the MC body there's a hole under where the wire enters, the plastic end of the wire lead has a tab that catches the edge in the hole, pressing in with any suitable probe releases the lea

On Tuesday I was was trying to install a new switch on a master cylinder from a 2014 v star 250 . I got the MC on ebay for 22$ and it is a real nice NISSIN 12.7mm.Yes, in a perfect world, all you have to is you press up on the hole at the bottom of the hole you stick the sensor. The hole seemed to small.
The V star must have been dropped and the hole was knocked out of round. So on Wednesday I finally figured this out.
Stuck the master cylinder in the bench vise and took a big threaded bolt of the type I used to clamp heavy pine boards on a fence gate to the post cemented in to the ground. I screwed it in and pushed the aluminum out again.
Be careful and don't go to far in. I should have used a torch and heated it up first. I cracked the aluminum a bit, but thats O.K. it worked out anyway. The lead slipped right in and holds.

Yes, it is.Thanks 5twins. Found it underneath, next to the word NISSAN 14. Is a Nissan m/c standard.
A new or used 11 mm bore (max 12 mm) Brembo or OEM Yamaha from a newer model would be my recommendation. Just make sure you get one with a brake light switch.Thanks all, after some perseverance and a lot of flushing with wd40 the lead/cable finally gave up.
Now to remove the rest.
I've been looking on evil bay and see that I can buy a pair of Chinese levers for less than a m/cylinder repair kit. Am I mad by repairing the old one or not?
the chinese $20 12.7 worked well until 500 miles later when lever spring came out.Thanks all, after some perseverance and a lot of flushing with wd40 the lead/cable finally gave up.

Yes, OEM Yamaha do have the LH mirror thread. But I do not believe Brembo are inferior in any way. Rather the opposite.....Both of mine are from other old Yamaha models. I chose them because they accept the original brake light switch, lever, and have the reverse thread mirror mount. Yamaha quality was a consideration as well.
The Chinese levers have arrived (very quickly). I still have another question, I bought the stainless steel banjo bolts from a UK seller, and I notice that the holes for the fluid to pass through are smaller than the Chinese or the Yamaha originals. Does this matter?the chinese $20 12.7 worked well until 500 miles later when lever spring came out.
Forgot to add that there is not any size of the bore on the master cylinder.The Chinese levers have arrived (very quickly).

If lever travel is from extended all the way to the grip to apply the brake, the bore is too small. If there is no lever travel to apply the brake, the bore is too big.Forgot to add that there is not any size of the bore on the master cylinder.
