Rear Brake Light Switch

[redmandan]

Can’t help too much with the electrical question but I did a rear calliper rebuild not too long ago. You can change the seals without breaking the Caliper apart. I think I read somewhere that you can’t get new caliper seals anyway so it’s best not to break it. For the piston seals get only genuine Yamaha ones, even though they seem expensive for what is essentially 4 pieces of rubber. Aftermarket seals are a bit hit and miss with fitment.
