i have had a problem with my rear brake light kept flickering on and off all time, i have tracked the problem and it is the rear switch which appears to sit on top of a cylinder there was some corrosion on connectors which i cleared off but as soon as i reconnect the fault reoccurs so naturally i am thinking it switch but my problem is if i remove the switch will it have any effect on the cylinder it is attached to ? or is just a case of unscrew and screw on a replacement ?
cheers

the rear brake light switch is a brake fluid, pressure switch. Replacing it will open your rear brake hydraulic system. You might need to bleed the system after switch replacement. Switch cost $29. When you order the switch, be sure to order at least two banjo bolt washers too. I ordered eight banjo washers from bike bandit that took almost three weeks to arrive. The place I bought the switch from didn't have any washers. Well they had one. sort of. And all the local motorsickle shops didn't have any either. I've yet to replace the switch. (Chy and Greg noticed my rear brake light staying on all the time when we arrived in New Hampshire. Chy and Rob diagnosed it as both a bad rear brake light switch and a bad bulb. Thanks guys!  )

This is almost common enough for a recall, right after they do a CDI recall...

Yeah, in 2003. It was covered under warranty. I just unplugged it until I could get over to the dealer.

Not covered under warranty at Orange Park Power Sports (www.orangeparkps.com/suzuki). Brake light problems are the reuslt of installing Stebel horns! Who knew?

I had one go bad on my 04 Thruxton last summer. The switch was just a simple replacement. I didn't bleed the system and the brakes functioned fine. On the other hand I have no idea where the switch is on my America, on the Thruxton it's under a side cover mounted vertical so there is no mess.

moe is right, after investigation, the switch is not like the Thruxton switch which has no stud on it. You will need 2 new washers and need to bleed the system. Good luck.

Well, yesterday, after the rear brake switch checked out okay per a continuity check, I got on cinnamon girl and rode her a bit. So what it took me 9 weeks to get round to it.  While at a red light, I side-standed her, dismounted to the right and observed a brake light on. grrr. Went home let her cool a bit then using a 1/2" drive 22mm socket on the switch (the ratchet could not fully engage the socket -clearance issues) and an open end 3/4" wrench holding the brake fluid junction steady, broke the switch free. Real easy.
Easiest to work on the switch from the right side of the bike while the bike is on the sidestand not on a jack. Great angle of view and real easy to get it all cleaned up. Don't want any debris around when the switch comes off so the new one can go right back on. Two new oem sealing washers (banjo washers) and one new switch. Lost about 4 teaspoons of brake fluid. (1 tablespoon and 1 teaspoon). Did not have to bleed the system afterward either. Topped off the reservoir more due to worn linings than due to what dripped out. Can't really get a torque wrench on the switch (15Nm) but 15Nm is an easy feel.
Fixed the lectric issue with the lightbar too. Chafed hot wire right bucket.
Dropped a K&N filter in and pulled the snorkel. Great Sunday. Too bad it was 94 degrees.
130/42 3.5 no shims,no snorkel,single K&N,D&Ds
