brake light

[TIME LORD]

Could any one help please,

my brake light had blown only the part when i press the brake but the light comes on as normal with the head light.

I have replaced the bulb but the brake light when pressed still does not come on.

Have you tried your brake light with your rear brake only (foot)?
If this works, it could just be the switch/sensor for the front brake lever.
I had a problem with mine (it just wears out!) £6 ish from BSA (MZ parts)
Really simple to fix!
If your brake light dosn't work on the rear then I don't know.

[TIME LORD]

thanks for the info,

I did try the frount and back on the lever and the foot pedal and the light did not come on with the lights turned off, but with the lights on it does come on but does not get brighter when the pedal or leaver is used.

I would like to say thanks for your help and give some more part numbers.

Yamaha Part

This number on the packet 5JH-H3980-02 and F20060830.
from web site www.beedspeed.com [A] 24 614 0030 & [A] 24 614 0040

This one comes with a wire attached and a cover but you can take them off and the switch is the same as the original SM part.

Gilera, Piaggio, Vespa parts

Part number [A]-24 614 0010 this is a metal one but it still fits.

I am still looking to get the back switch.

Sorry Dave, I was not saying yours did not fit but I could nt find a dealer that had some in the shop and was trying to be of help to others with more part numbers.

[DAVID THOMPSON]

I have got the switch for the sm but was woundering how to fit it I can unscrew it but how do i get the brake line off with the ring.

Please see picture

I find it hard to believe that both switches could be bad.
Have you checked that your replacement bulb is twin filament (sometimes the simple things)

[TIME LORD]

I have never replaced the back one in six years but the front one i have had at least one a year.

But could any one help with fitting the back.

[DAVID THOMPSON]

on my rt the switch is also the bolt that holds the line on
remove switch and line comes loose then replace

and have a ton of fun getting it bleed of air after done yuk

[TIME LORD]

Thanks Dave,

So the the brass washer may be squashed to much and binding it up they must have over done it in the factory as i have never changed it before.

Thansks again Dave your a Star.
