MtotheJ Posted April 14, 2009 Posted April 14, 2009 Ive only just noticed that my brake light doesnt come on when the front brake is squeezed unless squeezed extremely tightly. Was just wondering if there is anyway to adjust the sensitivity of the light, in the way that it comes on when the brake is only lightly squeezed? The brakes are AJP on a gilera sc125/derbi gpr 125. Any help would be great!Thanks Quote

Stu Posted April 14, 2009 Posted April 14, 2009 it depends on the switch some release the switch when you pull the leave some push the switch when you pull the lever Quote
Pete Posted April 14, 2009 Posted April 14, 2009 I had exactly the same problem with my rear brake and had to change the switch which was a right sod on my bike but pretty straight forward on others! Luckily for you it's on the front which if I'm right lives in the vacinity of the lever (not behind any of the bike's frame like my rear one!) so should be easy to get at. It's full name is the front brake switch or sometimes the front brake sensor. I tried to find an image of one but couldn't, sorry! Try looking in a Haynes manual. If you don't have a Haynes manual go to Halfords or similar and buy one - they're invaluable and the amount you save by doing it yourself instead of paying some mechanic to take tea breaks on your watch means it'll pay for itself!!

MtotheJ Posted April 15, 2009 Author Posted April 15, 2009 Sorry for my ignorance but is the switch normally like a little pin towards the base of the lever on the inside? (will try to post a pic of it if i get the chance) Quote
Pete Posted April 15, 2009 Posted April 15, 2009 Just been having a look in my Haynes manual to see if can try and answer your last question but then thought better to take a copy out of the manual and post it up here (copyright)!However I've just realised from flicking through a few pages that the actual front brake light switch on my bike is situated on the underside of the master cylinder (metal cylindrical thing that brake lines go into, mine's aluminium), not inside the brake lever itself (that's just where the wiring connectors go). So, have a look between your front forks for the master cylinder and see if you can see the switch there. p.s. get a Haynes manual today, you'll love it!! Quote
MtotheJ Posted April 15, 2009 Author Posted April 15, 2009 Thanks sp will have a look! Is there a general manual just for all bikes with basic stuff in? as there isnt one specifically for mine Quote
Pete Posted April 15, 2009 Posted April 15, 2009 Oh bum I see what you mean! A mate of mine had the same problem with a Honda Accord VTEC Type R car where they only produce a Haynes manual for the standard Accord. In the end he found an "official" service manual on ebay which was a disk that he got sent in the post. It's great because all you need to do is take your laptop out with you and work off that (with cling film over the keyboard!).Try searching on google for a service manual for your bike, or even try contacting Gilera to see what they say. There will definately be some sort of manual somewhere, even if it's not a Haynes one. Quote
