abs warning light

[penel]

the abs warning light is now staying on
i have done a few searches and it seems it could be a poor connection on one or more sensors possibly on the rears
is it possible that worn brake pads could cause this
has anyone else had this problem and if so what was the solution
last of all when you change the pads is there anything special that needs to be done or is it just straight forward job

thanks p

I had this light flash on and off when had very very worn pads. Had the pads changed, all sorted.

hello again penel if the light is staying on i would get your pads checked (is there any grinding when brakeing) changing pads can be fiddly and if you have not done it before you may have more bits left than when you started with if pads are ok and light still comes on a garage could probably sort it. sometimes they can plug into an diagnostic machine and do what i believe is similar to a computer re-boot.(redkev)

i had a look at the pads and it looks like around 5mm left on the rears but i cant see the fronts and there is a lip of about 1-2 mm on the edge of the discs

think i can handle changing the pads its just if there is a procedure for returning the pistons into the calipers without blowing any seals

thanks for the reply

all problems sorted now
fitted new discs and pads as discs were scored
abs light went out then returned a couple of days later doh
fitted new sensors to rear now alls good
