Right then, i have just taken my calipers off and painted them. Left them to dry and re assembled. Left the car standing for at least 2 hours after it was put back together. I have just gone out to move it and the abs light is on constant and the braking is not very good. Any ideas what it could be? Its kinda urgent too as im doing a 150mile trip tmrw morning!

stevenet15 · 14th March 2007, 14:45

when u say taken the calipers off do u mean u took them off the car or jsut off the hub? are any of the calbes twisted and did u knock the abs sensor?

yerdusk · 14th March 2007, 14:52

jus took them off the hub and suported them. They are def not twisted, but i dont know what you mean by abs sensor! Where abouts is this?

stevenet15 · 14th March 2007, 14:57

i presume u have abs on your vtr as u put "abs light is on" the abs sensors are on the wheel hub and face the drive shaft where it takes a reading from groves off the driveshaft as it rotates. could u have split or dripped an paint on it?

stevenet15 · 14th March 2007, 14:59

sensors look like this

yerdusk · 14th March 2007, 15:09

right, maybe i could of knocked it, as i placed the caliper on top of the disk to dry, and i could of hit it i suppose. is this a major problem? i have just been for a drive and the abs is not working, under some hard braking it skidded like hell!

check the passenger side caliepr and pads etc.. and make sure its all in place as if u brake hard enough they should both lock up, you can test the abs sensor by disconnecting the plug with the sensor still on and connect a multimeter to it and then spin the wheel, u should get a change on the screen e.g 0 - 1 - 0 - 1 - 0 - 1 where the sensor is picking the notches up off the driveshaft. if its not picking them up then its the sensor. as longs as the brakes are on correctly for definate then it will be ok to drive but u will have to be cautious as the abs wont be working so it will be like drivein a vtr without abs.

ok mate thanks. I will go and have a look in a mo. Are these sensors expensive to buy, and easy to fit?

right mate, i have just been out and checked. Everything is on as it should be and the sensors look fine. I didnt even go near them, they are a little dirty but thats it. Any other ideas? also, i take it this will fail mot if abs not working?

stevenet15 · 14th March 2007, 16:03

clean them off if there dirty as it could b stopping them from getting a signal off the shaft. i gtg to the gfs now but i'll try check this thread later when i get back

yerdusk · 14th March 2007, 16:05

ok mate, will try that. thanks mate, rep left

yerdusk · 14th March 2007, 17:26

UPDATE!
Right. I have just been out and undone the sensors, and they were really shitted up. So I have cleaned them gently with a nylon brush and they came up pretty good. Done it on both sides. And guess what, still abs light on and no abs on car! Please help me!
