ABS coming on every time when below 5mph and coming to a stop

[hazkirby]

When coming to a stand still ( below 5mpg) the brake pedal will kick back at me no matter what the road condition is like.

The brake fluid was changed yesterday, and the drivers side drive shaft was also changed, so I'm guessing it is to do with this?

Any help would be appreciated!

Cheers

ABS ring related, is it a genuine shaft?

 

[Daniel]

I'd imagine they cracked an ABS ring when fitting the drive shaft.

If it wasn't like it before you had it fitted, take it back to the garage who did it.

Nope new but.not genuine. Need to replace?

I wasn't aware you could get non-gen driveshafts for 172/182s??

ABS sensor isnt reading, the reasons for this are often that its a wiring issue with the sensor, when they undid the hub and moved it they may have put some strain on it and as they are old and rotten they can fail, or as above the ABS ring was damaged or replaced with the wrong type.

Some rubbish driveshafts have a narrower abs ring, and doesn't pick up the signal correctly.

Strange, Would of thought the abs light Would come on if the abs ring is cracked.

As Daniel said just take it back to who ever fitted it and get them to sort it.

Incorrect amount of teeth on the driveshaft? Did a garage change it? If so don't they check there work?!?

 

[Chip-mk1]

Wont be incorrect number I wouldnt think, but the different models have different profile rings.

If its just the sensor has stopped working from being disturbed then he will need to buy a new one, its not the garage fault if the sensor wiring is old and rotten and doesnt like being disturbed, happens quite often.

 

[scotty2hotty81]

If it was a sensor the abs light would be on, when your order a replacement ring through (jr) a company that sell on eBay they ask you to specify how many teeth, just a thought as if one wheel has 43 teeth and the rest 44 the abs will be confused into thinking that a wheel is skidding, just the same as when the rings crack it opens up and in theory adds another tooth, either way its clearly to do with the side that has had the shaft and should be simple enough to find.

 

[Chip-mk1]

No the light doesnt always come on when its the sensor, ive had them where the ABS takes the pedal away from you but the light doesnt come on when its been a faulty sensor.
The light comes on eventually, but not always straight away.

 

[Tony Hunter]

Anyway.

Take it back.

Hi

Thanks for the responses.

I bought the driveshaft new from jr as here http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=130613528995&ssPageName=ADME:X:RTQ:GB:1123 and had a mechanic friend fit it.

Also after further testing I turned the abs off and still get the same issue.. if it there was a difference in the amount of teeth then I'd feel the issue all the time, not just when I'm doing < 5MPH..

Tested emergency braking from 40MPH to 0 and the car stops really well, until about 3MPH when I can feel it 'slipping'.. very strange.

Of course I didn't turn the ABS off... can't do that can I duhhhhhh

My moneys on a cracked ABS ring. Mine started doing it and I noticed one of the front rings had a lovely crack in it. Never bothered fixing it, just made do.

Pull the abs fuse, see what it does then.

you can buy them. they're wrong and start vibrating and knocking after about a week, as they're the wrong length
