abs keeps cutting in

[nottsgreent5]

abs keeps cutting in even when you just press the breaks slightly but after awhile its fine agen any ideas?

[nobananas]

Are you certain it's the abs cutting in and not brake judder caused by warped discs or knackered TCA bushes/balljoints ?

speed ring is either cracked or missing a tooth or 2. Just had mine fixed - same symptoms.

yeah certain its abs sounds like a machine gun every time i touch the breaks the lights come on and off all the time since i got the car 3 years ago but never caused any problems can the ring b changed on its own or is it a new hub

[Wobbly Dave]

needs a new end of CV joint

[nottsgreent5]

can the abs ring be changed on its own

[fireclown]

you can get them separately for some cars. but they are a pain to change. you need to heat them up. like a ring gear if you have ever done one of them. cv joints for the 850's are not to expensive. and probably not worth the hassle of changing the reluctor

[Wobbly Dave]

my new end cost about 60 quid.

have u checked to see if the rings are clean, if they have mud in them or a stop etc, they will do the exact same thing, i had this problem on my gsi i had a stone stuck in one of teeth causing abs to do that
