ABS noises at almost stop. Rubbing sound at R turns

[oze30]

My ABS makes funny noises and the pedal travels back up when slowing to a stop ( usually occurs below 10-15 mph)

Any ideas? I changed the front legs, and the sensor wheel was a bit rusty. but my abs light has now gone out!! Anyone?

And also on a right turn, there is a strange metalic rubbing/grinding noise. Ive checked the dust shield, and it's clear of the disc. Could this just be the rust again?

How hard is it to change front hubs?

update, It (the abs) comes and goes. but when it's working, the pedal springs back up.

Anybody??

Bump? I've tried search, but nothing

Warped Discs or wheel bearing maybe??

I'd say the ABS unit has gone up the wall
Metalic rubbing sound, i would say that the dust cover is still touching the disc. The ball joint has probably got a bit of play thus allowing enough movement for the dust cover to touch the disc.

Ive checked all that. Ball joints are new (as are whole lower arms.) ABS unit.. you mean the ecu or the pump?

anyone??

I had mostly the same symptoms as this and it was a faulty abs sensor at the wheel that sounded funny and seemed to have rubbing sounds.

The exact symptom - at very low speeds while applying the brakes the abs seemed to cut in and I felt a slight pulse through the pedal. The abs warning light didn't come on until the fault had been apparent for months. It felt almost as if the brake pads were almost completely worn out and that I was hitting a patch of ice on the offending (front offside whee).
I established it was definately the abs sensor at the wheel by using some special computer gadget at a mate's garage.

If you can estimate which wheel it is you could try swapping it.

At first (as it was cheaper) I just got a local garage to change the pads and asked them to check the sensors too. They didn't work out the problem and recommended I take it to a BMW garage! Twats! AMazing how poorly equiped the backstreet garages are - they can't even test a fifteen year old system!

I think you could test each wheel sensor with a multimeter and checking resistance but don't quote me on this. Also if you don't have a mulitmeter this is no help. The wheel sensor cost about Ԛ£70.

Hope this helps

Did you sort this one?

If a wheel bearing has gone, the ABS isn't going to work properly.

Did you sort this one?

Not yet. got 2 new bearings and sensors waiting to go in

no expense spared then
