Galaxy 99 - Abs Light On - Severve Brake Judder

[Metalliblob]

Hi Everyone,

I really hope you can help.

I am new to the Galaxy and have just purchased a 1999 2.3i .

Its had all the usual problems, handbrake cables rotted etc but I have a problem I cannot sort out.

The drivers front wheel brakes judder at low or high speeds its so severe that I cannot drive the car for fear of comming off the road.

It happens about 99% of the time you touch the brake pedal.

The ABS light is on.

I have replaced the drop links (both sides) bottom ball joints and have looked at the discs but they seem ok. It seems more than that.

The ABS rings are intact, perhaps a little dirty.

The drivers front tyre is scrubbed on inside edge.

Can anyone think of anything else to check out?

Thanks in advance,

Rik

Hi Metalliblob,

Welcome to the forum,

Seems like your tracking is toe out making bumpy roads and fast corners very scary

check your wishbone rubber and top of mcpherson's strut for excessive movement

my guess by changing the balljoint and droplinks its knocked the traking out worse than it was

my local tire shop charges

Hi Cyborg,

Thanks for the info, I'll get the tracking checked out.

Top of the struts sounds like a fun job, I'll have a look at it tomorrow. Might as well replace the rubbers while their off.

 

Any ideas why the ABS light is staying on? Is there a way of testing the sensor to see if its working?

Thanks again,

Rik

no worries we all help,

Worth doing a visual check first checking for broken wires or use your favourite scanner to show which sensor has failed ,

most on here use vagcom to detect faulty sensor and clear fault after repair. The sensors rust and expand oftain need drilling

out not to expensive about

Thanks for that. I'll get the multimeter on it tomorrow and see whats going on.

I really appreciate your help.

Got an update on the situation.

Checked the front ABS sensors with the meter. got a fluctuating signal from n/s which is correct, o/s got nothing.

Look to have a dodgy sensor on the front o/s wheel, so will replace once off. See what you mean about rusting on, going to be one of those jobs that should take 5 mins but with all the prep it will probably take a couple of hours. Oh well.

I have replaced the strut tops as recommended, the old ones were a little perished.

 

The brake disc's appear to have a slight warp in them so they have been changed. This job is clocking up to

I know its late but I have another update.

 

After fitting new sensors I found that one of the plugs on the inner wing was corroded which was the reason for the light not going out after the sensor change.

Cleaned and sorted. Drove upto 20mph abs light off, brakes not vibrating and it stops!

Thanks for all you help all good now.
