Abs kicking in

[mad in general]

Today I have felt a bit of a flutter through my brake pedal when on rough ground at low speed. I was approaching a zebra crossing on the high grip surface and tried to slow for some pedestrians. I went right through it with the pedal pulsating.

No warning lights on the dash and on smooth ground the brakes work perfectly.

​any ideas?

Low tyre pressure/puncture in one tyre

Cracked ring or a lose sensor.

Would low pad level cause it? Not had the chance to get the wheels off.

 

[Toby]

Probably what tony said.

Sensor would be my guess though.

This! Get it looked at before you actually plough into someone.

On the drive home the abs light and Serv light came on.

I have no abs and the brakes are working fine. I will be looking at it in the morning.

Just like what tony said, my clio was doing the exact same. my problem was a snapped reluctor ring.

Crack in the abs ring just bought one for my own car this week

Ok the front passenger abs sensor wire is broken. Snapped right where it goes into the sensor.

Where do I get a replacement, what sort of price and how do I replace it???

​Cheers

They can be an absolute bugger to remove. Can be quicker wanging a new hub on it ime

If I totally disconnect the broken sensor will it affect anything apart from the lack of abs? Just thinking I may as well try removing it before buying a new one.

If I have to replace the hub, what sort of price would I be looking at and what does it come with/do I need?

 

[Djw John]

No it would stay just the same as it is now.

2nd hand hubs don't cost much, circa £20 from memory. Being a ph2 you have the same bolt spacing as ph1, all ph2 and non cup 182s which should make it easier to find one. Just get one with a working abs sensor and preferably a bearing but don't stress about the bearing too much.

Well that's tomorrows task sorted.

Do you have any tips for removing the abs sensor? I have read a post from Fred which suggested they don't come out without damage but obviously not bothered about that as if it does come out then im replacing it.

Cheers

 

[MicKPM]

I find silicone spray helps but getting them out intact is as much luck as it is a skill.

 

[Djw John]

Agreed!

 

[Tony Hunter]

Last time I did one, it was a hammer and screwdriver job!!

 

[mad in general]

And if it does break, is it easy enough to remove the rest?

 

[Tony Hunter]

You might end up drilling the screw out, never had one come out yet.

Do you mean the torx bolt?

 

[Tony Hunter]

Yes.

 

[mad in general]

well well well,

The bolt came out pretty easy actually. Will the sensor budge? nope!

I have smashed it up with a hammer and various screwdrivers, the majority of the sensor is removed. However, the bottom section appears to have to come out the underside between the abs ring and the hub. Is this correct? how do I remove the rest? Im now in a position where the bottom half of the sensor is right up against the abs ring and I cannot rotate the wheel.

Do I need the hub off to get the sensor out?

 

[Djw John]

Yup

 

[Tony Hunter]

They are an absolute arse to do.

 

[mad in general]

Done, Hub off and 16mm drill bit cleaned it out nicely. Anyone know what sort of price for a new sensor is? Or does anyone have a working one for sale?

 

[Djw John]

Good stuff. New is gonna be the only way really, give Adam at Wolverhampton Renault a ring.

 

[mad in general]

Think that's what I will be doing.

Cheers for the help guys!

 

[Djw John]

No worries, I'll pop up for a 4 pack of my choice (I work in the royal ed )

Ah! Never knew that.
Have you been in before?

 

[Djw John]

Not for a long time, just slightly further than I can manage comfortably in my break, next time I go to the rbs I'll pop over.

 

[mad in general]

I see, We have had the place for 5 years now so maybe saw you before.

Feel free to do that mate, put a face to the name.

Hello again,

Still not bought a new sensor yet. I went to Unipart and they quoted £54 +vat for a bosch one. Part number BSH0265006383.

Can anyone advise me if this is the correct sensor and if its a good price?
