Brake Pad Sensor Broken?

sam2909 · 11th January 2015, 17:53

Hi,

Taken the drivers front wheel off today to attempt to replace a suspected broken abs sensor (speedo dead and ABS Light permanently on) and noticed the brake pad sensor hanging out the hole and doesnt seem to want to click back in?

The strange thing is there is no Brake Pad warning light on the dash even though the circuit is clearly broken! Just ABS Light which I presume is completely unconnected seeing as the speedo is dead?

Obviously I am going to order a new brake pad sensor now as well but can anyone explain why I have no light on dash?

The brake sensor is still intact (making a complete circuit) and should press back into the recess. The ABS sensor may be just loose, try pulling the connector apart and re-fitting, pushing it fully home.

Not worn, as posted above.

A wire runs into the sensor and out again.
This wire breaks ( Wears away.) When the pads are worn and the sensor touches the disc.
The break in the circuit puts on the warning light.

The sensor is held in by a tiny spring clip which is VERY easily lost.
If the sensor is out the clip has probably vanished too.

Click the pic Sam.

The sensor is the size of a pea on one side only, and clips in with a metal spring that is smaller than a pea!

thanks for that pic colvert - understand now!

How do I get hold of a new clip? Does it come with the sensor if I get one off ebay or the like?
