How To Check Is Abs Sensors Are Working

[ddhh33]

Galaxy 1.9 TDi 2005/55.

 

I had front brake pads changed recently no problem. I then had rear pads changed last week but the brake warning light is still on. Mechanic (none Ford) was told by Ford technical that it "might reset itlsef" so we left it for a week but light is still on as soon as I start the engine.

 

I trust my mechanic to know what he's doing and not to have done anything to have "caused" this light to not go out - any ideas how can I test what is causing the problem before I call him back again ?

 

Thanks

Firstly if this is the Brake warning light then it indicates a fault on your braking system.

ie The car is unsafe to drive !

 

It could just be that the wear connection to the pads ( if fitted ) is not connected or the wrong pads have been used.

 

It could indicate something more serious with the braking system.

 

 

 

Secondly if this is the ABS warning then it is less serious but still requires investigating.

Check the obvious for loose connections.

 

The use of Vagcom ( or similar ) can greatly assist in identifying faults.

Basically it will tell you where the problem is to save you hunting for it.

 

 

 

 

 

I really think you need to have very strong words with your mechanic, he should not have returned the car to you in this condition, the car is potentially unsafe to drive,, and your insurance would be null and void. ( if anyone found out ).

If its the break wear indicator light - coupled with message on dash then the wire is probably broken.

The brake pads have a wire embedded to determine when they are worn. The connections to this can break and cause the light to be on incorrectly. (it did on mine!)

 

Any other indicator and it'sneeds checking immediately as its potentially unsafe as above

I think you need to clarify what light is actually on and what symbols it has and colour. your post is titled regarding ABS sensors yet you talk about brake warning lights and changing brake pads, I ask about the colour as there is more than 1 brake warning light

If it is the wear indicator light that is on then so long as the circuit is ok and the wire not broken then it should go out, as said though I think you need to clarify which light is on before we send you down the garden path

I find it strange that your mechanic has changed pads but not sorted or even advised you what the light is all about, either that or you are not telling us all relevent info

Is your mechanic a real one or a Saturday/Sunday morning tinkerer (jack of all trade type) I don't mean to offend him but I have seen too many brake jobs that so called mechanics have supposidly repaired and been in a more dangerous condition when they have finished. The worst that I have recently done was pads that have gone metal to metal with the disc and making a horendous noise yet the "mechanic" said all was ok and fixed the warning light not to come on, the metal part of the pad was gone and when I got it the piston on the caliper had come out and was now leaking fluid hense no pedal pressure, the vented disc had 1 side completely worn out down to the vented section only

If I can find it I will post a picture of a similar job I did about 12/18 months ago which highlights this exactly

Sorry if I have gone a bit OTT but brake are not something you should dismiss lightly

post which light is actually on and the colour and give us the full scenario of why you have done the brakes
