On Friday I completed a 3-4 mile journey. On 4 occasions during that journey when I pressed my brake pedal it felt like something had given way under my foot. There was a clanking noise and my car just rolled on (felt like I was speeding up like braking on ice). It stopped eventually, as if something kicked in after the 'clanking noise'.
I checked the dash for warning lights, but nothing lit up.
The next morning I took it into the garage (with my husband driving in front so he could brake gently in front of me), and (sods law) the brakes felt fine; however, the ABS sensor light stayed on throughout the journey (which it hadn't done the prevous journey).
The verdict from the garage is simply that the ABS sensor needs replacing.
To me, this seems like a rather lazy diagnosis! Whilst it may explain the ABS warning light, it doesn't really explain my brakes not working properly on Friday.
Can a faulty sensor affect the actual braking?
Thanks for reading!

It probably is exactly what he said. Check the basics of your brakes. Brake fluid? Brakes pads, rotors, brakes might need to be bled (air in the brake lines) Sometimes the ...master cylinder thingy (not sure what its called)can cause the sensor to come on. If your worried that the mechanic didn't do a good job..Take it to a brake specialist. A friend of mine has a similar problem on her car. On occasion the brakes will go straight the floor. Then all of a sudden they go back to normal. Shes never really gotten it fixed...simply because no one can figure it out. sometimes my brakes act goofy if they get wet. cover the basics...then see what happens. Could have been a fluke thing. But on the other hand sometimes mechanics have a habit of blowing off women.
Just call the mechanic who did the work and ask him what he did to check the brakes. He may have done all of the things I listed and couldn't find anything.

Yes it can. The sensor may be the problem, or it may only be part of the problem. It sounds to me like your master cylinder is failing too.
Your car is not a fool proof piece of machinery with redundancies to catch every possible failure. A failed light bulb or cigar lighter can cause many unforeseen and potentially deadly situations. An ABS sensor is no different. And the diagnostics tools available aren't absolute either. Many error codes point to sensors, but sensors may not be the absolute problem. The OBD II systems used to run your car has codes that can be misleading.
I think your mechanic is right on the money. I would still have the condition of the master cylinder checked or even replaced.
If you don't like what a mechanic tells you, get a second opinion. But if your husband was with you while the car was being looked at, I doubt a mechanic would take a chance on snowing both of you.

There is a problem with your brakes. the sensor has nothing to do with whether they work or not.

It sounds to me like one of your brake pads is loose,maybe yourcaliper is worn,allowing pad to shift.Get a second opion.
