250 Brembo pad wear sensor?

  1. Hi Guys

    Me with the squeaky brakes again :smiley: My dad and I have finally managed to get the front passenger wheel off and had a proper good look at everything. The discs do seem fairly worn down but you can still see the grooves in them on both sides and they seem to be ok. The pads though seem to be prettylow, especially on the backside of the caliper, nearest the suspension.

    We also noticed a small clip on the frontside pad, at the bottom of it. This we believe after rotating the disc is what is causing the squeak!! I think this is some sort of wear sensor but does it actually give any other feedback (electronical or dashboard light etc) or does it just squeak once it touches the disc??

    Looks like this (taken from the net)

    As you know, I am getting rid of the 250 in the next month or two as part exchange with a Renault dealer for a shiny 275 ... so to limp along until then, would simply prising the tiny clip away from the disc work? Obviously it wouldn't be recommended but the pads look like they have about 2mm left on them so I'm assuming there might be a bit of leeway on it?

    Cheers for listening again guys and any advise again would be great.

    Many thanks

  2. You discs look fine, look pretty new actually. If you have only got about 2mm left on them then I would change the pads. OEM pads are pretty cheap and a doddle to fit.
     
  3. Just to point out, that photo is not mine, its just a stock image I found to show the sensor clip I am talking about. My discs are much, much lower than them (will try and get some real photos in a mo before I put the wheel back on)

    250 Brembos do not have any type of sensor at all, That image isn't even the same type of caliber that ours uses.

    Get a photo of the actual part off your car, you might find its actually a bit off yours that has snapped off
     
  5. If it is that making the noise the noise then bending it would solve the problem. Even though you are changing the car I'd replace those pads, there is hardly any meat on them and I wouldn't want to have to do an emergency stop if I were u.

    First time i have seen that on pads for ours and that includes several sets of OEM stuff along with the myriad of performance stuff i have used, It isn't a sensor just a wear marker

    as said just a wear marker, so I assume you are pretty low, if it's going in next week is take it in any longer and tbh you would want to change them imo
     
  8. Don't forget there is a legal limit for your pads.

    Eh?

    Its just an mot fail/advisory.
     
  10. Ok. But I'm sure if a driver had an accident six months before an MOT was due and it was deemed his breaks were at fault. Then potentially as the owner of that vehicle you might end up in pretty hot water legally (depending on the severity of the accident) and I wouldn't expect an insurance company to pay out. Just because it has a valid MOT certificate doesn't mean you don't have a legal obligation to keep the vehicle roadworthy. This is just my opinion and I'm not looking at getting in to any petty arguments.
     
  11. Thanks for commenting guys and have taking all your opinions on board. For now, I've slightly levered the wear marker up, not even by a mm to just stop the squeaking for now. Hopefully under some seriously slow and low rev / early, early braking driving this will last until the new car comes in a month or so. If not, I now feel a lot more confident in changing the pads myself, so will do that and not have to rely on specialist etc.

    I've posted some pics of the discs and pads below as well just to show the state of them.

    discs are well worn but look serviceable for now, tbh the pads look like they have life in them too from pic 2. changing is a piece of piss if you do need to change though.

    Yeah plenty left in them, I would worry about changing them.

    Ive done a trackday with pads of similar thickness....
