Thank you for that mate I really appreciate it I am in two minds to replace the front discs and pads because I have done 20k since I have owned her and can't see on the seat print out if they have ever been changed and don't to be wasting money on pads that will need doing again but money is always a factor nowadays isn't it mate
I think that the first thing that you need to do is to get a front wheel off and work out which version of front brakes are fitted to your car, especially as you bought it second hand. Some versions of front brakes will have brake pads will have an embedded wear sensor on a single pad on the first - either right or left side inner pad, and some versions of front brakes will have a separate wear sensor that clips onto a single pad - either right or left side inner pad, when you examine the pads you will be able to work out if the wear sensor is embedded into the pad, or is a stand alone part that is clipped onto the outer edge of a single pad. As said already, is the pad wear light is "On" then that stand alone wear sensor needs replacing along with the set of pads. Also measure the overall diameter of these front discs. Also as said already, if the discs look okay and are still within the allowed wear range, then only the pads need replacing.
Although, there is an outside chance that this is a wiring
problem - if you find the pad wear to be okay - but that is just highlighting what might actually be wrong with your car, first of all you really do need to examine the brakes, just grabbing maybe suitable or not versions of brake pads is not the way to go. Plus clean up the calliper and carriers before fitting or re-fitting the pads.
