Has the car been serviced at all?
The grinding could be worn brake pads, wheel bearing or CV joint.
To check bearing jack up suspect wheel, support car on stand for safety, grip wheel top and bottom and try to rock it in and out, if there's any movement the bearing may be worn.
If OK remove the wheel and visually check the brake pads and disc.
Describe the dash light which is coming on, no offence but I spent ages trying to sort an EML problem over the internet. Turned out it wasn't the EML at all, it was the low screenwash warning light!!
What year and engine is the car, on some you can read the fault codes without special equipment.
