Mini cooper Warning lights for abs, low tire,traction comes on

Ok, check the brake fluid level for a start. This could mean a few things. Your brake pads might be worn down, which would bring a yellow warning light on(triangle), at the same time with the pads being low it will have displaced the fluid, making the level low, this would be a red light on. Now because of this the body control module has detected these faults, will have turned the abs off, hence the abs light.
If brake fluid is low, this could confirm my theory.
If its low, top up with dot 5 brake fluid and take to garage to have new pads fitted.
