Mini Roadster Brake Fluid Issue

Low brake fluid usually triggers the warning light. Are you getting any messages on the dash? Strange brake pedal feel could point to air in the brake system, or potentially a leak. Have you checked the brake lines for any obvious signs of fluid?

The warning light does come on intermittently. Where exactly should I check for leaks in the brake system?

If the warning light is intermittent with low brake fluid, topping it off isn't the solution, as the fluid level is dropping for a reason. Check around each wheel for any wet spots, that's where the brake lines connect to the calipers. Given the symptoms, it's best to have a workshop take a look at your car brakes.

Just wanted to say thanks for the advice. Turns out it was worn front car brakes, like you suggested. Cost me 480€ to get sorted.
