[rallure]

ok well today i gave the car a much needed wash and the first time i started her up the master warning light and brake system warning light stayed on after ive released the handbrake. ive checked the brake fluid level and thats fine so whats happened?

i sometimes have this problem, make sure the doors boot an bonet are shut an that all the sensors for the interior light etc r all working correctly, an also is the wire to the brake fluid is all connected, giving the reseviour a tap sometimes helps!
