Hi, just bought a s type 2004 2.5 petrol 35000 miles but been stood for 3 years. On driving home I found in cruise it was slowing down and applying the brakes. Also when not in cruise control, if you touched the brakes lightly they would continue braking. To stop this I had to put my foot under the brake pedal, but if you dabed the brakes they would release normally. Help needed please.
