It reads like a typical case of warped brake rotors/discs.

Warping occurs when you sit on the brakes for long periods. It traditionally happens when you drive down a steep hill with the brakes applied constantly - this causes the pads to overheat and damage the discs or cause uneven wear.

If the warping is causing the steering wheel to vibrate then I would argue this is a very serious safety issue. However, I'm disappointed to read that the dealer didn't inspect the brakes before replacing the bushes.

I would suggest taking your car to an independent Land Rover specialist as the cost of the repair will be cheaper: good-garage-guide.honestjohn.co.uk/directory/searc...r
