As Paul has said.
But as it has been standing I would add to the above list:
Remove all brake pads, clean the callipers, check the pistons are free, lube and refit. Adjust the handbrake. Whilst the wheels are off, visually check all the flexible hoses and shocks for leakage. Check the suspension bushes for play - use a small pry bar to exert some pressure on them. Check all the rubber boots on the steering knuckles. Take the 'long route' to the MOT and give the brakes a regular dip on the pedal to polish the discs.
Good luck with the test.
