Today I removed all four wheels and gave them a good clean and a wax. Two coats on the inner surfaces. Also gave the calipers back their lovely red shine. Wheel bolts seemed a bit too easy to undo but I used my torque wrench to tighten them properly.
Wasn't overly impressed to find one of the disc retaining screws fall out as I removed the wheel.
Also, as it wasn't specified in the handbook, does anyone know what the recommended number of times to scrape your knuckles on the ground is when using the supplied jack?
