The nuts are special ones (ie not the common acorn nuts) with a shank to go down into the hole. They engage with over 10 threads, more than the original and legally-required 9 threads, so all is well in that dept. I'm undecided yet as to which rims will be fitted for certification but can't think of any reason why not to have the X5 rims.
Hi Graeme,
do you want to sell the brake callipers you have removed?
No, in case I want to refit them sometime.
the standard for the test is a dry flat road (I assume its ment to be bitumen)
After bedding in the pads on the first sealed road, the brakes are more sensitive and require less pressure than the 45K worn originals. During the bedding-in, I had to remind myself to stop at maximum retardation rather than just very quickly because they were so effective. I thought the vehicle was about to do a forward roll - it was down-hill afterall! I didn't expect the new tyres would grip that well.
