I think that ship has sailed, he'll not back down now and buy them. You should replace that little screw as soon as possible, it's an MOT failure. Exactly the same effect can be achieved by vigorously pumping the brake pedal. If you want to create a floating disc setup I can supply you with some rubber washers, swap these for the ones on the calipers, job's a gud 'un.
These "wobbly bolt" things, they're effectively wheel bolts with the head slightly squiffy correct? So couldn't the same effect be achieved by thightening a standard bolt & belting the head in the required direction with a big hammer?
You may be on to a winner there Dan Obviously I'd need to replace the disc retaining screw first otherwise it would be pointless bolting the wheel to the disc if the disc itself isn't screwed on properly
If you're still intent on running the floating disc idea, i'd be a bit cautious with that design. That retaining screw is fine for holding on the disc itself, but relying on it to secure the wheel as well may lead to problems further down the line. HTH.
I gave this some (drunken) thought last night. I believe the bending process could be helped somewhat by heating the bolts. I would recommend a plumbers blowtorch (propane/butane mix is best). If a responsible adult isn't available however just whack them in the oven for an hour. If you're in a hurry, the microwave will get them up to temperature lickety-split.
I think that the blow torch may be the best bet, getting hot wheel nuts from the kitchen to the car could be quite hazardous, besides which Mrs Gaz has banned me from using the microwave for car related items ever since my ill advised attempt to test my thermostat in the microwave
You didn't forget to put it in a cup of water did you? Schoolboy error! On a side note microwaves can be used to dry car mats and headlining; stick in a grated lemon at the same time for built-in airfreshener goodness.
