I've had to break and replace two beru rotor arms on my 260E because of the 3 weird allen key constructed bolts that hold the rotor arm.
The bolts have round smooth heads and the allen key fits into a hexagonal sleeve or collar placed in a circular hole drilled into their centres, rather than as in a normal allen key bolt where a hexagon hole is drilled directly into the metal.
The trouble is the sleeves flatten out so they bolts can't be removed with the same allen key used to tighten them.
Can anyone shed any light on this / recommend a decent brand that has sane bolts?
