update: asked on a U.K. forum, reply: I used one of their kits on my offside front caliper about 18 months ago for my E32. it has been fine since. I replaced the nearside prior to that by buying an exchange caliper through our local motor factors. The rebuild kit was was about a third the price of the exchange kit. Only difficulty i experienced was fitting the new dust seal in, that was awkward. I would be happy to use them again.
