Why did VW decide to use Allen bolts inside little rubber boots on bloody brake calipers?
Reminds me of doing the pads on my VFR.
Spent an hour hammering the f*ck out of the pad retaining pins without shifting them.
Then I had a closer look and found they had an allen head on them.
Useful where you want a smaller head on a bolt. Or in a bar - like the slides on many calipers.
If they're the slides you're referring to it's not VW but the brake maker.
ATE iirc. And I'll bet the heads on those slider pins are 7mm not 6 or 8mm hex too. Bastards.

A set of 3/8 drive ones for your socket set from the likes of Halfords includes the two needed for those brakes.
Indeed. That's where I bought the ones I needed for the calipers on the old E34.

I'm beginning to suspect that they're 6.5 - 6mm is slightly too large, 7 is too big.

They really are a 7mm. Don't trust allen keys. Get a 3/8" set of hex tips as DaveP suggested. Tap the tip into the hex slider pin with a small hammer first to seat it properly. Oh and by the way, I'll bet they are stainless steel pins too. When you do get the tip in, take *great* care when undoing them. _Any_ off axis torque and they'll snap off the small threaded section in the caliper mounting plate. Then the fun begins...

I've got the proper allen key for the job, you should find one in your local motor factors for a few quid. It's 7mm IIRC, and quite large.
i attempted to change pads on my MK1 MR2, guess what i did :-) my mate wasn't to happy when i drove to him with 3 calipers and one slightly lose one with a bolt stuck in it.
i don't do pads myself anymore can't be trusted :-P
