Can anyone offer thoughts on the minimum depth of brake pads before swapping ?

Minimum brake pad depth ?
- Thread starter Tripleblack13

I would swap at 2mm of material left but its up to you. The less material left the more you have to keep checking 
The mothership would probably advise at 60% worn.

I try to change them before the backing plate starts making noises against the disk.
1mm, change them PDQ. Check them regularly and anticipate a change based on the wear YOU experience and what you're intending to do mileage wise. I've just replaced my rear pads at 30k miles (second replacement) as I was in there although they still had a couple on mm to go.

That is the sensible way to do it, and is similar to my approach.
I don't like to worry about stuff, and when I check the liners at every oil change, my consideration is: will the pads make it to the next oil change? By 'make it' I mean that it will still be thicker than the specified lower limit 1mm next time it's checked, and as mentioned above, 1mm is pushing it.
If in doubt if the pads will last until the next check, I prefer to change premature rather than keep checking.
But as far as the OP's question, the answer is that BMW specify minimum 1 mm, back/front.

+1 on that, any lower and they can start to break up, and a new disk is not cheap.

Not yet measured the remaining material. Do they have wear indicator ? I recall on hexheads the retaining pin on the rear caliper had rings engraved in it to show wear.

Usual bollox then a back track One minute the pads disintegrate at 60% then it's ok if they're at just above 1mm

WTF are you on............
Personally I change at 2mm, the extra heat transfer with thinner pads isn't worth the risk.

If you are going to be fully loaded like a camel, might be better to just put some new ones at least on the rear it is only 1 set, and only takes half a beer, video below is fun.

Yeah they dead easy.
Took em all out, measured the lining, cleaned them and put them back in.
Might as you say drop a set in the rear

Well worth replacing the rears, Gs's do seem to have a propensity to go through the rears quite quickly, peace of mind and all that.Yeah they dead easy.

You do not need to remove the caliper
I've never seen it mentioned in the BMW manual.
However, as the rear caliper is a singel side piston caliper, there are slider pins.
If there is any unbalance in wear between the two pads, this will be an indication for sticky sliders.
On my own bikes I try to move the caliper sideways when the pads are out. This will reveal if the slider pins are stuck.
So far it has never caused any problem on any of my bikes, so it may be an overkill on my side.
On the other hand, that is my DIY privilege
