How many pad wear sensors?

[Philip1972]

Popping news brakes on this weekend, but just wondered how many wear sensors there are?

1 per side or just 1?

Thanks

My 2006 X164 has one sensor front and rear.

One per axle.

Reuse them if they not broken.

I have none on the rear of my CLK I bought two in preparation to do the brakes, so now have one spare for the next time I need pads

Yeh my CLK only has front, my E has front and rear though.

One on the rear of mine (LH side) , 2 new ones came in the box with the new pads.

ML270 has one at each corner, easy to refit to new pads
