Brake pad thickness when new
Discussion
Simple question you might think?
I couldn't find any sensible answers trawling the Forums on the Web to compare my pad wear with the new without buying them first.
Of course, different makes are similar but use different thicknesses of fibre.
I changed all my pads on the Range Rover Sport and was shocked by how much was left on the front pads given that no warning lights had come on the dash.
Looking at the brake information online almost all of the makers show a dimension diagram and give a thickness of the pad but this does include the total including the metal backing plate.
I hadn't taken a pic of my new ones as the garage has a dirt floor (I know, but not just dirty, but earth), and not wanting to use the camera there with greasy hands and what with the floor I had left the camera at home.
You can work it out by minusing the metal backing from published pad thickness.
Mine were 11.6mm. fibre thickness from new.
Casting around for a comparison, this water pipe off the PC is the same width as the new pad fibre so hardly any mileage left in them.
I will be checking the wear a lot sooner now. Regards.

Any sensor wires fitted to the other pads?
Low pad warning lights usually rely on wearing down the pads into the wire of the sensor wire which is embedded in the friction material which then completes the circuit by rubbing against the disc & the warning light comes on.
If they aren't fitted or aren't connected then you won't get a warning light.

Hi Paintman, Thanks for the reply.
On the RR Sport there are just two brake warning low pad wires clipped on and connected to the front left and rear right outer pads.
They were both in good condition as were the pad carriers and keepers considering the wear shown.
I imported the car from Texas and live in SW France so it hasn't had a hard wet life like me.
On YouTube vids they had the backing shields on the fronts eaten right through with rust with the stainless pad keepers in the same state,
whereas mine look as good as new and that's on a 2008 car.
My biggest struggle was routing the pad wires round the back of the air suspension pots by feel as you cant get to them otherwise.
Oh, and getting the 20" wheels lined up and back on the studs.
At one point I thought the car would have to be sold as a three wheeler.
Regards.
