Brakes
Brake pad wear sensor light came on the other day. Guess it's that time. Got a few questions though-
1. I think it is the fronts and my reasoning is that they are maybe a year older than the rear and the fronts usually wear quicker anyway. Is that safe to assume? The front ones have about 40-50k on them.
2. The dash light is my only warning- I have no vibrations, squeaking or other noises associated with worn brakes. Given that, could I do just the pads/wear sensor and leave the rotors alone?17 Discovery 5 HSE Si6, Fuji White on brown | 07 LR3 SE 4.4 Java Black on Alpaca

It really is impossible to say without seeing them but my best guess at 50,000 would be they need changing. I personally always change discs/rotors at the same time as the pads.You guys are gonna be busier than a test bench in a plunger factory!

best to pull the wheel off and have a look as there's only one sensor on each axle.one front and one rear.fronts are good and look for Bodsies brake bible how to.

I also tend to replace the rotors with the pads especially at 50,000 or is that 50,000KM?
Bodsie brake bible is the thing you need. The torx screw holding the rotor on can be difficult to remove. I used an impact driver to tighten the loosen then used a 32mm socket to hold the rotor still so I could then undo the torx

Look through the "spokes" on the wheel and you can see and estimate the wear on the disk(rotor), feel for a step on the outer radius of the face of the disk(only when cold), there will be a similar step on the inner radius, the height of the step will tell you how much the disk is worn and look for any gauging on the disk face, this is a good tip when buying a car to access disk wear and there is no need to remove the wheels.It can when others can't,
It will when others won't,
It goes where others don't.

I would also add - don't assume that both pads on each wheel wear evenly. In my experience, one wears faster (I think it is the one that does not touch the piston). So, if you eyeball one pad, you could be looking at the one with less wear.2005, TDV6 S, Auto, 190k miles, owned from new, V8 Brake Upgrade, Nancom Evo, RLD protector, BAS EGR blanking & Remap, separate ATF cooler, changing all the fluids ahead of time.

Thanks much for the tips everyone. I will check the rotors for the "step" later tonight when it cools. I am pretty much set though on replacing them anyway, but this might give an indication of if it's front or rear.17 Discovery 5 HSE Si6, Fuji White on brown | 07 LR3 SE 4.4 Java Black on Alpaca

Have you checked the brake pad wear sensor wire? I just replaced mine today and when connecting it to the truck I had to attempt two times because the connector end wasn't locking properly (took a couple tries). If it's not connected or the wire it broken you'll get your light your speak of.1998 Discovery LSE - Gold, 249,000+ miles, completely stock

Did you fit a new sensor cable? What about the rears?- check the rear off side pads for wear.It can when others can't,
It will when others won't,
It goes where others don't.

The rears are good I think, I will check the sensor again.17 Discovery 5 HSE Si6, Fuji White on brown | 07 LR3 SE 4.4 Java Black on Alpaca

Just checked it and it seemed ok- I guess a better question to ask is, does the warning usually clear itself for others?17 Discovery 5 HSE Si6, Fuji White on brown | 07 LR3 SE 4.4 Java Black on Alpaca
