Is it normal for pads to wear uneven?

Not to sure its a problem but would just like to check. Car drives perfectly fine brakes nice and smoothly etc.

On my way home from work on friday I had the low pad wear indicator pop up. I only replaced the rears last year so I new it the fronts that needs doing. When I get home I have a quick visual check and the fronts and they look fine. So today I poped the wheel off to check the other side of the disc and it is indeed reached its limit.

Im sure when i replace my rear pads and disc the wear was pretty much even.

I brought my car with 24K on it and now it just over 70K Theres a small lip on the disc so I might as well replace them as well.


I replace my rears with some Pagid pads and disc from ECP, seeing as the fronts do most the work I was thinking of using Something like Brembo Max disc found here:

Most probably use there pads or EBC.

any views, :D
 
50K out of a set of discs and pads isnt bad. I would clean the sliders and re-grease them too (with correct grease), they may of been sticking a bit on one side.
 
I was doing a lot of motor way miles before but i dont any more. Plan on buying all the bits and fitting next weekend. :D
 
It's not unusual for the inboard pads to have a bit more wear, they get the direct force of the piston, whereas the outboard pads indirectly get the reaction force. That's why the wear sensor is on that side. The unevenness you have experienced is a bit much though, as foxy-stoat said, the sliders appear to be sticking or binding.
 
Depends on driving style really. On balance you'd expect a reasonably even amount of wear, but if you're turning and braking going right 60% of the time, the lefts would get more loan and use more brake disc overtime. My brakes were slightly imbalanced back in November, which ended up in the tailend kicking out whilst it was wet/raining as I was going round a very subtle bend - I touched the brakes, which was enough to unsettle the rear of the car.

Best sort it sooner rather than later.
 
Ill have a look at the weekend, hopefully a cleanup and re-gease the sliders as mentioned will resolve any problems if they exist. Would the copper slip grease be ok?
