Rear wheels getting covered in more brake dust than the fronts?

[James28]

As in the title, for some reason my rear wheels seem to be getting dirtier than the fronts in the same space of time.
Pretty sure its brake dust..

Could this be highlighting a problem with my rear brakes? Seems a bit weird, as I thought they hardly did anything..

Mine do this. Also had 4 set of pads in 20k miles. Think I may have a problem...

4 sets of pads on the rear in 20k??? Think they may be a problem indeed!haha

James28, I thought I had the same the other day, turned out to be road cr#p on them, making it look like it.

I wash the wheels quite regularly. They definitely do seem to get dirtier than the fronts for some reason.
Pretty sure its brake dust too. And its more obvious now I've got turini's as more space/spokes for dirt/dust to collect.

Is there anyway to check the rear brakes or anything? I only changed them about half a year ago.

My rear brakes are pretty much brand new and the proper renault parts. They do seem to chuck off quite alot of dust.
I dont know if its because the wheels dont steer that it builds up more.

Jack rear of the car up with handbrake off and spin the wheels there should be no resistance if there is your brakes are likely binding.

Looks like it could be normal then.
Guess I could jack it up and have a look.
Just seems a bit weird rears get dirtier/dustier than the fronts, when in theory the front brakes should be doing far more work.

Could be a caliper sticking causing more wear than necessary, do as dannycivic says and jack the rear up and spin the wheels ( without the handbrake on obviously)!

 

[James28]

I'll try that then cheers.
Wouldn't be anything to do with that bias thing on the rear axle?
Although apparently it only adjusts the height of the xenons, not braking bias?

check for play in the wheelbearings, and if the rear brakes are dragging

 

[James28]

Okay cheers. Will do.

Should hopefully be alright, as I said not long changed the discs and pads, and I torqued the hub nut up correctly.
