My car has a bit of a problem with more than normal brake dust on the rear wheels. Took it to my local Independent and as it needed discs and pads I said to check out and even if one caliper was binding at all replace them both - a proverbial blank cheque. I also said they should check out the function of the EPB while they were at it.

They did find a problem with the EPB pads but nothing else and said the calipers were retracting as they should - I still get what I think is excessive brake dust.

I also tried to use the routine on my IDTool that relates to the EPB (unjamming procedure) but although the brake appears to work fine it reported a fault and suggested there was no module there?

I'd appreciate some feedback if any of you have had similar issues  Geoff

Perhaps LTFA...

What brake pads were used? Some pads are a softer compound, wearing away faster, resulting in more brake dust. Could be something as simple as that
