Rear Brake Pads Dustier than Front

[clubhead]

It has always been the case of the front pads having more dust (dirtier wheels) than the rears. Only makes sense as the front brakes does most of the work. After I changed pads (from Performance Friction to Porterfield R4S), it seemed to be the other way round. My front wheels would be clean after a week but the rear wheels would be coated with dust :(

My car has only about 35k miles on it but is 7 years old. Does anyone reckon the rear caliper seals need servicing already? How do I check whether the pistons are stuck or working well?

This is my layman's way of checking... if the brake pads are dragging in the back, you should see a drop in your gas mileage as well as the pistons would be pretty hot... even after just moderate driving (without hard braking).

Also, you could roll your window down... and as your moving forward, put it in neutral / turn off engine and listen for some sort of dragging sound coming from the rear wheel.

Finally, it is possible that the new pads you bought are just a lot softer and put out a lot more dust than what you are used to.

Forgot to mention that I changed both my front/rear pads out to the new Porterfield at the same time...
