After washing the car (if the car stands for a while) you will see rust coloured powder coating the discs (front & rear). When parking the car after washing, the process of applying the handbrake definitely cleans the rear discs (which will not happen if you only use the regular brakes). So now I am confused.

Here's how I picture you ok, after you wash your car, the disc gets rusty so you get in your car and drive and apply your handbrake. Then you stop your car (by applying your footbrake I assume) and you get out, all four disc is now clean right? That's the reason, you used your footbrake and naturally all four disc will by applied and therefore all four disc are clean. If you still don't get what I say next time after washing your car and with rusty disc, put the car in drive for a slow (and I mean slow) roll and use your handbrake to stop your car (if possible) when the car comes to a complete stop then put your car back in P (assuming you have auto) step out to see if your disc is still clean.

[/quote]OK I did the test - see pics below.
After braking with the handbrake only there was only minimal cleaning of the discs.
I assume this was only due to slight rubbing of the pads on the discs.
Glad to have learnt something new
But I still need to know if performing this handbrake procedure once per week is enough?

Have you seen a rotor (not on the car) the part for the hand brake is behind those holes.? The parking brake does not use the disc part, so you rear disc may look clean but the parking brake could be a different story.

Just that I didnt know there is one in the E60 and didnt know it was behind the part inside, behind the holes where the bolts would come out... Intersting... now I can picture how the parking brake works...
Ok I guess its good to clean it out then once in a while... BUT wouldnt that wear it out and cause us to have to goto the dealer to re-adjust the parking brake often?
Now I'm curious how the MINI parking brakes work hehehe BMW made...

well, I can't say I remember to intentionally apply it when coming to a stop, however I often apply it then forget to take it off when starting to drive, so I guess it gets a little bit of use that way.

All parking brakes works the same way if they have a four disc setup. But parking brakes need adjustment once in a while but I always put my parking brake on after I park so that I don't put stress on the P gear in the auto tranny. After all is cheaper to replace the parking brake than the tranny.

Just curious... why cant they just use the same system? Use the Disc brake and have that tied to the cable of the paking brake?
I too ALWAYS use the parking brake... i dont like resting my car against the transmission.

[/quote]The caliper slides on two rods, when you apply the brake, the piston pushes the inner pad out against your disc. When the inner pad hits the rotor the caliper will pull the outer pad in so the two brake pad squeeze the rotor which stop your car. Then piston is work by hydraulic, sounds simple but very complicated and the system does not work with a wire. The drum brake can work with a wire pulling it that's why they use that for the parking brake, plus if they put emergency brake in the primary disc brake, if one system fail than the whole system fail including the emergency brake (safty measures).
