One main problem comes from the rear disk brakes. The surface on the brake-
saddle where the brake-pads should glide in and out have deep worn-out spots (first
mentioned after 100.000 km), where the pads stick - and release immediately when you
press the brake-pedal stronger down with a hard noise. If the fixing-brakes stick you will hear
a metallic scratching noise while driving in either direction.
Workaround: If the worn-out spots are too deep you won't come away without new
brake-saddles anyway. The major cause indeed is a maintenance problem. It is caused by
old brake-pads which stayed too long in the system, tilt and indicate stronger pressure on the
material. It might be also a greasing problem, if the mechanic in the workshop forgets to
grease these surfaces with copper-grease and/or didn't clean the saddle completely.
My experience: You can do this by yourself - like I do. I got used to check the
braking system at least every two month, jack up the car, remove the wheels and look after
the pads. While having anything open, I grease these points with the temperature-stable
copper-grease. That will help. When replacing the brake-pads it is essential to clean the
saddle with a brush on the insides too. But watch out not to damage the silicone cylinder
Don't use a screwdriver for this !
There are special Copper or brass-brushes
available. For greasing the sliding-surfaces use only copper-grease. No oil, no bearing-
grease. Everytime I replaced the rear brake-pads I removed the brake-disks and looked after
the fixing brake, removed all dust and used a copper-spray to grease the mechanical parts.
Of course not the linings and the brake-drum inside the brake-disk. Look for the cables
also, they need to be grease frequently, too.
Reports: None at this time.
