Klaus,

Thanks a lot for the info.

As to the rotors, thickness seems to be ok; but rear left one seemed to be worn more than the right one. the wearing of the right rotor is not even, especially on the inner side. On the shoe portion, there seems no wearing on the right rotor. left side seems normal. (by the way, friction portion of the left shoes fell off.) If I have to get a new caliper, I tend to get new rotors too. I am going to call Tasca to find out the differences among the calipers I listed in my previous post.

It was getting dark when I finished up the parking brake job so I didn't get a careful look at the piston. I didn't grease it either; but I sprayed some WD-40. I am going to check it again this weekend. I will grease the sliding pins too.

brake fluid has been flushed with superblue regularly .
