Today I picked up set of front and rear brake pads for the E300. First thing that I realized is that the 95 E300's have the floating calipers, they are different from the 95 E320's, 420's right? Once I loosened the 2 bolts holding the caliper to the bracket I took out the brake pads. I realized that the pads still have about 8mm of the lining left. After a closer inspection I found out that the brake wear sensor was actually rubbing against the outer rim of the rotor. The rim is actually pretty tall and that indicates that the rotors should be changed. I know I should consult the min rotor thickness but the rotor seems worn. BTW the PO said that the rotors are original.

Anyways to make my boring story short I will get some new OEM rotors and put them on with the new brake pads. As for the rear brakes, the pads still have a lot of meat left and the rotors are in good shape.

Now my questions:

1. The dealer did not provide any brake paste, anti-squeal paste, do I need it?

2. I bought brake cleaner, is it a good idea to spray the caliper and the surroundings to clean the brake dust?

3. To take off the rotors I just undo the 2 big bolts that hold the caliper bracket and the allen nut that hold the rotor to the hub ?

4. Do I break-in the new rotors/pads

5. The inside of the caliper piston has some surface rust, is there anything that I can do?
6. Phew! I think thats it for now

BTW: the MB brake pad that I bought are made by Pagid, the current pads have the MB emblem on it and are made by Textar

I think I will wash the rims inside out when the wheels are off.
