Brake Pad installation is easy for Mercedes Benz 1984 to 1995 E-Class W-124 series. Do not remove calipers from spindle! I installed cheap semi-metallic pads ($28) similar to Mercedes-Benz factory originals. Modern ceramic pads may be better especially for less brake dust. Be sure to buy new wear sensors too as they are cheap and easy to break. The sensor is easy to replace. Rear brake pads should be similar.
