Success!!
Just completed the job and returned from a test drive. The job is definitely a DIY'er. For my vintage of the 300E you have to open up the caliper to get access to the pads. There are two bolts that hold the caliper on and you need a 13mm socket to unscrew the bolt and a 15mm wrench to act a counter hold on the "inner" part of the bolt. Once you have the car jacked up and securely on jack stands. Remove the tire and you will see the top and bottom bolts which hold the "floating" caliper closed. Remove the bottom bolt and then just loosen the top bolt. You can then swing the caliper up and remove the pads. Next remove the cap on the brake fluid reservoir and place a rag over the opening to absorb any lost fluid from when you "squeeze" the caliper piston back. I used a large "C" clamp with a flat piece of wood to cover the end of the piston. Tighten the clamp till the piston is back in position. Apply anti-squeal paste to the backs and sides of the new pads. You should also install brake sensors to two of the pads. My '88 300E has one sensor on each of the front wheels. Some other models may use four sensors. Place the new pads in the pad guides in the same order as the old pads. Then lower the caliper housing down, being sure to "fish" the sensor wire through the small opening in the caliper. Re-tighten the bolts and plug in the sensor wire, then close the sensor cover. Repeat the procedure for the other side. Replace the wheels and lower the car. Pump the brakes up until the pedal gets firm and check the fluid level. Take a test drive.
