how do i change the brake pads on my 93 benz E-class?

Answer 1

Front and rear are different.

Start with the rears, they are very simple. On each caliper, there are two pins that hold a retaining spring in place. Use a 5mm punch to drive them out of the caliper. Be careful not to lose the spring. Once the pins and the spring are out, the pads can be lifted out with a screw driver. Use a screwdriver to carefully push the pistons back into the calipers, taking care not to damage the seals. Now just drop in the new pads. If there are wear sensors, install a new set. Then replace the spring and pins, and you're done. If you want to replace the rotors, then remove the two bolts that hold the caliper in place. Use some wire to support the caliper while you work, so that you don't have to remove the hose. There is an allen screw that holds the rotor in place. Remove it: these often rust and need to be drilled out, but you can reassemble them without the allen screw if necessary. Now pull the rotor. It will probably offer a lot of resistance. Whack the side of the hub with a hammer, and it will pop off. Replacement is the opposite of removal.

The fronts are floating calipers. You need to unbolt the calipers and remove & replace the pads from the bottom. Otherwise, it's the same as the rears.
