'93 190e 2.6 brakes

I am going off my memory here so forgive me if I am fuzzy. I went to read on this subject but did not find an answer to my particular question or if it was there, I did not understand it.

I did a brake job on my MB and when I took of the rear caliper I removed a bolt(s) that split the caliper in two - brake fluid came out of two holes. As soon as I saw fluid, I figured that I had did it incorrectly. I have worked on American cars before and never seen fluid flow on a brake job. I finshed the job bled the brakes and everything was fine. It is now time again to do the brake job and I want to remove the rear caliper correctly so that no fluid flows out. I only noticed the bolt(s) that I removed. I did not see anything else. What should I be looking for? A pin?

How do I remove the rear caliper to allow me to get to the pads?

The rear caliper does not need to be removed to access the pads, you only need to remove it if you want to remove the rotor. Hammer out the retaining pin and you will be able to pull the pads out. The bolt that you removed seperates the two halves of the caliper, you do not want to remove that.

Thanks for your response. About where is the pin located? What does it look like? Is there two of them per caliper - one top and one bottom? Does it have a special head? Do I need a special tool to punch it out or just a punch?

I really appreciate your help

Look at the caliper and you should be able to see 2 small indents where the pins reside flush to the caliper surface.

Both pins are hammered in horizontally through the body of the caliper till they are seemingly flush to the surrounding surface.

To remove them, you knock them out from the front (with just a punch) and they should eventually move out to the back.

The 2 pins support a retaining clip which holds the pads.The clip has to be removed before you can swap the pads out.

Fitting is reverse.Pads in, fit retaining clip, then hammer pins in from the back of the caliper.

Good luck.

Good description of how to do it, never-the-less.

Don't forget to use some sort of an anit-squeal paste on the backs of the new pads.

I knew i left something out....

Yep, thin film of anti-squeal paste on the backs of the pads and avoid getting any on the friction surfaces of the pads and rotors.
