Started to do my front brakes today.

I found I need to replace the left front caliper, which I had not anticipated.

When I look at the parts catalogues, I see only ATE or NuGeon (rebuilt ATE) available, though there is a reference to "Mercedes original" (with no pic).

I'm attaching a pic of what is on my car. I guess these are Bendix, right?

I would rather get one Bendix than two ATE, if possible. The other caliper is fine and I have other things to spend $$$ on, on this car.

Anyone know why only Monkey Sauce appears to list rebuilt Bendix?

The only answer I have is to rebuild your BENDIX.
I suggest you rebuild both of them at the same time.

Here are the kits.

You are in Canada. So what works here in the US might not help. Here the local Auto Part Chain Stores seem to have Bendix and ATE.

If you pull out the Pistons and the Bore inside is OK you could rebuild it yourself.

I'm not against rebuilding a spare set, but having never attempted something like that before, I wouldn't trust myself to not mess something up... and right now I don't have a second car so I can't chance the 300d being inop for any length of time.

From memory, I think my Coupe also may have Bendix. It's a potted plant at the moment so I could pull them I guess.

Question: the problem with my left front is that one piston is seized. How to I extract it?

yeah, the coupe will have direct bolt on calipers.
the way to pop a seized piston is with an adapter threaded into the bleed screw/fluid line, connected to a grease gun, with a SERIOUS c-clamp setup holding the other side in.

I like new calipers, because brakes are one of those things that you really don't want to mess up. Right now, it would appear the only ones that are easy to get are the Genuine Mercedes ones. Other parts houses may not have the correct part number listed (we're checking on that).

To revive an musty thread-

I have one seized caliper in the front and would like to replace just one. What is the importance of matching brands between left and right calipers as indicated in the catalog?
And why the request for a particular pad?

part number is 123-420-01-83-M234
listed on this page 1983 Mercedes-Benz 300TD Wagon - Brake Hydraulics - Page 1

Thanks

Unequal caliper characteristics can result in uneven braking, pulling to a side, and uneven wear. At time of doing brakes is when most folks try truing up both sides, like always doing all pads across the axle etc.. Otherwise you're going in twice as often doing maintain on half the car and having to keep all that straight in your records. That's all.

The piston bore diameter of ATE is different from BENDIX, the minimum variation of bore is at least 4 millimeters per piston.
You must have matching application pressure between the two front axle or two rear axle calipers, or a left/right pull happens..

Is this to say that if I put on a new or rebuilt ate on one side as long as it matches with an ate on the other side then braking will be eve? Even if the ate manufacturer may be different.?

Now there is a concept. An ate caliper not manufacutred by ate!!!

Am I missing something? I thought that ate and bendix, were two different styles of calipers with different companies making them, ie Cardone, Centric, neugen, Beck arnley. Are those companies just re builders of parts originally manufactured by ate or bendix?

when is the last time you changed your brake fluid? it must be changed every 2 years, regardless of miles driven. the only time i've seen seized calipers is on severely neglected cars that haven't changed their brake fluid in many years. brake fluid absorbs water from the air, and rots the entire system from the inside out, deteriorating all the seals, and corroding the insides of the calipers until the pistons seize in the bore.

Bendix and ATE/Tevis are different original equipment manufacturers.
