190D both rear brakes seized. What's wrong?
Went to work today with the 190D and car felt very sluggish 1/2 miles down the road and with a squeaking noise. Tried to turn round to head home but the car stopped in the middle of the road. It seized so bad just did not want to move and stalled the engine. Both rear rotors were hot to touch.
Walked home to take another car, grabbed some tools and hope to move it off to the curb. Jacked up both rear wheels and BOTH rear wheels would not turn. I squirted some water on the rotors/calipers to chill them down, started the car and it grudgingly moved to the side. What is wrong? Master cylinder? It could not be calipers failing at the same time, could it?

I would guess Master Cylinder if both locked up on you. replace it and flush the system. If they got hot enough to lock up, then it can boil the fluid.
Do the pads or calipers smell burnt? If so, then the pads will need replacing, and maybe the calipers. all depends how warm things got. Did your 190 get as hot as the 300D a few months ago? now those were pretty scortched. especially the R/R. Charlie

I would replace your rubber brake lines as well. If they are old they can deteriorate and make a mess of the fluid and cause sticking calipers.

If you cooled the rotors down with water you may have warped them so you may need new ones of those as well.

how are the pads? Maybe they are both worn down too far and the pistons extended too far and got stuck? My mechanic just told me that could happen last week as he was recommending I get my front brakes replaced.

From what I have read if your Mastercylinder is holding the pressure in the Brake lines when you loosen the Rear Brake Tubing Nut that connects to the Master Cylinder the Brake Fluid will spurt out a little.

The brake pads are new-ish, all changed within the last year. The rotor and the caliper are OK visually. So it is the MC. Will report back when I change it.

The other thing that can cause a pressure build up is Air in the system but it has been assumed that no Air got into the system.

Happened to me but on a 300d ,the inside of the calipers do get rust after long use, you can rebuild the units but $65 will buy you new ones on each corner.

Are you sure it isn't a malfunction of the parking brake?
