w123 rear caliper/rotor upgrade?
 

i was just at the yard today and saw a late 123 wagon with ate caliper. caliper didn't look much larger than the sedan wagon, so i decided to grab the bendix rear caliper and rotor off a sedan and put it side by side with the wagon rear caliper--pretty much identical. pulled off the rotors, they were exactly the same diameter, hat height, thickness, everything.

so the question is, are there any rear bolt-on rotor/caliper for the w123 sedan? i'm about to do the w126 front brake install, but i don't want brake bias for the rear.

also for those who have done the w126 fronts onto the w123, how does the stock 123 brake booster hold up--does it need to be upgraded to a bigger one or can it handle the bigger brakes?

Are you getting W126 front brakes from a 1st gen or 2nd gen model? If it's a 2nd gen model, you'll need to upgrade to 15+ in rims if you don't have them already.

currently rockin' 16x7 et37 clk lightweights. weigh in at 13lbs each

I was under the impression that the rear wagon pistons were slightly larger than the sedans. Whether its enough to cause brake bias, I don't know. Probably not if you replaced both rears.

Looks like somebody is back from time-out! ;)

anyone know if the brake booster on a 300dt will be big enough to handle w126 brakes up front, or whether upping it to the w126 booster is recommended?

I upgraded to 1st gen. 126 brakes on my TD. The rear rotors and calipers are exactly the same on a 123 and a 1st gen. 126. The booster works fine as well.

If you're going to 2nd gen. 126, I believe you'll need the booster too. I'm not sure if the rear brakes on the 2nd gen. 126 are different than the 123.

are the td boosters bigger than ones on a sedan?
