What are the caliper brackets made of on the W124? Are they cast iron, or cast steel? Are they weldable or tricky like cast iron? If I were to weld onto them, would I need to throw them in an oven and let them cool down slowly over time?

Working on caliper adapters for Redemption and wondering if welding was an option or if I should just stick with my gut idea and make it a bolt-on process.

I identify forged vs cast by the parting line on the casting, if there is one. Cast has a small, tight parting line, forged is wide and ground flush. I think there's an oxy acetylene torch trick too. Something like cast makes a spark shower with a torch.

Forged requires pre heat and slow cool down.

Anything that I've needed to identify on a Merc front end ended up being forged.

When in doubt, preheat and cool slowly-any weld will be improved by heating even basic brackets.

larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

Intuition tells me to avoid welding calipers.

A friend did a caliper conversion and he fabricated caliper-hub adapter brackets from 10mm mild steel plate, IIRC he fitted OEM fitment Brembo calipers from an Evo to something European..




Installed:

OM606/722.6, big IC, W220 brakes.
Planned:
DIY manifold, compound, 722.6 controller, built IP.
[i]Less rust..

I decided that I'm not going to weld anything to the calipers and brackets a while ago, I never did update this thread. At the moment I'm trying to figure out the best way to get the MB rotors and hubs onto my setup. Still planning a lot, and I won't act until I have a clear plan. Smile

The Swedish guy who made this thread has some pics of caliper adapters he made for ML calipers onto his 190 for some inspiration.

with a time and a budget crunch I'm going with the stock Mazda setup in the front. I can upgrade later if I need, but with the disc brakes in the rear versus drum brakes I might just be fine.

Awesome build in that thread by the way.
