I was up late Tuesday night taking apart the well crusted rear brakes on the new to me 31 year old Mercedes Benz 300D Turbodiesel. It was a slower than usual process as the quality brakes were nearly down to metal to metal contact and so will require new rotor/drums as well as hoses and pads. No big complication, except that getting the assemblies apart took time. I took it slow to be able to reuse the pins and springs and used a little more liquid wrench and wire brushing rather than brute force. What is nice though is that all the parts are higher quality than I’m use too and they can be cleaned up to last another 30 years … not sure about the cylinder seals, but the are not leaking at the moment.
While I had the rear tires off, I gave the aluminum wheels a soak and scrub brushing. They are cleaning up nicely but show the same scrapes and scuffs that our previous MB 560SEL had back in the 1990s. I’m not sure if it is worth the time and effort to sand them smooth in order to repaint?
One minor detail is that one of the rear lug bolts had been previously stripped out of the hub and tacked in place with some caulk/sealant. Hmm, at least I have the lug bolt. Now to decide if a Helicoil is going to work for a lug bolt or if I should weld and re-tap?
