Replaced all rear brake components and flushed the fluid. I'd forgotten what a PIA it is and it took me a lot longer than I planned. Pedal feels a bit firmer even though I still haven't adjusted them up properly yet, foot brake is still low. The fluid had gone a funky shade of green. No more sticking caliper, and no more squeaks I hope.

Working on wife’s econo-car which hits the wall of the garage. Randomly shuts off when turning right and has a fuel pump DTC. I told her to just make left turns.

I’m sure there’s a correlation somewhere, but I’m used to working on my 400s and don’t know where anything is on it so it isn’t fun anymore.

Just changed my thermostat as I didn't like the way it was operating. Would hit 200-210 depending on how I was driving, and then drop down to 170-180 and stay there. I had replaced the original with an aftermarket about 5 years ago along with an aluminum 3 pass rad, water pump etc. I decided to get a OEM Delco rated at 198 supposedly. But now operating temp on my gauge with the new 198 stat is showing 160. At least it seems to be steady at 160. But now I'm really confused. Pretty obvious the gauge is out but... Is this one bad? Was I way too hot before? It's not what I was expecting to happen.
