Kevin helped me flush the front brakes last weekend, and I did the rears last night. It improved the brake feel slightly, but the pedal still slowly sinks to the floor. Need to figure out why. Also, I need to inspect the pads and rotors.
I jumpered the low pressure side switch (on the dryer cylinder) and that made the air conditioning compressor come on. It appears the system is undercharged. I didn’t have enough refrigerant to fix it, but I’ve got more on order from Amazon.
