I may be retracting my method of rtving the brake slider bolt boot edges as this may cause the brakes to scrape the rotor. I'm gonna find out tonight after I remove the RTV cause braking is still not satisfactory.
Very sad too cause this is the first time I've driven in the car in I don't know how long. Oh well. Was a test run though. If removing the RTV (which was my own idea) solves it then I know for sure the slider bolts need air as they squeeze and release.
However since I know ALL 4 brakes were in perfect sliding condition before I took it out for a test drive I'm now suspect of the last brake system item I have not replaced.
The proportioning valve. It would explain insufficient braking power and tonight why the car was pulling hard left.
