I had my factory correct part number master cylinder resleeved and rebuilt.
(Power Brakes) I also had the brake booster rebuilt, yet I have the following symptom which I need help with.
The car is only driven on sunny days and weekends and often sits for extended periods. When first leaving the driveway, the pedal goes to the floor before the car will stop and only after driving for several minutes(or miles) will the pedal gradually get stiffer and stiffer until finally it is perfect and the brakes stop the car perfectly every time. It remains perfect for as long and as often as I drive the car that day and then the problem manifests itself again the next week or two when I drive it again.
I have bled all the brakes several times and after initial bleeding, no more air was expelled. Also, when this happens, repeated pumping of the brakes does not cure the problem so I do not think it is air in the system.
Could it be that something inside the master cylinder needs to warm up and expand to work properly. I did not have this problem prior to having the master cylinder rebuilt and resleeved. I want to keep my present master cylinder as it has all the correct part numbers and markings for my stock L79 68.
Thank you for any thoughts or suggestions,
Kurt
