Today I once again tried to fix the low pedal issue on the 67 DeVille´s brakes. I recently replaced the booster and master cylinder and had a low pedal problem then. The brakes worked fine, but the pedal travel was way too long. I first suspected air in the lines, but we really thoroughly bleed the whole system multiple times. I then thought that the push rod of the new master cylinder might need some adjustment, until I found out that the Delco Moraine boosters are not adjustable, whereas - the also used - Bendix boosters had an adjustable rod.
As I replaced the complete front end including the entire front brakes last year, I did not think that the drum brakes might only need a simple re-adjustment. As it turned out the front brakes were out of the range where the star-wheel can adjust itself while driving the car backwards and applying the brakes.
I now adjusted the front brakes pretty tightly and the pedal is now pretty firm again. I hope it will stay like this. If not - there must be something wrong with the automatic self adjuster, but I´m very optimistic that the problem is now solved. I also gave the rear drums a check - they turned out pretty fine. I just wished the DeVille had front disc brakes like my 67 Eldorado...
