72 SIII 88'
Fitted brand NEW brake shoes and drums all round . New fromt cylinders.
Bled system - nice and firm.
Test drive and the pedal suddenly has massive travel ..air? Pumping firms it up only for that braking episode.
Rebleed and check for leaks...no air, no leaks. Servo new (a few months back).
Test drive and the pedal goes way down again....repeat...
So when engine off, brakes really nice and tight. Do not even go soft over night. No visible leaks. When sitting with engine idling, brakes appear nice and firm, BUT when I drive, and apply the brakes they travel way down. They stop the truck pretty well, but this is not how it should be.
Of course brakes did not have this issue before I changed them out...
Many thanks for any comments!
