Hi,
Got my 427 -69 back on the wheels yesterday and drove my first 100 feet on the road. Had to stop and go back, it was too much dust on the road after the winter, and then I noticed that my brake pedal was a bit slow to return after beeing depressed. I could feel the hesitation of the brakes for 1 second before they let go of the discs.
I have a totally rock hard pedal, and it is like slamming in to a brick wall when i apply the brake pedal.
The master cylinder and brake booster is brand new, from a well known supplier, and the quality seemed greate. The master cyl. was licensed under GM according to the box, if that is a quality sign theese days...
What can be wrong? The pedal takes just over 1 second to return from fully depressed with the engine running.
Is the internal proportioning valve inside the booster (do not know the exact name of it) out of order or can the booster be a bit slow after being stored in the box for a year and a half before assembly?
Can I hope for this to get better if I drive a bit more?
Regards, Daniel
