Brake goof up question
 

So, I was working on a the brakes on a 72 911 they are 78 SC brakes and I accidentally put the inner brake pad on the driver side in backwards, as in metal side against the rotor... and didn't notice. The strange thing is the brakes stayed soft until the pad was found and switched. How is that possible? It should not have affected the pedal stiffness right...

Any of you experts have any thoughts?

You should be able to realize I am perplexed by my willingness to admit such a bone head move.

Thanks in advance for your comments.

I would say that the metal plate didn't fit 100% against the rotor and was flexing, giving you a bit of flex in the system. The piston could also have been compressing the pad material.

Anybody that says they've never made a bone head move is a liar.

you could start a whole thread with bonehead moves .. il chime in with Blew up my perfectly good airbox ...

as to your question , did things stiffen up when you flipped the pad around ? if so ill go with backing pad not flat against rotor flexing and pushing back fluid

i have done the brake pad thing and so has my brother.
i dont think either one of got as far as driving it.

Yep, the brake system stiffened up as soon as the pad was flipped.
I like the binding theory as it explains the soft pedal.
Thanks, its mobile again...

I've done the same thing. It's easy to do with 911 pads as they are fairly small and square.

By the way, your car does not look Delphi Green to me...but looks very nice (like the duck).

Thanks Tidybuoy!

Nice observation, my first Porsche was a 1974 914 2.0 Delphi green... miss that car!
