Hi,
I have a 1954 Bel air and am curious as to how the pedal should feel.
This being my first car with the brake pedal coming out of the floor (outside of VWs) I was curious if the pedal itself should swivel as it is being pushed down. Mine seems to do this. The brakes are in great shape but I am questioning the pedal action.
Thanks!

The pedal is solid on the rod.

Mine is solid on the rod but when I push it, it feels like just the pedal swivels over then pushes down. Something must be going on underneath. I will have a close look at it tomorrow.

My best guess is that the bushing in the pivot hole in the master cylinder is worn.

Thank you. I got under there this morning and the brake pedal rod was barely connected to the rod that goes to the master cylinder. I tightened it up with lock washer and it is good now.

Make sure that you have the rod correctly adjusted. When the pedal returns to the up position there needs to be a very small amount of clearance between the end of the rod and the seat in the piston in the master cylinder.
This ensures that the piston returns to the home position and opens the small hole to let the brake fluid flow back to the reservoir. That fluid is pushed back by the return springs on the shoes.
Otherwise there could be residual pressure in the system and the shoes will drag on the drums.
