Drum Brakes Locking On All 4 Wheels
Hi, I have a 1967 gto, 4 wheel power drum brakes. New master cylinder, pads and freshly bled. Went for a ride today, got gas and went to leave and I could feel a lot of drag like somebody was pulling on my bumper. The brake pedal was super hard to push, I got maybe a 1/4 inch before I could depress it no further.
I Hobbled home and all 4 Wheels were smoking by the time I got to my garage. I waited 10 minutes for it to cool off and then they worked fine.
What could cause this ?
