The Stovebolt Site Forums The Shop Area Driveline Parking Brake

Replaced some brake components in my 53 3100 (ss lines, master cylinder, wheel cylinders, etc.) Parking brake pedal does not stay depressed, replaced rubber grommet under dash, still no go. What am I missing? Thanks

pump truck paul,

I have enclosed a nice picture of the parking brake. The little item called the 'brake lock' has to have rather sharp edges where the pedal arm passes through it. These sharp edges bite into the arm and hold it, which holds the parking brake ON!

See if the picture helps and take a look at the condition of this 'brake lock'. Good luck.

I am not disagreeing with Stuart exactly. It helps if the hole in the pedal lock is still mostly round, and the edges are clean.
I think this is what Stuart ment. If not please feel free to correct me. Also this whole assembly needs the correct tension to work properly. Even after adjusting everything on my 52 I had to tweak the pedal lock just a bit to get it to work like a champ. As a note while not shown in the drawing there should a small spring between the lock bar and the floorboard that rides on the lock shaft.

Thanks. I'll disassemble parking brake,clean it up real good and see if I can figure it out.
