I recently did my back brakes on my 71 Nova and the new drums had a stamped outline for the hole on the side of the drum so I used a dremel and small grinding stone to cut out the slot to gain access to the adjuster wheel. That means the tire has to be off to adjust the brakes which makes it difficult to get the right amount of drag when setting the brakes. My older Ford truck has the slot at the base of the backing plate with a rubber grommet covering the slot. I used a bar between the wheels studs to turn the drum to check for drag but careful not to damage the threads on the wheel studs. That's my brother cutting out one of the slots on the drum

Haven't come across that one yet because I had the tranny out to replace the clutch and did the oil change then . Realized when the tranny was out it made some noises I didn't like so had it rebuilt. It's the original M21 4 speed. Also had the shifter mechanism rebuilt. It was not the original muncie shifter it was a hurst which people on SNS recommended I retain .

There is normally a slot in the backing plate for the rear brakes... that is located behind where the star adjuster wheel would be located. This slot in the backing plate usually has a rubber plug in it that needs to be removed so the star wheel can be turned to adjust your brake shoes.

If your backing plates does not have this slot, I would just remove the rear tires and the rear drums... and adjust the star wheel so the brake shoes slightly drag on the drum when installed over the brake shoes and turned.

When I rebuilt my rear it did not have a hole or even a knockout so you could. I did what RifRaf suggested. I had to take the drum off a couple times to get it right but the auto adjusters should be able to take over once you got it ball-parked.

i found one of those drum adjuster tools at a rummage sale a few years back. the young kid had it in with some junky tools for sale. i picked it out an asked a price he said a quarter, ill take it. he asked what it was for as he had never seen one before. plus it was chrome how could i go wrong. well it works perfect with a little duct tape on it for removing the center caps on a rally wheel. thats my tip of the day. enjoy the cruise, when you can.

Hi are they 9 inch drums? If they are you may have to knock out the opening. It should be outlined/perforated just not open from the factory. I never understood why they did that. It can also have a spot on the drum same outline as the backing plate. They make a tool to measure the shoes with the drums. You should be able to get them close go a couple of clicks at a time till there is a little drag on the drum. I hope this helps

Yea I realize that. Just looking for any dumb excuse to post a pic of the tranny.
Hey John ........ you can also "post your pictures "direct on to SNS" ....... (not using the 'attachment' ).
(just click on the 'camera' - - #1 = paper clip - - #2 = chain links - - #3 = smiley face - -
# 4 === That's the camera).
SNS new site - does make posting up pictures very easy , now.

............. jim

Hi just curious about something. The shoes are 2 different lengths the short she goes in the front. A quick look at the pics you put up although not seeing both shoes completely, to me they look backwards. let me know. BTW glad the backing plate holes worked out.

you could be right, I replaced them the way they were on there, which was probably wrong. Im also missing one drum and the one I have i assume should be for a front drum because it has no ribs. i already left the shop for today, but would you have a pic of how each side should be?

neil63ss is right, primary shoe is the shorter shoe and always goes towards the front of the vehicle. The secondary shoe is the longer one and is always towards the rear of the vehicle. The best way for me to remember is the shoe closest to the adjusting screw star is always the secondary, longer shoe.

About your comment about the drums being ribbed. Those are cooling fins and are better drums. Depending on the year 62 & 63 get what you can. 64 on up should be no problem finding them. It does make a difference. If you don't have if a booster really helps. I never asked what year is your car?
