Removing Rear Brake Rotor '79 SC

[NashvilleGW]

So I decided last week to finally fix my broken hand brake cable. I've got all the parts and a couple hours to kill....

First....off with the tire...perfecto...no problem.
Second....out with the brake pads...got it.
Next...off with the caliper. Hmm how do I get this 1/2" ratchet and 19mm socket back there??...after searching the garage, finally a 3/8"ratchet alternative and a lot of effort and foul language...off it comes. Dang-it, I can add a new banjo brake line to the parts list. I'm pretty sure it's not reusable after I twisted and contorted it...

Now let's look at the caliper....hmmm...wow...time for a rebuild....man this project is getting longer....time to go to the parts list at pelican parts and add this to the list too.....

OK...time to get this rotor off...HUH?? Flat Head Retention Bolts?? What was Hans thinking when he assembled this in Stuttgart 30 years ago? I can't get these blasted things out. The more I try...the more little metal shaves get married to my screwdriver....soaked in Deep Creep penetrating oil...and still not budging....

Help....How do I get these things out? Any secrets that don't require drilling?

Hey Nashville,
I used PB B'laster I got at Lowe's and let it sit overnight.
And the biggest flat-head that will work.
Replace them with these.

Impact screwdriver. If you don't have one then you might have to spray the penetrating oil, tap the screw head to get the vibrations to deliver the oil in deep. Patience and keep at it.

You can bang them with a small flat chisel to break the rust holding them in.
Place the chisel tip in the slot and give it a couple of good whacks.
Then use the biggest screw driver you have to break then loose.

You can buy a "impact screw driver". You bang on the back and it rotates automatically when you hit it.
You can switch the direction from clock wise to anti clock wise.
I've seen them with multiple tip sizes and styles... Philips head and straight blade.

There's no elegant way to do this....

you can just drill it out. In all reality, you dont even need it when you reinstall the rotors. I still have mine on though, since i did not have any issues getting them off. The impact screwdriver will get you out of all sorts of trouble. i highly recommend you get one.

your first mistake was "having a couple of hours." Nothing can be done on this car with a couple of hours, other than an oil change, and only if you don't overfill it.

1. impact driver
2. heat it cherry red with a MAPP gas torch
3. Drill

That will take a whole day.

I little heat will go a long way here after you've tried the pentrating oil.

Plenty can be done on the car in a couple hours...just no project can be completed...with a 1yr old....the only time I have to work on the car is during her nap-time. As soon as she's asleep, I sprint to the garage. It's amazing how efficient you can make your project time, when the clock is ticking!!! This will last until, of coarse, she's old enough to start handing me wrenches...

I appreciate everyones reccommendation. I'll swing by Sears to pick up the impact screwdriver on the way home from filling my belly w/ Turkey....

Happy Thanksgiving to all of you.

Thanks

NashvilleGW welcome to the board. +1 Impact screw driver, they are not very expensive and make the removal easy

+10 on the impact screwdriver. It turned what could have been a long painful exercise into minutes of work. Frozen screws turned with two swings of the hammer. Make sure you use plenty of neverseize and new screws when you replace them.
