datsunaholic Posted February 12, 2011 Report Share Posted February 12, 2011 SO, after realizing that the brakes have been badly neglected on my '72 510 Wagon, I set out before the rains hit to change the brakes. Unfortunately I haven't received all the parts (rear shoes, cylinders) but I could at least replace the front pads and inspect the rears- at a minimum hope the drums come off. Was somewhat amused by the "wedge" shaped front pads, but that's normal according to the Haynes manual. Being that they were worn clear to the backing plates I had to refer to the book to see which way they went on... then noticed the pads all had "RH" or "LH" written on them. So, easy enough. Very easy to change, actually. So, to the rear. The rear of the car wanted to jump out of it's tires every time I hit the brakes or applied the parking brake when moving last time I tried to drive it, so I expected broken springs or a failed drum. So, pulled the drum. The driver's side drum came off easy enough with the jacking bolt- didn't have to back off the adjuster or anything. But this is what I found inside: Something's missing. Details in next post. Quote Link to comment
metalmonkey47 Posted February 12, 2011 Report Share Posted February 12, 2011 You have no rear brakes Scary. I'm scared to pull my drums tomorrow to inspect. Good news is,I got the new drums, hardware, shoes etc. Keep us posted. Quote Link to comment
datzenmike Posted February 12, 2011 Report Share Posted February 12, 2011 Ha haha. Sometimes brakes can be so surprising. Check this rotor.. You would think the driver would noticed but from experience this isn't always so. Our old company Ford van had a flat tire and when we removed it the front pads were worn away and were metal to metal. When we took it in for replacement the guy tried to give me shit for driving it like that. Doug, that van braked perfectly, smoothly and evenly. There was no indication there was a problem. My '74 710 also has the angled pads. . Quote Link to comment
jefe de jefes Posted February 12, 2011 Report Share Posted February 12, 2011 Evaporated!? Where'd it go? Quote Link to comment
datsunaholic Posted February 12, 2011 Author Report Share Posted February 12, 2011 So, when I pulled the drum I actually had parts fall out. Yep. Completely debonded. Had to be pretty recent, because they aren't broken. A little wear on the edge where they hit the face of the drum. The drum itself is perfectly fine. Quote Link to comment
datzenmike Posted February 13, 2011 Report Share Posted February 13, 2011 My dad's old '90 Sundance has 25K miles on it and the original rear brakes and they de-laminated just like that. Age I guess.???The pisser was that they were hardly worn down. Quote Link to comment

SHAMUS'WAGON Posted February 13, 2011 Report Share Posted February 13, 2011 Those are fiiiine I had a customer bring in a rotor that looked like that. He wanted to know if we could resurface it. When I told him there was no way in hell we could even touch it. He said, "It just started making noise yesterday." Quote Link to comment
nismo dr Posted February 13, 2011 Report Share Posted February 13, 2011 I had a full size doge truck get towed in last week, the parking brake shoes in the left rear rotor had come off just like that, only they got wedged in there and locked up the wheel. Quote Link to comment

That's how the Sundance was if you backed up it would stop and the rear would lift up like climbing a curb. The drum came off easily and the linings dropped out, wtf? Quote Link to comment
nismo dr Posted February 13, 2011 Report Share Posted February 13, 2011 it took me a while to get the rotor off, I had to beat it off ( :lol: ) with a hammer Quote Link to comment
thisismatt Posted February 13, 2011 Report Share Posted February 13, 2011 I had a customer bring in a rotor that looked like that. He wanted to know if we could resurface it. When I told him there was no way in hell we could even touch it. He said, "It just started making noise yesterday." I had to flag down a BMW SUV on the freeway because it was driving at 65mph with a flat rear tire, almost completely shredded and throwing sparks and smoke. 5 guys got out and I pointed to the rear wheel and asked if they had noticed it. Their response was something like "Oh, uhh, yeah, we just started hearing something." I'd been behind them for about a mile and could smell the burning rubber before I ever saw them.

metalmonkey47 Posted February 13, 2011 Report Share Posted February 13, 2011 Hey mike, how would you pull rusted on drums without a drum puller? I gotta do mine tomorrow. Quote Link to comment
datzenmike Posted February 13, 2011 Report Share Posted February 13, 2011 Loosen off the adjuster and the e brake to get the shoes retracted as far as possible. Now take a look on the drum just outside the stud circle, you'll see two small threaded holes one across from the other. Just get two small bolts (10mm head maybe) and tighten them in. They will bottom on the axle and if you keep tightening them in evenly it will pull the drum off towards you. This may be all it takes to loosen the grip and you can smack it a few times to loosen further. Have a care, because if the shoes are tightly gripping the drum it will tear them off with the drum including the anti rattle spring and parts. Warning: Get a can of brake cleaner and some rags. As soon as you can, spray all the loose dust off the drum, backing plate and old shoes and collect on a rag. Put the old shoes and the rags in a plastic bag and dispose of. Avoid stirring up any dust and really avoid breathing it. 1 Quote Link to comment

Anybody ever watch the movie/ documentary " Yank Tanks " because of USA embargo the Cubans make parts for the American cars imported there in the 50s. In the movie they talk to this old dude that makes brake shoes out of epoxy and asbestos in a oven on his back porch...they interview a bunch of guys like him..pretty awesome movie ,I had my friend get it through Netflix Quote Link to comment
