from right rear wheel area.
not as bad going downhill,
but worse when turning left
in a curve........wheel bearing?
PARKED till fixed! boohoo .......zimmmy
 
Brake drum shoes on backplate rubbing / loose wheel / could be a bearing going downhill seems load related
 
i havent done the rear brakes ...yet!
i do get loose lugs sometimes, so im
up on that...
i havent got to investigate yet..
im pretty sure its gonna cost $ ! doh!!! ...z
 
Seem like you and I are following the same path. Mine is torn apart for hub seals on the back, got the kit from VB which includes bearings but they told me in that thread the seldom fail. I had oil all over both my rear brakes rendering them useless. I also redid my master cylinder yesterday, this time with a hone.
 
Brake drum shoes on backplate rubbing / loose wheel. Preaty much with Jim on this. Should not cost anything to fix when you find it.
 
i hope ur right...
i REALLY didnt wanna work
on the car today,
but im gonna go look underneath
with a light.....z
 
I had a similar issue and don't know if it is the same. My backing plates were rubbing the drums on hard turns. Fresh paint told the story. Wacked the backing plates back a bit and problem solved.
 
Zimmy, See your rear brakes weren't even working. Soaked in fluid from rear end or else you've got a leaky wheel cylinder. Gotta figure out which one. Is it Brake Fluid or 90W Gear oil. While you are in there might as well order and replace the wheel cylinder as you are going to need to replace the brake shoes. A leaky hub can be cleaned up and sealed with some RTV. You'll need to pull the axle but only a few bolts and it all comes off and axle slides out.
 
i didnt figure the brakes were working...
i have new front disk though....
i dont have a problem with leaking
brakes, so i believe it 90W from the lump...
the rest comes out at the shaft connection of course!
dont forget,...it was making a grindin sound,
kinda like when ur throw out bearing is goin out....z
 
Zimmy, new O ring seals can be procured from the hardware or the local auto parts place for cheep. Take an old one for sizeing. New gasket can be made from a brown paper bag.

Now for the brake shoes. In a bucket of gas for a bit and clean em up good.

While all is out check for the brake drum rubbing on the backplate..
 
Gas works OK for cleaning up the shoes, but I prefer to use brake-cleaner for a more thorough cleaning than even gas does!
 
No, no, no... I have to disagree here. If the brake pad material has been contaminated, throw them out. There is no good way to draw oil out of brake pad material, and they will re-contaminate your drum surface. Brake cleaner will clean oil off non-porous metal surfaces, not fibrous and porous brake pad material.

That $12 part is NOT the place to try to save a few bucks. Cheap out on anything except brakes and steering - they are the two things that you cannot afford to have fail.

If it means 3 extra days while you wait for parts... well, that's three days to pull & clean the axles, degrease & repaint the backing plates, make up new gaskets, remove & clean & repack the bearings. Maybe have your drums machined, or R&R the fluid in your rear shocks.
 
:iagree: Unless it is an emergency never try and clean oil or brake fluid off brake linings .as they are porous they will soak up the fluid ,they will look clean but when they are used fluid will be squeezed to the surface again rendering them useless.cheap enough to replace knowing they are going to work
 
I'm gonna side with Duncan. The brake lining is contaminated. It's porous and has LUBRICANT in it now. Gas soaking just makes it a "lighter oil" than 90W. If there's a good truck brake shop in the area, go show 'em your "cute li'l brake shoes" and after they're done laughing at 'em, they should be able to reline 'em "while you wait" if you're in a rush. Otherwise, hit NAPA for a new set.
 
Upon reflection, I would disagree with myself also!!! Duncan and Doc. are absolutely correct!!! :blush: (Very dumb advice!!! Mechanics 101!) :wall:
 
To each his own. Zimmy is trying to get his car on the road for cheep. I'm sure he would replace the shoes when funds become available.
 
I've been guilty of washing brake shoes with lacquer thinner and tossing them in a bucket of oil dry for a week and then reusing them. I've always gone back and put new ones on later, but I can honestly say that I've never noticed any difference. The parking brake could still lock up the rear tires. It may all depend on the type of material that the lining is made from. But it may be prudent to use the cleaned up shoes until you are sure the oil leak has been stopped. ... that said... I'm sure that new brake shoes are a safer option.
