i have a 68 mustang with rear drum brakes and i replaced the drums and brake pads and the rear right drum is scraping when i drive, when i took of the drum i found some shaving inside i dont what is scrapping against or why 10"x2" drum and 1 3/4" pads NEED HELP

 

My guess iseither it needsadjusted (obviously) or maybe you had 9" brakes instead of 10".

 

are youtalking about the drums or the brake pads?but the rear left spins with out any binding

 

Adjust the brakes until they are too loose, then on a deserted street, get going in reverse and slam on the brakes. Do this a couple or three times and your brakes should be adjusted.

However, if you have 10x2 drums and 10x1 3/4 pads, get the right parts and start over.

 

I was refering to the drums.
Yourpassenger-rear drum is rubbing while your driver-side drum is not, right? Hmmm ... My strongest guess is that your drum is is rubbing against your rim. How much clearance is there between your drum and rim? Whats the backspacing on your rims?

If I were in your shoes, id put the car securely up on jackstands, throw it in drive, and see WTH is going on back there.

Keeps us posted.

Hawkins, How does a drum rub against a rim?If the tire goes on, there's room between the drum and the rim and since the drum and the rim are attached with lug nuts they spin together.

 

You need to shoot us a photo. the problem could be as simple as the the brake shoes ( pads are used with disk brakes, fyi) are incorrect for the car or the hold down springs and pins are too tall. Since the problem didn't happen with the previous shoes it's most likely that the shoes themselves arethe root cause.

 

Depends on the rims. I purchased a Ford Probe not too long ago as a DD which had 18" verde rims. The rims werent universal and shouldnt have been jammed on a Probe in the first place. Afterwards i realized that therear tires werentcorrectly level with the ground so i took one of them off to see what the problem was.As soonas irolled the tire off i notced that theinsideeach "leg"of the rim were chaf'ed. I honestly dont know how the hell he didnt notice it after putting them on at first...it was a good 1/4 in. chafe'd on all 10 legs of the rim(kinda like spokes only thicker)....FYI

Just another day in my shoes....

i replaced the drums and brake shoes and it looks like is scrapping inside the drums, if i had a bad axle bearing would this throw off the rotation and causing it to scrape inside the drum?

 

If you had a bad axle bearing there'd be oil all over the place and chances are very slim that all of a sudden the bearing's axial clearance would be increased. Its either the drum is not machined deep enough to accept your shoes or the shoes are incorrect. (I've seen both over the years)
