My '55 352 runs just fine on 87 Unleaded. Previous owner of 10-plus years used the same.

I doubt the equipment installed is incorrect. I've put about 2000 miles on the car with no problems and the previous owner was driving it as well. Unless I missed something, the car was braking fine and then starting grinding out of the blue. That is why I pulled the drums expecting to find something overly worn or broken. All I found was the rear shoe with a rub mark and those small rivets (I think they're rivets...) on the drum rubbed to a shine.

That said, I'll take some measurements just in case.

The grinding noise occurs while decelerating in a straight line from speeds of 25-30mph or greater. I can't say if it occurs while turning as I'm usually under those speeds when entering a turn.

As for my comment vis-a-vis the hardware, I was referring to just the brake hardware. I only removed the rear brake drums to inspect the shoes and springs after the grinding noise started. After seeing that the shoes were not visibly worn, the retaining hardware was intact and the drum braking surface was not scored, I put everything back together and adjusted the brakes per the manual. I hoped that the shoes simply needed adjusted and that a bit too much travel was allowing the shoe to move outward and contact the inner face of the drum. Unfortunately, the noise never changed although braking performance improved a bit.

I can identify the two points of contact from where the sound is emanating: one, is a relatively small shiny spot on the steel edge of the secondary shoe; and, two, the heads of the little rivets that are found along the circumference of the drum "hat" are polished to a shine. I just don't know what's leading to the contact.

Ignorance and misery often go hand in hand, or so I've been told.

After looking at the washers again, I decided to just replace them with two new SAE grade 8 washers. This, along with your advice to draw the nut tight with an impact wrench, lower the car and then tighten to the next open castellation, took care of the cotter pin alignment issue. I did double check the torque once aligned and I was north of 250ft-lbs on each nut.

Unfortunately, while the brakes stop smoothly and straight, the left rear secondary shoe is still grinding on the inside of the "hat" of the drum. I had thought that a maintenance adjustment of the rear shoes would eliminate this, but I'm now at a bit of a loss. Could the hold-down springs be allowing the shoe to creep outboard on higher-speed (30mph and up) stops or should I be looking somewhere else? (The rear hardware all looked to be in good shape but it's age is unknown).

After reading through my '55 service manual, I still have a couple of (rookie) questions about reinstalling the rear drums on the axle shafts.

First, is there a recommended practice for keeping the drum from rotating while torquing? I chose to use a wedge between the frame and the wheel locating stud on the drum to keep things in place. The passenger's side tightened 'OK' with this method but, frankly, I was a bit concerned about the leverage I was applying to the wedge (a steel bar). On the driver's side the wheel locating stud bent at about 225 ft-lbs of torque.

Second, neither nut lined up with its cotter pin hole. On the passenger's side I have a castellation partially over the cotter pin hole at 200 ft-lbs. and directly over the cotter pin hole at 270 ft-lbs. On the driver's side, the cotter pin hole is just barely clear at 200 ft-lbs. and partially obstructed at 225 ft-lbs. Is dressing the nut worth the effort or should I be looking for new grade 8 washers? If it makes a difference, the original washers appear be a bit less than dead flat.

Third, when re-torquing the axle-nuts at 100-miles post-install, can I use the weight of the car on the installed tire-wheel ass'y to keep the axle from turning, or should I re-torque the nuts with the car off the ground?

Last, regarding the bent wheel locating stud on the drum, should I be concerned about its long-term viability given that I had to coerce it back to position with a few taps of a hammer?

As context to the above questions, my car is 1955 Clipper Constellation that is driven regularly and is in reliable mechanical condition. I pulled the drums to locate a slight grinding noise that would arise under hard braking conditions. I found that the secondary shoe was just barely contacting the inner face of the drum which I believe can be corrected with a brake shoe adjustment.

I've done plenty of drum brake jobs in the past but they've all been on cars with axle flanges so this certainly has been a learning experience (and quite the physical workout!) As such, I apologize if these questions seem overly basic. I did read through multiple threads using the search tool, but I could find no reference to these particular issues.

Thanks in advance,
Scott G.

Sold for $120,000. Not too shabby.

You might have better luck asking over at the HAMB. There's lots of creative DIYers and pro painters over there that I'm sure have dealt with the very same issue you're facing.

Good luck.

By the way....there's nothing wrong shooting a solid color in BC/CC. I used it on a red '68 Mustang and was very pleased with the application and the result.

I've attended auctions at Milestone in the past and their consignments are generally high quality and tend to generate top dollar. I doubt too many flippers will have success here.

There's an interesting auction scheduled for October 15 near Cleveland, Ohio that includes a nice 14th Series Packard Twelve coupe and miscellaneous Packard parts and accessories. The listing and a link to the catalog can be found at auctionzip.com.

How can I edit (or have deleted) one of my entries into the parts cross-reference? I listed an incorrect part number and want to make sure it doesn't live online forever.

Thanks.
