Are the front brake drums the same as the rear ones? I had my garage install new drums on the car and now at 25-35 mph the car shakes like the front wheels are going to fall off. Car has new brakes all around and car was fine .Went back and had the new drums installed on rear and car was fine and then went back to get the front ones installed and thats when started, The steering wheels shakes and feels like the front tires are going to come off. the hubs are flat on drum and it is not hitting anything they spin free.Thanks
Front and rear drums are the same. Aftermarket new drums from China are known to be crap... vibration issues, and do not have alignment tabs or recessed weights like original. Below is my post in the For Sale forum for drums. I had 10 turned and down to 2 right now but putting 2 more in to be turned Monday. If want turned originals email me at firstname.lastname@example.org.
Here is the ad:
Turned 1960-65 (& later) Rear Wheel Drums - $75 each <-- Click for More Pictures
The aftermarket drums are not cast correctly and will not mount up correctly and have seen a spike demand for VG original drums. I have cleaned, painted, & turned 10 of my best rear drums. These are original drums pulled from 1963/64 Cadillacs and have the correct recessed weights and 3 alignment tabs that allow the stock wheel (rim) to mount up to them.
These are the same drums used on the front, minus the front hubs. I also sell the drums unturned for $55 each. MPB lists these as fitting all 1960-65 Exc CC, 66-69 CC (with spacers), 67-69 Exc Eldo, 70-74 except Eldo.
Price is $75 each. Email me at email@example.com
Thanks again for your help and output. I should know better than trying to use China made junk in a Vintage Cadillac.Driving home at 25 mph with the steering wheel shaking and thinking the front wheels are going to fall is not fun at all. I will start with trying to find someone who sells raybestos brakes shoes and try and turn my old drums. Thank you for all your help.........Mark
I had —Exactly —the very same experience you are having ——after the very first time I had my front brakes replaced by a shop as I have done my own brakes on all my cars my entire life except this time as I had the entire car gone over in 2006 in Florida before my retirement
The experience is —extremely unnerving and feels like the front of the car —-is violently about to fall off —and cannot imagine how this could be happening for any reason ( hard to believe )
It took me 6 months to figure out that it was the brake shoe friction material that was the problem and that was —-the last thing I thought as they were just replaced and repaired adding to the problem of trouble shooting and correcting the problem
Some brake shoe linings cannot handle the heat these very large 12 inch drums produce which are very large for any car
You should find your shoe linings to have a smooth shinny polished appearance and even cracked in places caused by heat ( called brake glazing ) that prevents the lining from grabbing the drum as they should be
My solution was to replace my new brake shoes with Raybestos brake shoes that do have a superior friction material and are cut to the drums shape by Raybestos the same way the local auto store machine shops did in there back room machine shops back in the day when our cars were new ( no one else does that today )
Only used this brand of brake parts for over 50 years
If you find that your brake drums are part of your issue do go with replacement front brake drums from Jason as any new replacement drums are the newer free floating type drum that requires a good deal of extra work having to remove the front hub from the front brake drum assembly and replacing all the lug nut with longer ones there as well ( a lot more work ) but they do work well once done
All 4 brake drums use the same brake shoes
In my quest to find my problem I did new replacement front drums from Auto Zone but that was some time in 2006 after getting the car back from the shop that gave me back my car with the condition you are explaining ( crazy shit ! ) and they worked great after the above extra work I explained I did above
Replacing the drums and bearings was not the issue but the brake shoe material —was it
I have posted this a number of times over the years and the info is in this sites library —Search
When you get the brakes right on our Cadillacs they will stop on a dime and with no need to be replacing them with front discs and my Radial tire help improve that some ( never any brake fade or stoping issues in 56 years )
Replacing your brake linings and you front drums if needed will solve you current issue but basically redoing the brake job just done—- which is a major PITA
Raybestos does make the newer ( free floating ) drums for our Cadillacs if that is the direction you may choose or need to go
The problem with the bad new replacement drums is the location of there balance weights that prevents the tire rim from sitting flush on the brake drum when installing the tire rim from my understanding
That is the scoop !
Sorry that the news is not better than it is in this case
Thanks for your input on this. I had the bad shaking of the steering wheel has soon as they put those ac delco china drums on .The day before we put 2 more on the rear of the car and drove the car for 50 miles with no problems. When i first got the back with napa brake shoes all around and the original drums not turned the car stopped good then i put some miles on it and the front brakes started to shake when they would get hot. So i thought by getting new drums on the front would fix that problem instead of turning the old ones, Well i guess in didnt think it would get worse.Well i will be looking at where to find some raybestos front brake shoes and try to get my old drums turned.Thanks again
Try Rock auto for the shoes
