Help from the experts, I need to find a new or working Support plate for my rear drum brake for my 1958 Plymouth Belvedere and 2 sets of BRAKE SHOES AND LINING ASSEMBLIES,
the lower rear rectangle slider on the support plate is stuck and doesn't move freely anymore it bends the brake shoes, that's why my rear brakes keep locking up, in the 3rd photo you
can see how the lower hole isn't round anymore like the right shoe and in the 4th photo the left shoe is twisted and jamming, is this the correct BRAKE SHOE AND LINING ASSEMBLY from

https://www.oldmoparts.com/parts-service-brakes.aspx from Andy Bernbaum....

Thanks any help would be really appreciated and by the way I'm in Australia...Cheers

Drums 11"
Shoes 2"

I for one are a bit confused by your text and photo/diagrams. Most of them show center plane/total contact brakes in which the shoes slide/pivot between two plates without a particular pivot point yet it seems (to me) that you are concerned about a pivot bolt which is for a different brake system. The Bernbaum diagram is NOT centerplane.

The lower triangle on the brake shoes just rests/pivots in the support plate. This should normally don't give any problems, so, I'm thinking that you have the wrong brake cylinders or wrong return springs (or wrong position of the return springs)

Did you adjust the brake shoes according the instructions in the fsm? Front adjuster in the direction the Wheel rotatates in forward motion, rear adjuster in the direction the Wheel rotates in rearward motion...…….

Ron on the Forward Look Network Facebook pages has worked out
What the issue might be, my support plate is from a 1959 Plymouth rear
Brakes completely different shape to to a 1958 Rear drum support Plate

What do guys think? I’ll be passing this onto my Mechanic, because he
Has the car, Sven do think that the support plate might be the issue?

I’ll see if I can get photos of the other parts as well, really appreciate your
Expertise and input from both of you...cheers

The photo below is my support plate and the one next to it is a photo of a friend’s
Rear 58 Plymouth

I don't think that the support plate is the issue Roberto.
Worse if the dust Shields are wrong or if the brakes is a mishaps mash of different parts

NO. This is not for our late 50s cars. You need to have the right parts in order for the brakes to function correctly. No short cuts. No jury-rigging.

This message board is full of posts by people that have little knowledge of late 50s brakes, yet when offered advice by people that have learned thru experience how to dial in the brakes to work well, they ignore that advice because they are looking for a quick fix or because a friend or clueless mechanic told them otherwise. Then after they spent hundreds or thousands of dollars only to end up back where they started, they will once again seek advice from the message board.

I have the very very best brake shoes for your Plymouth -- which are N.O.S. -- Your car uses the
11" x 2" Front & Rear.....
If you resolve the issue you are having -- I can send those brake shoes
to Australia -- with NO CORES required -- so you don't have to spend a lot of money sending back the
Cores..... I will let you have them outright, if you would like....

Looks like we have found some issues, The people who did the rear brakes put the return springs not where they suppose to be
which is on the Spring link, 1st photo is Steve's 58 Plymouth rear drum, which is in the correct spot I'm going to use my front
brake shoes to replace the rear ones there virtually brand new with plenty of meat left, I have AAJ front Disc Brakes I'll get the
correct support plates from Ron, hopefully this should sort it out.

Not to mention that the axle has had the Bejasus beaten out of it! How did the brakes go Rob?

Steve took the car for a run it was heaps better with the springs in the correct spot, once I replace
the support plates with the correct 1958 plates and the shoes I think Im going to be good to go!

My rear brakes would get really bad about 20 mins into driving with heavy traffic, I go to a stop and
when I'd take off the car wouldn't even move, had to put it in Reverse, then quickly back into Drive
to get the car moving forward, Plenty of Brake Locking up, very hairy in bumper to bumper traffic

I was wondering about the return springs. In defense of whoever put them in the wrong spot, it is actually the correct spot for the front brake return springs. I don't know why the difference but they are different front to back.

In the links below, there's a lot of information - also about the rear return springs mounting to the loop for to reduce noice (59)

With the old retainer type, the springs could tend to pull the shoe outwards too much, with the new retainer, the springs can be mounted in the loop of the spring.

Note also the different type of return springs.

Bloody good news Rob. I don't know Plymouth (I know a bit about 60 Chry), but also keep a keen eye on the return springs, there are different rated springs. Steve.

It looks as if you should have "Triple Platform" brakes but your shoes are earlier. The coil retaining springs instead of "butterfly" retainer clips lead me to this conclusion. If that's the case, the shoes are being pushed into the backing plate and out of center line with the drums and support plate. You'll need to look at your backing plate (dust shield) to see if it has six raised bosses (platforms) there per shoe, towards the edge of the plate ender the shoes. The shoes should have three "contact loops" which lightly rest on the platforms.
