MG TD TF 1500 - Front brake backing plates

The brake backing plates which bolt to the steering knuckle in the front of the car are marked RH and LH. These plates are the mounting plates which hold the brake linings, the cylinders, etc.

There are two ways to mount each backing plate. And the holes for the brake cylinders are not symetrical to each other. There is also a small fifth hole in the backing plate, in the area of the four knuckle mounting holes which would indicate a forward or aft positioning of the backing plates.

Which way do they go, or as I suspicion, does it even matter? And how come I can't find these plates in the Moss Catalog?

As always, I really appreciate the help.

Dave,

I do not remember why and how I decided to install the back plates, but I can send to you some pictures of how they were mounted before dismantling and how they are presentely after restoring them.

Regards.

Jesus,

That would be wonderful. For some reason, I didn't think it was important at the time, or perhaps I thought they were interchangeable (I would have!)

I'll look forward to seeing your pictures. I have wide bandwidth access, so don't worry about the size of the files.

I thought my plates were stamped RH and LH.
Don Harmer

Don, they are. But...

You can orient them two ways (180 degree flip) and still have the cylinders mounted verticaly. I'm wondering if it matters. Thanks for considering my question.

warmly,

The rule is that the front wheel cylinder must actuate by pushing downward. Does that help?
Bud Krueger

sorta Bud.

And that is how you get two LEADING shoes... but what I'm wondering is once you have the brake plate ready to go, everything mounted on it, and the front wheel cylinder is pushing down, flipping the plate 180 degrees also yields a downward front cylinder, but does the slight asymetrical mounting of the cylinder become altered? In other words, I know left from right on the braking back plates, and I know the forward shoe pushes down, but the holes for the cylinder are not stamped on the horizontal axis, and I wonder if it matters.

Perhaps I'm over thinking this. Not the first time...

Dave, any chance of an image that I could post for folks to look at?

The Service Parts List(AKD 834)lists them as:
Backplate assembly- R/H 27H7281
Backplate assembly- L/H 27H7282

They're listed the same way in the Abingdon Spares catalog onpage 33, items 1 & 2.

The illustrations don't give any clues. Sorry
Bud Krueger

In all the ones I've taken apart, the small hole between the mounting bolt holes faces forward. Would it make any difference mounted 180 degree off? It shuldn't, the cylinders will still have the proper orientaion.
Ron Boisvert

Ron, that's exactly the information I was looking for. Warm Thanks!

I'm please I read your thread because I had done exactly the same as you! With the comments I could carry on assembly. A handy lot of experts out there!

John, it is like having trusted friends over for a beer while you assemble your project. Only, a bit less fun.

Question... on the TF can I remove the backplate while the the hub is installed?

Was thinking of removing the back plates to paint them as part of the brake rebuild.

Thanks.
