Has anyone done one of these? How hard and what can I expect in the way of cost? I believe in keeping original as much as possible but "Safety fast"!! --k

kayarbro,

Yes, this can be done. We have done it in the shop for some customers, however, it is a lot more work than you might wish on yourself, involving a different master cylinder and linkage, MGB front suspension and brakes, MGA wheels if you have steel wheels, and a modified MGB rear axle and housing, modified to fit the TD. This is the only combination that will give you good disc brakes and the original look. In fact, once you put the TD hub caps on the MGA wheels nobody can tell at all, unless they know their T cars and lay down under the front end. If you have a taste for this, repost and when I finish the 12 page article I'm writing on it, I'll make sure you are notified.

Motorbill,

 I would also like notification when you finish the article.

Cheers,

Where can I get a copy of info on changing MG_TD to disc brakes?

 

Thanks

Guys,

I know it's been a long time since I offered help with this. Life has lately become quite complicated for me, and the shop has eaten any time left over. I need to locate my original rough draft of the article I wrote on this subject and edit it. I'm hoping to find time for that soon. Other subscribers may have noticed that I haven't been quite as active in general lately. It's not because I don't wish to participate, or that I no longer care.

Life, as we all know quite well, takes many unexpected twists and turns, and mine has been twisting and turning quite a bit of late. While I enjoy these characteristics in a road, they can be tough in other contexts. I'll get back on the straightaway soon though, I'm sure. Cheers.

Bill W.

Hi -- my first time here.  Any progress on the writeup on converting a TD to disc brakes?  I've got one completely torn down for rebuild & this would be the time to do it. Would sure like to get my hands on how the pros do it!!  I'd happily settle for the draft if the final isn't yet available.

Any New info on Disc Brake conversion for TD

OK Guys,

I'll be back in the shop the first week of October. I'm on the road until then. I promise that when I get back I will get to work on this and convert the countless chicken scratchings and note into useful information!

Hi guys,

Ive done the job on a YB [ and as we all know, the TD was a weekend redesign on a YA chassis?! ]  So I think things should be the same for a TD conversion.

As Bill says its a significant job,  complete MGB front hub assemblies plus disc, caliper etc will be required. I modified the arms of my existing front shock absorbers [ no big job two spacer discs tack welded onto arms] It may be possible to use MGB shockers I will check the hole spacing . They are of course a lot cheaper than TD!

I stayed with the Existing Master cylinder, a new one that Id purchased before thinking about moving to LH drive and disc brakes. If you do this you will need a seperate additional brake fluid reservoir,[ no big deal], disc calipers need more fluid to drive them  than the old slaves and foot movement!. I also took the opportunity to put in a remote vac servo system.

Shorter track rods will be needed, I think I used  ones off a Midget , You could extend the thread on your  existing rods with a suitable die.

I should make two extra comments, I have not driven the car yet and I have a slight niggle about caster angle  and the car was undergoing a complete rebuild at the time, substantial mods like this are a darn sight easier during a rebuild!!

Disc wheels, as Bill said MGA, 4-stud 15 inch, make sure they are the later deep dish ones otherwise they will foul the calipers. I stuck with the existing back axle and found a four stud  drum that would fit. With the TD, a move to wire wheels might be indicated?? conversion kit for the rear wheels?

To end up , its definitely on to do a disc conversion, good winter project!! Collect all the bits, reconditioned and shiny, and wait until Bill gets the detailed assembly process together .

Cheers steve

I have not done it myself, but I have a good friend that changed a disc-wheeled TF 1250 to WW by taking the front hubs & spindles and the entire rear axle from an MGA 1500 and installing them on his TF.  I don't think it was a really complicated job, but it might be had to find a disc brake MGA set-up as many folks with 1500s have changed to disc brakes by going this route.  My bet is that it is much easier to use an MGA front end than an MGB one.

I said I would check hole spacing etc for MGB shockers vs YB/TD. The hole spacing is exactly the same!! ------------The white-hot speed of new car design in 60/70s!! I suppose if youve got a good suspension/steering design already [Issigonis?] why be in a rush to change!

Maybe things did change later on in the life of the MGB, apart from management and pollution laws that is, which changed the shocker design but the ones I have would definitely fit the YB [Ttype?]. The arms appear to be right length, spacing between arms is bigger hence my mod to the YB shocker. The MGB arms also look more rugged. I  now think I am going to replace my YB shocks with upgraded MGB ones now I have looked at both on the bench.

Another thing does occur to me, when everything is done, because the TD is so much ligher, it may be necessary to do some pressure balancing between front and rear brakes again I think that this would not be too difficult to do.

Overall disc brakes is a do-able mod but requires wing/fenders off at the very least, and as I say that a mental picture pops up, will there be sufficient clearance under the wing to allow for MGB shocker, the top of MGB shock is about an inch higher than the TD one.

Hope this is an encouragement 1

Cheers steve
