Persevere with it, the car is already over braked on the rear, discs will only make it worse. As RedThree has shown, the original is fine if set up correctly, even if it is 1960’s ford Transit…

Excellent post indeed. Great Forum support

The rear Disc brake conversion doesn't make it worse! It improves the feel of the brakes and makes maintenance a doddle.

I cannot believe what I am reading in this post, is it a joke ?
It is blatantly obvious the wheel was put in incorrectly with the brake plate not secured in the slot.
How anyone could do that beggars belief !
There is no other way such damage could occur.
I suggest that you let professionals work on your Morgan to avoid causing yourself or others serious harm.
By the way the disc is a spot on conversion and benefits those of us who are serious users. Yesterday I did 15 Hill Ascents in my M3W at Prescott Hill Climb raising money for the BloodBikers. The Disc brake far outperformed the drum.

I take a different view.
Not everyone has the background that magically produces a good mechanic and I doubt if there are many good mechanics out there that haven't cocked up many times on the path to competence and crucially have learned from the experience. let he who is without sin cast the first stone and all that...
Jonathan has made a mistake, admitted it and is learning the hard way just how expensive it can be to make an error and not catch it before it matters.
I've never had brake fade in my M3W, can lock the brakes at any speed at will on any dry surface should I choose to so there isn't a great deal wrong with the brakes overall. While I don't circuit race my car, I suspect that would be the only case where brake fade in a correctly maintained M3W could be an issue. Certainly in the track days I've done I've had no problems. Last time I was at Caramulo I did about ten consecutive high speed untimed "parade" runs up the hill in quick succession on the Friday before the competition again without issue. Even on the quickest of my "it's not big and it's not clever" early morning laps of the TT circuit last week I had no issue despite some of the high speed slow downs required which is more than I can say of some of the road bikes I've ridden round there! Hence my thoughts that the disk conversion is unnecessary, however nice it may look. I also happen to like drum handbrakes once they are set up correctly they have a tendency for excellent engineering reasons to be very effective and rather better than most disk systems are.

Thank you Red Three. I would also like to add that it takes a big person to own up to such a fundamental error and ask for help on a public board. The last thing anyone deserves in such a position is ridicule and derision. I hope I never make such a post.

It’s about knowing and learning about our limitations and so, on a lighter note…
…a poem “Lord Finchley” by Hilaire Belloc

Lord Finchley tried to mend the electric light
Himself. It struck him dead: And serve him right!
It is the business of the wealthy man
To give employment to the artisan.

Well said, Callum, and great to meet you in person finally on the Isle of Man.

Good luck Johnathon in sorting out your rear brakes, every mistake is a valuable lesson learnt for anybody and anyone that takes on something new to them will not get it right first time every time.
No one on here that is hands on will be faultless I can guarantee that as it's not the way engineering works in my lifetime of being involved in it.

Well done admitting yours and reaching out publicly, this forum is the place for sharing mechanical encouragement/knowledge and friendship .

My apologies, I’d missed the fact that the question was regarding a three wheeler, not a four…
