Wasn't it Sir Herbert Austin who said "Good brakes make for bad driving habits".

Like the local Escalate drivers that fling there SUvs around like they are Formula 3 cars and treat the brake pedal like an on/off switch?

...BTW, I tried to rebuild the original Girlings and was totally in a VERY VERY Bad mood after trying to install the rubber dust boots in the calipers. I spent an honest 2 hours trying to get ONE boot on, and after I got it on, it simply rolled off...

There is (like so many things) a trick to putting that boot on that gets the job done in under 10 seconds. Too late for your brakes but now that you've found this forum you'll find out about other tasks that may appear worse than they need to be.

well now you have my curiotsity piqued......
what is the trick???????
special tools??
 
FWIW, I have a TR6 with stock brakes and a TR250 with the Toyota caliper/Morgan rear cylinder upgrade. While by no means is it a direct before/after comparison (when I got them both cars had dead hydraulics from sitting and 1 has 205 Yokohamas and the other has 205 Dunlops) the 250 has much, much better braking feel. It's completely subjective I know but I never get that "whoops, I might have overcooked it a bit" feeling with the 250 that I sometimes get with the TR6. Perhaps the TR6 brakes could be improved with different pads or something as both use stock pads. I don't think I'll bother to change the TR6 to the same setup but if I needed to pitch the stock calipers/wheel cylinders I might consider it. If I do get another car with dead hydraulics I'd probably go the Toyota/Morgan route again.

Somewhere in the archives are old posts describing this. In brief what I do is have the boot in place in the inside groove in the caliper, position the piston atop the boot and (with the opposite caliper opening blocked) introduce modest compressed air into the caliper. The air inflates the boot and it really wants to go up and around the piston. I use a little hook of rounded 12ga copper wire to help it pop on. At that point the piston can be pressed home and the boot lip seated in the groove in the piston.

Everything is slathered in brake fluid to ease it along. The first one may take a couple of tries but by #4 it really is a 10 second task.

Easier with a helper -- my wife 'mans' the air gun and knows just how much pressure it takes to make it happen.

Assuming that the two systems are relatively equal performance and safety-wise I would have to say that the swap could still be a justifiable one simply due to the greater availability of Toyota replacement parts now and in the future.
It may be pure supposition on my part but I would have to believe that It will be a lot easier to find Toyota parts than stock TR parts 20-30 years from now.

I mean...you know...when we all finally have flying, anti-gravity cars like we were told we would back in the 60's
 
What did you have to mod with the hoses? I might do this simply because I need calipers and Toyotas are cheaper.

I took a piece of brakeline and added the triumph end on one side, and the toyota style end on the other.
I have a flaring kit to do this with.
It is tricky to get the fancy bends they mention in the conversion. I find it easier to simply remove the line first, then unbolt the calipers.
 
Just bring the hoses to a local hose fabrication shop, 30 minutes and they'll have you all set.

Bring the hold hoses and caliper with you to make sure they get it right!
 
A few years ago I got prebent stainless adapters from https://www.trparts.com/

The site's no longer active. Does anyone remember who this was?

BTW, I wouldn't do the Toyota front calipers without using the Morgan rear wheel cylinders (exactly the same but with a larger bore - available cheap from VB). They seem to be well balanced with the Toyota calipers.
