Rear brake disc conversion

[Sprint36]

You're inviting me round on Sunday to check out your new motor did you say? Want me to bring some hubs with me?

Took your advice p p collins and went for the escort front solid discs, glad I did at £6 each compared to £40 for cosworth discs, pictures show new caliper bracket too.

Darren,

Looking good, what are you doing for a handbrake?

David hopefully its going to be an adapted dolomite hybrid cable, failing that sierra modified cable.

Looking good.

When you've got the complete solution together any chance you could weigh the new parts and the equivent set of oe parts they replace? Be interesting to see if there is an improvement in unsprung mass. We can all benefit from that even if we've not got the horses to need the increased braking.

Why are the studs so damm long?.

[eightiesflamer]

Thanks Phil.
You are correct the studs are mega long, not to sure why, will machine em down if I need to.

By the way I am happy to share the information regarding the conversion if anyone is interested, its not difficult however you do need to be a little handy and dont mind doing some running around.

The rally ford escorts had long studs dont know why ??

[Nick C]

long studs make it easier (and therefore quicker) to line the wheels up when you refit them...

Seriously useful when it's pitch black and you're in a hurry to not lose time on the next rally section!

Looks very similiar to the kit I do but I use Maestro discs as these fit the original pcd therefore the original studs etc can be used but you need to remove the tin plate from the half shaft.

There were a few in the early nineties who used a XR3 set up, described as 'simple' it was in one of the DSR News of the time but it looks as if you are past the research stage

Having messed about with rear drums, I too was ready to enjoy some rear disc action!! I wanted to keep the SPRINT alloys as I think on my road car, they are the classy option. Having read this thread in detail, I have hopefully come up with another cheap-ish solution.

I started by looking for a deep disc that would fit over the SPRINT hub but had a diameter and offset deep enough to clear the original wheel. After using the excellent Brembo website:

I found the EARLY Ford Orion 1.3 discs would fit nicely. £20 later I had a pair which were shipped straight to my local machine shop:

to have the Triumph PCD holes drilled. The centre hole and face had to be opened up and faced to match the dimensions of the original drum. £45 was quite reasonable I think!

Next came the search for suitable calipers. The Ford ones are great but unfortunately the shape of the cassting is huge and fouls the wheel beautifully

When admiring the Green Dolomite in Albert Looms scrapyard http://www.albertlooms.com/ , Derby I found a late 90's Rover 820 sporting a pair of Lockheed rear calipers which look perfect. The car was on it's side so removal was a doddle. They charged me £20 for the pair including the very substantial handbrake cables which are a definate improvement over the original.

Having removed the axle brake back plates, it came to a trial fit up in the sunshine. The good news is they do and the required mounting bracket could be designed fairly easily. I am now awaiting a quote for the manufacture of 2 laser cut 10mm brackets. The original handbrake brakets can be cut off the axle tube which is nice! I think I'll use a Stauff hydraulic hose type clamp to secure the cables so watch this space.

Time for a brake, time for a KitKat!
