Discussion
I ran these four pot calipers for some time, as you can see compared to the standard caliper, they are four piston and also give around 30% more pad area.
They bolt straight onto the standard bracket and onto the standard size non vented disc.
As I recall the only difference is they are a 10mm metric thread for the brake line instead of UNF.
I think they are/were used on Transit vans, the Lockheed part number cast on them is 3247-637C.
I dont have a clue however as to how cheap they are in terms of your Mega cheap requirement, or even if they are still readily available, I got them direct from Brakes International at Rochdale, they do have a web site with contact details.
They worked very well.

Yes the four pots in the picture are an improvement and are suitable for both road and track use, but I would also say the standard calipers in good condition and, as already suggested, with an upgrade in brake pad material, are perfectly adequate to stop a standard M.
If I was buying new calipers anyway, I would go for the four pots.

1) Does changing the discs for drilled and slotted discs make much difference?
2) Does fitting vented discs (and spacing the calipers) help much?
Most of the four pot calipers from other cars are a lot heavier than the Triumph calipers.
I already have Adrians "superpads".
I don't want to increase my unsprung weight unecessarily and I was thinking of upgrading the discs. Vented discs are quite a bit heavier.
Has anyone tried different discs and would like to share their experience?
3) Does anyone have any feeling about "Alfin" type rear drums? Have you tried them and do they make any difference? It is only after a track day that I really get the urge to improve my brakes.

Boys and Girls, thanks for the input my thoughts are as follows:
OPTION 1 - Refurbish my existing calipers
Recon Calipers from Rimmer brothers = 2 x £80
Delivery £15
send back my old ones £15
TOTAL = £190.00
OPTION 2 - Hi Spec
I have spoken to High Spec in Dartford today to see if they do a straight 4 pot replacement, as looking in their 2005 brochure they are listing Hi Spec alloy 4 pot princess calipers for £120 each !! They are going to phone back tommorrow with details of what if anything they can do as a straight bolt on option. If they could do new alloy 4 pots for £120 + vat each which i could collect, i may be well chuffed.

My 5000M has Wilwood four pots with vented discs and 15" wheel upgrade to fit them in.
I originally ran Red Stuff with them but found I never got them warm let alone hot. I'm now on Green Stuff and there still difficult for me to warm up in time ...
I guess this brings three things into the equation - what are you using the car for, what is your driving style and is anything else modified ?
I'm a very novice sprinter - the car is a little under developed in other areas especially suspension/diff. I drive the car quite hard but not hard enough (ie room for improvement on the driver.)
With hindsight I should have gone for stiffer springs and better anti roll bars before the brake upgrade so that I felt comfortable driving the car fast and knowing what happens when I brake really hard. (ie I should have been driving the original brakes to their limit).
Dive and roll are bigger problems than stopping power in my opinion
One last comment I guess is if you're going to use the car on the road regularly I'd definately make sure you can get the brakes up to temperature quickly !!
Not sure if this is useful ??
