Caterham brake upgrade

Following the installation of my Zetec engine (other thread running) I was hoping to get some advice from you knowledgeable lot.

I feel I should be upgrading the brakes to handle the significant increase in power / speed. Current set-up is standard S3 (car is circa 89).

I have had a look round and there appears to be the following options (in ascending order of expense):

Replace pads with Mintex 1144's
Replace master cylinder (along with above)
Hi-Spec (sp?) big brake kit
Wilwood 4 pot callipers
AP Racing callipers

I should mention that I am running 13 inch Revolution wheels (which I don’t want to change) on narrow track geometry (which I don’t want to change).

Does anyone have any thoughts on the options above (or another that I hadn’t considered) or any real world experience of the options?

I have had a read through blat chat and there seems to be advocates and opponents of all of the above.

Thanks in advance.

ETA: I did try the PH search but it didnt seem to work / return any results.

I'm running a 2.0 Zetec and quite happy with the standard stoppers. They're good for anchoring a 790 kg Triumph Spitfire so should be good for a 500 kg Caterham. Not sure I really need to fit my AP Racing calipers. Just adds more unsprung mass.

AP calipers are lighter than STD calipers

The AP "race" master cylinder has a larger bore than the standard one, and gives a firmer pedal, requiring more pedal pressure for the same stopping power.

Standard M/C is 5/8" bore and the AP one is one is 13/16" bore, requiring something like 1.6 times the pedal pressure, but with 1.6 time less travel. However, the AP M/C also has less free travel before it starts to act than the standard M/C, so it feels like the AP M/C has even less travel.

It's possible to fit a belled washer under the standard M/C to reduce some of the initial movement, and reduce the difference between the standard and AP M/C's.

Whilst the AP calipers are lighter than the standard Triumph calipers, the big vented disks are much heavier than the standard Triumph ones.

Both Hi-Spec, and Wilwood make calipers that are significantly lighter than the AP calipers, and can be used with either standard disks or slightly larger but solid disks, giving an overall lighter weight package.

Interesting So as usual, what you gain in one area, you lose in another.
I didn't have much luck with Hispec when I was looking for calipers, a bit like dealing with Mike Barnby. Plus I hear they flex a bit being three piece design.
I found BDG very helpful http://www.bgdevelopments.co.uk/ they make some nice alloy disc bells for not a lot of money considering the quality.
They actualy do a lot of the machining for AP.

From memory I think my pedal always felt a little spongy with the standard m/c which is why I changed to the race m/c as I prefer a more solid pedal 'feel'.

Thanks chaps.

Any chance of part numbers Aeroscreens and Bert Bert (to avoid any confusion).

Must admit I am still a bit concerned about dissipating all that additional energy with standard (old) brakes. However will take the advice offered so far and start at the lower cost end of the "solutions".

Did either of you find problems with heel and toe after messing around with the MC or pedal ratios?

Here's the "high effort" (!) pedal

Costs £24.45!

Inflation on it's own would make that £34.62 today, ouch!

If the weight of the car doesn't go up it wont require more braking.
I bet you can lock the brakes now, so do you need more braking ?

Sure, on track you may want to avoid fade, but for the road I'm not sure spending money on upgrading the brakes will be necessary just because you have more power.
