I've tested the greens and reds and the reds win hands down for this reason: The reds are designed to work at a MUCH higher temperature, but their cold performance is only fractionally worse than a green stuff (still better than standard pads from Mintex or Ferodo - the best of the standard). And here's the thing: if you drive enthusiastically, the DeLorean's solid discs heat up RAPIDLY. At this point, the reds really start to grab. A DeLorean will cheerfully out-brake a GTA (with its vented discs) when wearing reds and if you use DOT 5.1 fluid, there's much less chance of problems of boiling fluid.
Rob Williams has covered over 15000 miles with 260hp to play with using reds and 5.1 fluid and they're only halfway gone - and he has been working them HARD, including pulling up to a stop from 140mph with no visible effect.
I get trade from EBC so can beat Powerstop's price. Retail on reds excluding postage is:
Fronts £50.06
Rears £58.65
I do them for £99 for a full set incl postage.
As for how to know if the servo is going - basically the pedal feels "wooden" and you have really lean on them if braking hard. It's also likely to be causing a vac leak and causing the engine to run lean.
As for performing on a par with a modern car: remember the DeLorean can play a trump card that it shares with the Alpines (which use a 50/50 split and identical discs all round) and Porsche 911: it's engine is behind the rear axle. Where most cars do 90+% of their braking on the front wheels, the DeLorean can safely use the rears for a large proportion of its braking. With the original rear calipers (NB: NOT Jag ones), and a 50/50 m/c, the braking effort on the rear exceeds that at the front, but the larger diameter wheels, greater weight and larger "footprint", the fronts
still lock up first, and this is very important for safety.
A full set of calipers, stainless hoses and a 50/50 m/c is the most common job I ever do on DeLoreans. A new servo and redstuff pads really makes them keen. Of course at that point you realise from the squirrelly handling that you probably want polybushes esp at the fornt.... it never ends, but yes, the DeLorean can have very capable braking.
