After the gearbox the brakes are the biggest weakness in a great car
For a supercar, the Esprit has never been blessed with truely great brakes. Lotus used braking systems from other manufacturers for most Esprits, giving them the same brakes as a 'normal' road car. This has made the brakes one of the Esprit's biggest weakness. Lotus addressed this problem only recently with the 1999 Sport 350. This model was given disc and calipers made by AP Racing, giving the Sport 350 wonderful brakes. Lotus made the AP's standard in 2002 giving the last few Esprits what it had be crying out for for 26 years.
Lotus tried to sort the braking problem out in 1994 with the S4 Esprit. Late S4's were equipped with a Brembo set-up, which was a marked improvement over the previous Toyota system used for the previous decade. Although these were better, the Esprit was becoming faster. The S4s and V8's up to 2001 were all equipped with the same S4 set-up. Which from my experience wasn't particular good at inspiring confidence. This is mainly down to the ABS system, with gives the brake pedal a wooden feeling.
Previous to that, the Esprit was, as mention above, stuck with 'normal' car braking systems. Pre 84 Esprit even had solid disc all round and Pre 87 Esprit had inboard rear discs. All of which aren't up to the standard to the rest of the car. This page is designed to show you what is on offer to solve the Esprit's braking inadequacies.
Firstly you can change the standard pads to a higher quality pad. This is the first and cheapest upgrade. Secondly you can change the discs to something either larger or of better quality. You can also get drilled and/or grooved discs, which will help improve performance.
You can also change your brake hoses from plastic to braided, which will help increase pedal feel. The is a cheap and simple upgrade, which really should be done to all Esprits. A supercar with plastic brake hose isn't on!
After the above you can then look at changing the set-up, which includes pads, discs, hoses and calipers.
One option is to fit a later Lotus set-up, which will keep your Esprit semi-original and will improve the braking. This though is limited due to there only being a couple of systems worth having, the Brembo and AP. These will both be expensive from Lotus and you may have difficulty fitting, as wheel size and hub configuration come into play.
Secondly you can look into aftermarket systems. Both Brembo and AP have kits available to fit the Esprit, that are much cheaper than the one's they supplied to Lotus. There are also other companies that can supply kits, including Wilwood and HiSpec.
There are many options available to the Esprit owners, from a cheap pad change, to a full race set-up for those track days. But remember, it's no good putting huge 6-pot calipers on the front and leaving the rears as standard. That will give you more problems than answers, you'll need to keep your braking system balanced. Talk to the companies about what they think would be good for you.
LEW advise you to go for the best you can afford. After tyres, brakes are the most important safety device on your car.
Most Esprit parts suppliers can supply you upgraded pads, which should be the first thing you do if you're not upgrading your system in one go. There are many manufacturers to choose from including, EBC, Hawk, Porterfield, Ferodo & Mintex. I would check out Lotus Performance for Pads, as they have a good choice. South West Lotus Centre always have a good selection of parts if you're looking to upgrade to a later system, use your Club LEW discount to get started.
Next up you'll be wanting some braided hoses to replace your plastic ones. This will mean draining the hydraulic system, so you can get yourself some top quality brake fluid (see here for fluids). Most of our parts suppliers can sell you braided hoses for your system. Try PNM, SJ or PUK.
Once you've done the pads, fluid and hoses, there are some discs available before you get into changing the system with bigger calipers. See the companies below for more of what's available. There's plenty to choose from (especially if you have deep pockets).
PNM Engineering's HiSpec Brake Upgrade (1986-1993)
This is the kit fitted to LEW's Esprit and there is already a guide to fitting and a review on the modifications page. All I can say is we're happy with the upgrade and the price is good to. Read more about this kit here if you haven't already.

PNM are working on a 288mm rear disc for the oz wheels to go with the front hsp kit.

SJ do a few different kits, including the ones below. The best ones are the AP upgrade for the 87-93 Esprits (which includes new calipers) and also a upgrade for 93-01 Esprits with Brembo brakes.
