Brake pads for 90 Esprit SE?


Recommended Posts

Hello all,

What brake pads are recommended for a 1990 Lotus Esprit SE?  I'm in the US, I never track or race the car, so I don't need racing pads.

I'm asking this question because, when I searched the forums, the most recent infomation posted was from about 10 years ago, so I'm looking for more recent advice.

Has anyone tried the Centric 10505270 Posi-Quiet Ceramic and how are they?  (They also make a Posi-Quiet Metallic)  Is ceramic or metallic better?  The Centric pads keep showing up as the only choice on parts sites such as rockauto.com, carparts.com, buybrakes.com, partsgeek.com.

All that JAEparts.com and rdent.com sell are the EBC Yellow ones, and I don't race, so I don't need those.

Some have said Porterfield are good.  Is that still the case?  Porterfield R4-S cost more than 3x as much as the Centric pads -- is it worth that much extra?

Thanks in advance,
Dan

The choice of pads for a Toyota based system depends on your driving. The TMC system never provided an adequate amount of braking for the Esprit's performance...witness the expensive, high-performance Ferodo pads that Lotus fitted from the factory.

One downside to performance pads is high levels of brake dust. :X When I was tracking my Esprit and had performance pads fitted, I needed to clean the front wheels after every drive.  That got old after a few years.

 

I am currently running ceramic front pads for street driving. These DO fade a bit during the most spirited drives, but under normal running conditions are fine. (EBC Yellows in the rear)  I'm sure the Centric ceramic pads would perform in a similar manner.

 

You can search for pads from various makers by looking for "1983 Toyota Celica Supra 2.8L" fitments, but DON'T get the cheap stuff...I still have vivid memories of a friend's Esprit brakes igniting at BlackHawk Raceway at a Lotus Owners Gathering...:cry:

RA and Tire Rack both list Centric 10502450 ceramics for the 2.8L Celica.

I have the Porterfiend R4-S on my race calipers and really don't like those pads at all...  They do not work in the wet at all.

I would stick with an organic over a ceramic pad.  If you aren't driving fast, then a normal works fine.  If you are going to be driving spiritedly, then a better pad is a good idea.

Travis,

An ORGANIC pad is the cheapest type of material you can buy for any car, isn't it?  A semi-metallic is the MINIMUM you should use on an Esprit, I would think.

 

Granted, semi-metallic pads have better reported stopping power than Ceramics, but my experience is: it is worth the trade-off.  I've only had fade once since installing them several years ago. And I haven't found them wanting regards stopping power.

 

(It helps to keep muttering to yourself, "BRAKES ARE FOR SISSIES"...):sofa:

If he's not driving fast, then organic will give the best feel and works in the wet, and doesn't wear the rotors.

If he's driving fast, then a semi-metallic would be better, but have less feel, may not work as well cold/wet, and will wear the rotors faster.

A ceramic is really only for long life of the pads... With generally worse feel, lower initial bite, worse friction in rain, worse rotor life (SE rear rotors are hard to get and expensive).

 

If he's driving track, then something else entirely would be needed.

 I've heard good things of Mintex m1144

That is the compound I was using when I tracked my Esprit. They were dusty!!!!!  but worked well.

I've got them on my Elise and I'm very impressed with them.

Thanks for the replies everybody.  I decided to go with the Centric 10505270 Posi-Quiet Ceramic for the front, and so far they seem absolutely fine.

For the rear pads I bought the Centric 10411630 Posi-Quiet Semi-Metallic (they didn't have ceramic rear pads), but I haven't installed them yet because I'm not sure they are correct.  They fit, but they have a protruding nub on the back (see picture).. The rear pads currently on my car don't have that protrusion. 

Since the rear calipers require you to rotate/screw the piston to get them to compress, doesn't that mean as they self adjust they will rotate/screw?  

The only way to get the pads to fit is to put that nub in the slot on the caliper piston. If I do that I don't think the caliper piston will be able to self adjust, because it won't be able to rotate/screw out.  Am I incorrect in my logic?

Dan, When I had standard brakes on my 1990 SE, I installed new pads all around, and they are/were Black street pads from EBC, that actually Work okay (-ish, but that is simply bad brake design, not pads). Green stuff etc. are crap, so save the time, effort and Money. Just get pads from the UK id not available in the US. I seem to remember that even Sparky commented my standard brakes as working well with those pads, after a belt change.

They are not loosing pad material as in seperating from metal backings, they don't ignite and they brake just fine for street driving. Not fast back road driving, as the brakes are dangerously underpowered from factory! I mean that. And the ABS didn't exactly make it any better. In my humble view, Lotus should have recalled all Esprits of that tmc (whatever) system, and swapped it over for free to AP Racing Sport350 system both front and rear, years ago. I am sure some Esprits and possibly peoples Health could have been saved, that way.

Kind regards,

Jacques

What Jacques said is spot on,   I used the green stuff pads on standard front callipers and grooved discs and found them to be complete shxxe ,  Best of sticking with standard pads or looking at a complete upgrade with new discs and callipers from one of the specialists if you are are after better stopping power.

I certainly agree with Dan, but I'll add that of course the standard calipers will have to be fully functioning. Not drag, or being stuck in some sort of way. Some people say taht it's only important eith front calipers (brakes), as they do most of the Work, but on exactly the Esprit, I have found the rear brakes to be very efficient in slowing Down the car, because of the engine position and weight distribution. And take a look at the small hoses from the brake master and it's vacuum booster. There is a small White plastic one way valve, that should Work as well, to prevent the pedal from feeling too stubborn ;)

The standard brakes can be made to Work relatively okay. But if you want to even think about using the Esprits power, get better brakes all around. Plenty of offerings on the market, incl. discs, calipers and pads in all sort of combinations. As the original poster said that he was not looking for that (no track or super fast driving), I would still advocate for better brakes, as they are dangerous and the Esprit is wayyyy too fast for the standard setup.

And please drop the al original idea, and go get some braided hoses, or at least new rubber hoses ;) (no offence intended).

Kind regards,

Jacques

Atwell: that may be ;) But if you do as I do, and drive on small narrow backroads and enjoy turns and hilltops, then you'll also appreciate good brakes, when suddenly having a female teenager on a horse jumping right in front of you. Or 35 fat old men in multicoloured spandex, simulating Tour de France (read: taking up all of the road) ;)

Here's one of many I got two days ago, plus some twisted bones (in a mtb crash in the forrest):

Kind regards,

Jacques

Sparky said the rear calipers DON'T rotate as they self-adjust. I don't understand, because I had to rotate the calipers to get them to compress, so logically wouldn't they rotate back as they extend?

My big questions:

1) Is that nub supposed to be there?

The only way to install the rear pad pictured is to put the nub in the slot on the face of the caliper piston, so

2) Will the caliper and brakes be damaged as the caliper extends because of the interference between the nub and the caliper?

Do you mean EBC Ultimax? I've fitted these all round on my SE and I daresay they are shit. I think what came off was the original factory pad (Ferodo?) which bit a lot better. I believe I'll be changing them. Ironically EBC recommend Green Stuff as the next step up, and ironically every single poster on this forum has said they should be avoided....

You may be right Vanya, but I've driven with both, and the Black ebc streetpads were surely better than the ebc greenstuff. Once, after a fraction of spirited driving, I had smoke coming out of all four corners with the ebc greenstuff. And no, they didn't slow Down the car very much... It was like holding a child size umbrella out the window, while I screamed: ne me quitte pas...

Dangerous stuff. I found the Black pads better for street driving. But still far from great, I may add.

But surely a pad like Ferrodo DS2500 is a totally different League. Or the DS3000 that I am using on my Corrado G60. I just did not find them available for the Esprit's standard brakes, so decided I needed bigger brakes with higher capacity and bite, before crashing.

Kind regards,

Jacques

Dan, 

       I think you have to rotate the rear calliper pistons back as they are pushed out by fluid pressure for the footbrake and mechanical for the handbrake,  I presume that is hy you always have to rotate rear callipers pistons back as the automatic integral handbrake mechanism needs winding back.  That is what i have always thought any how :)
