I will sell you all of my ABS parts

I am in the midst of installing the system referenced in this thread.  I suspect there are many systems available now.,

 

Hi Erik, thanks, i'm looking forward.

There are not that many systems available... As I see it there are 2 kinds of people: people with a large garage who keep all their old parts (yes,me 😉 ) and normal people, who throw away broken things :-). Neither of them have a system available... 😄

Update on the next batch of brake kits -

I’ve made some design alterations to improve the bracketry, and to simplify the installation process. With less parts required, I’ve also been able to reduce the price. I reckon the first kit will be available in perhaps four weeks time. Those who have already expressed an interest, I have you on the list, and will contact you in due course.

I found this, it's not cheap but they say it was reconditioned

When I bought the esprit in 2009, my master pump was leaking oil. The car braked quite well, but the pedal was a bit hard. The abs group, (near the headlight) had been bought new by the old owner, so I I bought the latest new delco moraine powermaster III from the Lotus factory.
Now it still works well and I hope it still works for a long time, the pump turns on every three or four brakes for a few seconds, and the ABS works well. I change the oil often and I only use good quality dot4.
I noticed that often many people put too much oil, this spoils the pump and the car does not brake well.
I'm sorry Karl, I kept the old power master complete with tank and abs sensors, but honestly I would like to keep it, I always have the hope of being able to repair it.

Hi RS Blu,

I saw a simular add some time ago, and decided nearly to buy, but did not. Luckely because they are different, the pushrod is different. ( I saw that also in the operation manual I bough last.) But the owners of Pontiac's, Cadillac's .... have the same problems as we, so if I run into a cheap (also broken) one, i'm willing to buy, just to have a closer look.( I presume they are cheaper than the Lotus version...).

It is good to hear that your master is ca 10 years old. I believe, but it is hard to track, that the good working Delco Moraine's are the ones which were replaced... I think non of them reach the age of 20.

My advice: replace the brake fluid as indicated by the manufacterer (3-4 years will do), and especially take care the system is properly bleeded, so no air is in the master. You can do a lot yourself,  simply by depressurizing the system, and to flush the abs recirculation valves. When you depressurize, have a look into the reservoir: the amount of air is an indication how bad it is 🙂 let us know with a picture 🙂

 

To all who are going for a deletion of the Delco Moraine : i'm still interested to buy one!

I don't remember very well, but when I replaced mine I had to modify the pushrod, the cylindrical part where the pushrod is inserted in the master was longer and largest on the new unit so I had to remove an adapter that was on the pushrod.io I had to use a hacksaw, but I don't remember exactly what I took off.

This is my old unit , you can see the small cylinder

 

When I depressurize the brake , also in my rear tank the oil turns brown, but it did so even when the master was new.

 

my new unit with longer cilinder

here you can see the longer cylinder, obviously the pushrod must be shorter.
Now I think my new unit was from a pontiac ...

ciao Roberto

I collected the revised fabrications this morning, those of you who already expressed an interest I will be in touch with details soon.

Anyone else interested in ditching their Delco Moraine rubbish and fitting a brake kit please message me at espritservobrake01@yahoo.com

[Karl lambrechts]

And if you are interested to sell your broken Delco Moraine?, please message me. I still want to pay a fair amount , but let us be realistic, it is broken (master and/or pump)...  🙂. 

 

[Chillidoggy]

I now have 6 conversion kits left from the batch. Anyone else interested in ditching their Delco Moraine rubbish and fitting a brake kit please message me at espritservobrake01@yahoo.com

[Erikl]

I have been living with my conversion for a few weeks now.

Maybe the most telling observation I can make is:

I dont even think about the brakes any more.  They perform exactly as you would expect.  Pre conversion I was always thinking about how they would react when I pushed the pedal and what adjustments would I need to make.

Now the brakes are the same every time, well balanced and without drama.

I have made some additional observations and talked about the installation over on Lotus Talk if you care to read more.

Also happy to answer specific questions if you  want to reach out.  

[Chillidoggy]

I now have 4 conversion kits left from the batch. Anyone else interested in ditching their Delco Moraine rubbish and fitting a brake kit please message me at espritservobrake01@yahoo.com

[Chillidoggy]

And a discount is now available for TLF Full Forum Members.

[Giniw]

Are they gold plated for the gold ffm? :o

Powder-coated in Unobtanium, and includes two free tickets to the 2018 Lotus Festival.

[Giniw]

... with a nice used windscreen sticker?!

[Chillidoggy]

I now have only two brake kits left for allocation, if you want one, then please message me at espritservobrake01@yahoo.com

[Sparky]

And another one bites the dust...

[Giniw]

Was the original system totally out of order?

I am still not decided to swap (partly for potential legal reasons here and partly because I don't have had time to think about it as I am working on the M100 anyway) so might be interested to have parts the day I finally decide to have a serious look at mine ...

At least, please just don't bin the parts!

[Sparky]

The DM system was functionally good - one of the better ones I've driven - but throwing ABS FAIL regularly and inspiring no confidence.  The owner will be keeping the entire system, should any future owner decide to revert.

[ramjet]

And yet mine cause me no grief at all. 

Ah. I could possibly be a numpty. 

[Chris Onelevenr]

Can't wait to get @Sparky to do mine next month. Sounds like my ABS is in a similar state to the one just done i.e. system works but throws ABS light. Most importantly for me is that the brakes feel absolutely appalling and totally fail to inspire any confidence at all.

I will keep all the parts just in case a future owner wants them.

Have you driven one with the conversion....its quite a revelation...

[Sparky]

Sorted and ready for Jim to pick up on Sunday.  @Chillidoggy himself delivered this kit and helped me fit it, and he's a stickler for a precision installation!  The final result is very tidy, and the S4 brakes beautifully.

That is very tidy - the owner is in for a treat.

I like how you used a fitting between the old brake lines and the new coming from the Prop valve.  That is difficult work in there and that would make it easier with no compromise in performance.

[Sparky]

Thanks!  It's quite rewarding when you manage to make pipes nice and tidy.  Follow Ian's instructions to the letter and you're rewarded with something effective, reliable and quite elegant.

What's the gauge for?
