Atlanta Esprit Gang - ABS Delete Party

Evening folks,

I ordered the ABS delete kit from the UK.

Details:

https://www.thelotusforums.com/forum...-abs-deletion/


I really would have liked to spend this money on other improvements but I think this will really increase my enjoyment of the car on fast back roads and support future brake upgrades I am planning for the occasional track days.

So - kit should be here in a few days and I thought I would offer up if anybody wanted to help or watch all or part of the install I will open the garage. Of course we will be going for drives after words so we can experience the change....you have to promise to say its night and day better because it is a lot of money for me

I will probably start the process on a saturday and maybe finish on Sunday. Might be more interesting to come out on Sunday so you can have a drive.

If you are interested post up!

I will be sure to post when I nail down a schedule.

I need to go through the instructions and make sure I have all of the necessary tools and supplies.

If it looks like a quick job I might try to ply @DaveS4s to let me use his lift. I think it will take 6 - 10 hours so will do the job here.

I live in Conyers GA and I will supply coffee and soft drinks

I have the V8 master cyl with brembo brakes driven by an electric pump with buffer tank installed. The first iteration used a common volvo vacuum switch which was maintaining about -8psi which was too low, but the 2nd update has a different switch commonly used in EV's which has the required vacuum for the v8 master.

The front two brakes are teed from the front piston on the master.

I've been researching (and now have all the parts) to insert the Kelsey Hayes EBS pump from the same V8 system. I'll need to add a 2nd line to the rear to make it a 4 channel system. So far the data I have says the wheel sensors are the same -- and from the schematics it looks like it's a matter of installing the new plug for the K/H system on the existing wiring.

I'm waiting until I finish the turbo upgrade project before I tackle the 2nd phase of the brake upgrade.

I'll grab some pics to show the configuration of the current system.

Yeah I looked at several different ways to do this, in the end I liked the "complete" kit approach with Lotus parts where applicable. I thought that would have the smallest hit on resale. That is cool that you might have 4 channel ABS. I cant wait to see if this set up gives the feel I want.

The kit has a proportioning valve for the rear brakes because the rears are a little to strong with this MC. Its going to be great to be able to tune the rears. Years ago I had a race car with adjustable rear bias, once you set it so the rears lock up just after the fronts its really a great feel. Not as safe as OEM but faster around the track :-) ALso takes some of the load off the fronts I figure

Love to see pics of your set up.

Yes

I have that on my car now.

I felt it was an improvement but I was still not getting the performance from the rears that I wanted.

I will send you the resistors when my new system is installed and you can try them if you like.

Interesting - was the V8 vacuum servo a bolt on?

OK

Finally got around to Installing the system. I putzed around for a few weeks, then had an issue with a leak (self imposed) on the vacuum manifold. Had to wait for a new one to be shipped from the UK.

By far the worst part is flaring the brake lines, there is two different types of flares, I learned a lot and screwed some flares up So I had a shop do a couple of the flares for me - only $50.

Now that I know what I am doing I could install much more quickly.

Took it for a first drive today feels great! Still have some tuning to do.

Its really great because you can adjust the rear brake pressure and the assist pressure for a firmer pedal.

I will get a couple pics of the install tomorrow.

The best thing is now I feel like I can move forward with some larger discs and calipers for great feel and no fading on the track.

I have thought about offering to install or help install the kits

I think I made about every mistake Possible. It was odd, I consider myself an advanced DIY wrench but I had some preconceptions about how vacuum brake systems work that were wrong and some things that I never would of thought would affect the way the switch and sensors work did affect them. At one point during the process I could not get the system to hold vacuum and I went through a series of checks over a couple of days that lead me to think that almost each part in the system was faulty or leaking. Later I confirmed that none of the parts were faulty or leaking...arrgh.

Fortunately, Ian, the guy selling the kits is very patient, knowledgeable and helpful. Made it through!

I would love to fly to Denver and help install the kit...but by the time I charged a little for my time and the cost of the flight and (I eat a lot :-)) It would probably be cheaper to have a shop do it...and they have to warranty their work.

If I screw up I just shrug and apologize :-)

I think it could be installed over a two long days with a bit of pre work and pre planning, especially if two people were working together.

I ordered two short brake lines from INline Tube with the correct flares and fittings.

https://www.inlinetube.com/?gclid=Cj...EaAgPfEALw_wcB

The kit comes with brake line and fittings but the "bubble DIN flare" That you have to do on one end of the lines is not common in the cheapy flare kits we get here in the US and I did not want to buy an expensive flaring tool...then I crimped one of the lines I bought when bending it...arrgh. So I took the master cyl assembly to a shop that works on a lot of old british cars and he flared and bent up the lines for me - no problem.

Anyway now I know how and what to do and it would go MUCH smoother.

Cant wait to get some bigger rotors on there.

I will throw this out there - if some one wants help installing one of these kits.

Fly me in Friday
Let me sleep on the couch and feed me.
Give me $1000 - I figure that's $50 an hour.
I will fly out Monday night.

If I spill brake fluid on your fender its on you :-)

Also, you could reach out to Ian and see about looking over the instruction manual.

He currently has 7 kits built up and ready to go!

Erik - I'm very pleased to hear it's all done now and you can enjoy driving the car again. Please let me know how things progress in the future as you change calipers/discs/pads/.

After reading Erik's text, to anyone considering a conversion - I would not recommend a two day period for kit installation. When I do them myself, it takes me three days, and I know precisely what I'm doing. Add in the subsequent checking, testing and setting up, and five days should be allowed from start to finish if you haven't done the job before. These are brakes, and nothing should be rushed. Different people have different levels of technical expertise. I supply kits to some, and a couple of weeks later they tell me they've completed the job. Others send my inbox multiple queries but I provide as much support as is required. Being UK-based, it's a difficult task for me to pay anyone in the US a visit (unless you're in FLA late September/early October), but the online advice is always there.

If anyone is interested in a kit, then please e-mail me at [email protected].

"Ian, the guy selling the kits is very patient, knowledgeable and helpful." Thanks Erik, I confess there were times when I thought I was going to have to jump on a plane to GA with a bag of tools to sort it all out for you!

I think it's fair to say Erik had a bit of a challenge in front of him, and I'm pleased to see him finally make the finish line. A word of advice though - It takes me 3 days to do the conversion (and I know precisely what I'm doing), with maybe another day of setting up and testing. In my view two days is not long enough to make sure the system is fully functional, it cannot be rushed.

If anyone else is interested in ditching the Delco system and fitting a brake conversion, e-mail me at [email protected], I have kits available at the moment, for LHD or RHD.

Yep - most of my issues were because I was trying to test parts of the system when other parts were not in place. I did not think there was interaction between the different pieces but there was and I confused my self. I also had a few language barriers - Folks over there have different names for some fittings/tools/procedures and I assumed I knew the translation but I was wrong a couple of times.

Finally - I over tightened a fitting into an aluminum thread and ...it stripped/cracked....I should know better.

I was quick to shoot Ian an e-mail - it helped me to think and process, it probably drove him nuts....anyway - I got it figured out now and would be happy to assist in person or on the phone/e-mail.

Two days is not possible start to finish, I was thinking we would complete some of the steps before I arrived, possibly some of the disassembly would already be done - etc.

What's the matter Ian, did you forget your username & password here?

chilidoggy and ian29gte are the same guy, LOL. I'm sure a Mod could combine those for you!

Lovely work, gents. And it's a very cool looking system - the photos are impressive and may be added to my Lotus porn collection :-). You know, this whole dialogue is just another example of why I love being associated with these cars and the community of folks who own and drive them. I mean, really, maybe other Brit cars have a similar sort of camaraderie and willingness to help but this group is something special.

Curious.My brakes feel like s brick when braking and take a long distance to stop. Does this mean I should delete my ABS system or get larger brake pads?
