Adding ABS to NAS Defender

Is it possible or has it this been done?
Can you add ABS to a NAS spec. Defender???
I am tired of the old pump-N-pray when the streets are slick and I need to stop.

All things are possible, you need ABS exciters on the CVs/rear axle, the ABS ECU, the ABS master cylinder and wheel sensors for all four wheels. Then you need a lots of patience.

I have a friend with a Disco1 who is looking to get rid of his ABS... maybe you two could swap the parts?

Get better tires... ABS is not needed and can make things worse, IME.

Could it even be done with the drum brakes in 110?

You would need abs sensors which would mean replacing both the salisbury and the front axle with something ABS compatible.

1997 D90s have the wheel sensors. You could probably add it to a 1997 D90 with a lot of work as opposed to the metric ton of work needed to fit it to a 1993-95.

They are rough road sensors...

Rover probably did it because they had a ton of axles and CV from the discos.

I thing because ODBII was required to be implemented in all cars sold in North America in 1996 that Rover could or had to put ABS sensors and other sensors on the 97 Defenders.

Hi Jon,
Try to apply the brakes with better technique, i.e. smoother. I won't get into a whole threshold brake talk here, but the initial push of the brake pedal must be smooth enough to transfer some weight to the front tires, then you can push harder because that weight transfer pushes the tires into the road surface more. If the front tires do lock up, don't pump the brakes (like my driver's ed teacher told us to do) and completely release the brakes and then jam them back on again over and over. All you need is a smooth release of a LITTLE brake pressure...just enough to get the tires rolling again, but not too much to transfer the weight off the tires. Little tiny adjustments to keep the tires rolling.

Easy to say, but tough to do sometimes in an emergency situation. That's all ABS does though. It detects lock up and releases a touch of pressure at about 17 times a second. Even if you have ABS, you should know how to do this.

Also, (and I'm really not trying to be preachy, this is just what I do) you should not be engaging your ABS that often where you should be "tired" of it. If you know the streets are slick, back off the car in front and anticipate more. Red90 is right too, better tires will definitely help. Tires are the most important piece of equipment on your rig, because they're the ONLY thing that's touching the road.

Hope that helps!

x2 to what Pete said with the additional comment that MT tires are terrible in rain. Get something with a lot of sipes and you will be able to stop fine.

i think the 97 models have a speed transducer that relays the speed to the speedometer perhaps it gathers some info from the wheel speed sensors. but nothing to do with the brakes.

just buy a 1999 or above with ABS from the UK and swap the vin #, easy.

I'm sure you could buy all the components for ABS starting with the axles, the ABS pump and sub systems, and the computer etc (perhaps as used or take-out), but I think it would definitely be more cost than its worth. I've only activated ABS once on a car and that was during a panic event at about 170kms/hr on the autobahn.
