    ABS Issue

    Hi All,

    '96 Disco 1, v8i.

    I was wondering if anyone would be able to advise on this issue that im experiencing.

    The issue is the ABS engages in at any time the brake pedal is pressed. This often happens for no apparent reason. I then need to let the brake pedal go, and re-apply the brake and then the ABS disengages. This even happens at very low speeds.

    When it engages, it sounds like the ABS 'mechansim' whining (like a motor sound).

    I was wondering if anyone would be able to advise on what to check for and where to check.

    My first thought is ABS controller. Any thoughts.

    TIA
    SHaun

    Hi Shaun
    I have posted replies to similar issues with ABS in the past and would offer the same advise to you.Get it checked out by someone with the ability to diagnose the problem and fix it properly.
    I too had an unusual and intermittent problem with the ABS and almost found out the hardest way that this system is far from fail-safe.One of the wheel sensors had an intermittent fault and would cause the ABS to operate when the pedal was pressed,end result next to no braking force.After almost going through a busy intersection at walking speed I took the car to a local Land Rover service center had the fault diagnosed ,sensor replaced and no further issues.
    I enjoy a tinker as much as the next bloke but its not worth risking your safety and others messing around trying to work out fault codes etc.
    Hope this helps
    (P.S cost about $250 to have repaired)

    simple cheap ABS fix

    HI,
    I had a similar problem with my ABS on my 96 Disco where 9 out of 10 times the brakes would let go more than they would grip I had a 3 step solution

    1. remove the ABS fuse from the fuse box this will disable your ABS and leave you with standard locking breaks unfortunately this will also leave you with a happy yellow light informing you of an ABS fault (nah dah)

    2. take apart your dash and remove the globe behind the ABS light

    3. put it all back together again

    tadah you now can pass road worthy and should have working brakes sadly though these will be normal brakes but hey as the old outback saying goes KEEP IT SIMPLE.

    I think there may be some more steps to this
    When you have the accident explaining to Insurance Companies and Authorities (hopefully not the Coroner)
    Be careful you might go for years but if Murphy visits it could be all bad

    just take it to a land rover garage and have it put on the test book...it will tell you whats wrong with the braking in terms of whether it is a sensor or the module etc....


    There is one thing you shouldn't mess with and that is brakes...

    Now I had real ABS issues on my car and it ended up being an intermittent wheel sensor as soon as it was changed never an issue again.

    I never had the whining like you though but I had moments when the brakes were inactive and simply didn't work and used to have to pull up the hand brake. This would happen at all different times mainly at slowish speed stuff and especially if bumping up a curb slightly in to a drive way while slowing on the brakes..
    Our Land Rover does not leak oil! it just marks its territory.......

    In my line of work, I curse people that perfrom this action, the vehicle is then deamed unroadworthy and uninsurable, the results of which have far reaching effects, give that some thought before you go messing with any vehicles safety systems. If it has a fault, fix it. If you can't afford to fix it, then get rid of the vehicle and buy a cheaper to maintain vehicle.
    The worse thing is that you may then sell the vehicle to someone who has no idea what has been done, again a very silly practice.

    Mine { 1996 } has been on the book and it showed faulty sensors and I replaced the 4 at a considerable cost , it still does it.What next, replace the whole set up which is probably worth more then a disco 1 is now.Incidentally it is the only thing that I have had constant trouble with in 12 years of ownership.

    I understand your dilemma, but you need to find someone who knows these systems inside out to fix it. Removing a globe and masking a fault is wrong.
    The other alternative is to remove the whole ABS system, brake lines and all, and revert to non ABS and get an engineer to approve it, as it WAS optional equipment. I agree the system isn't exactly a 'good' one, but as far as insurance goes, which is the main point I had, it must be functional if on the vehicle.
