Aftermarket ABS

    Nearly hit a fox coming home from work last night, he darted from a bush onto the road and I jammed on, wheels locked up instantly and I was kinda scared by how little the car slowed down. Luckily the noise of the skid caused the fox to quickly turn around.
    Anyway, car is an 03 fiesta, drum brakes. Is this even possible? Cost effective?
    Any experience?
    Thanks

    nada

    far better off flogging it and buying something else.......

    personally I would never buy a car without abs.

    nah , not really worth it... disc brakes are more affordable... 100's of places sellimg them or just buy em from england :rolleyes:

    Google cadence braking. It gives the same effect as ABS, though not as efficient obviously. Great for staying in control on wet roads during severe braking though.

    You braked instinctively, fair enough. You over-reacted though. When the wheels lock up, your brakes are not as effective, and you risk losing control. You should consider practising emergency stops (on a clear, dry road naturally!).

    Also, braking in this manner for a fox (or dog, or cat) is wrong. Better that the animal is killed than you put yourself or other road users or pedestrians at risk. What if there had been another vehicle behind you for instance. You should consider your options - steering round the obstacle for one. If you jam on, you are then committed.

    I know I am off-topic from your question re aftermarket fitting of ABS (not on AFAIK - too much involved), but I think you are a 'new driver', so hope you take my suggestions in the spirit in which they are intended.

    [edit] Drum brakes at the rear, btw. Discs front.

    Not your ornery onager

    You didn't mention road conditions but it would be worth checking your tyre tread depth to ensure that its well above the legal minimum. Effective braking also requires that your shock absorbers are in good condition and that your brakes are well maintained (are the rear drums doing their fair share of work?) Might be worth checking the car out before doing too much else. Your wheels will lock up more easily under heavy braking if the items above need attention.

    Your steering is not as effective. But your braking doesn't get any better than when the wheels are locked up as there is max friction between tyre and road.

    Nothing will stop you in a shorter distance than a good ole lock-up, it's a pity steering doesn't work during it.

    OP, if you want to be able to steer under heavy breaking better off getting a car with ABS. If you want to decrease your stopping distance tho you need wider/better tyres.

    ABS could be transplanted from a Fiesta that has it, but it's a huge amount of work. No such thing as aftermarket.

    All cars had to have ABS fitted as standard since 1999 I think so the Fiesta shoudl have it already. It might not be working. Better to check that out first.

    Actually ABS was made manditory on new cars sold in the EU from 2004.

    This is not strictly true, friction is slightly greater just before the tyre loses grip. That said, on most surfaces there's not a lot in it - as you say, being able to steer is the big plus with ABS.

    Fiesta has front discs. Always did.

    ABS cannot be retro fitted economically.

    Nope my 2003 Focus Zetec doesn't have it either. Which is odd considering the base Golf had it in 98 IIRC. Was only fitted as standard in anything below a Focus Ghia from late 03!

    All Cars since the 60s have Disc Brakes
    the might have Drums on the back
    but as 70% of ur braking is done by the Front it doesnt really matter


  • Registered Users Posts: 2,399 ✭✭✭kluivert


    My 1999 Astra has ABS. I twould be one of things I would look for when buying a car alright.

    Saved my ass a few times, likewise with bloody small animals running out of the hedges.

    Near sure I ran over a frog the other evening as well. I felt really bad about it for some reason.

    You never came across a 1977 VW Beetle 1200 or a 1980 Mini so... Both have drums all round.

    The majority of braking may be done by the front but its vital that braking force between front and rear of the vehicle is balanced. If rear braking efficiency is compromised then the fronts will lock more easily as the driver applies more braking pressure.

    The Ghia model had it from 99 if I'm not mistaken(and a great car it is too), or was it 01 when Ford made the Ghia badge worthy of it's name in the Focus and fitted equipment(i.e. aircon, alloys etc) as standard?

    Ford were always very late to the party on safety equipment(Ghias and high spec models excluded), which is so odd since they were the first to fit the drivers airbag as standard on a mass market relatively affordable car an incredible 15 years ago in the Mondeo:eek:.

    Actually in the wet it can be hugely higher before grip is lost, but 99.9% of drivers won't be able to maintain that point just before grip is lost, especially in an emergency.

    But anyway, the point I was really making is that ABS improves steering, not stopping distance.

    The initial batch of MkI VW Golfs (1974/75/76) had drum brakes on the front.

    OP - As others have already stated, forget about it. The cost of retro fitting ABS would easily upgrade you to a model that has it fitted as standard.

    They were the first to have ABS as standard across a model range with the Mk 111 Granada.

    Anyone remember the ABS fitted to some '80's Escort/Orions? pump driven by a belt from the driveshaft...:eek:

    True but it can be messy!

    I always felt I stop quicker without ABS. ABS feels like its preventing you from applying the brakes fully. Which it is of course.

    Instead of buying ABS or a car just with ABS. Consider buying a car with better brakes. Sports cars generally have better brakes than standard cars.

    Better in the sense that they can better withstand repeated heavy braking. If the brakes are strong enough to lock up the wheels then no further advantage would be conferred by stronger brakes. Better tyres might be an idea, though.


  • Closed Accounts Posts: 18,056 ✭✭✭✭BostonB


    Would they not lock up the wheels faster though? I take your point though bigger is mainly about heat.

    I suppose what i should have said is that sports cars can generally stop quicker than a non sports car.


  • Registered Users Posts: 6,831 ✭✭✭Alkers


    Jeez this has gone OT. For those suggesting investing in better brakes then that's completely off the ball, surely that would result in the wheels locking even faster and would have a negative result on the overall stopping distance. Some people really ought to read the thread before jumping on the bandwagon...
    Cadence breaking sounds like the works but it would surely also be uneconomical bearing the mind the amount of training it would take for it to become your natural reaction.
    Road conditions were wet but not raining.
    Selling the car for a better model is not an option as the car isn't mine and is exceptionally low millage.
    Car and tyres are in good condition so no faults there.
    A lot of people are jumping out making it out as if I have done something wrong here, all I've done is witnessed the maximum breaking force under pressure with me as a driver and questioned how I can improve on it. I think a lot of people ought to lighten up and offer advice rather than criticism. AS I've said before conditions were wet and the fox jumped out of a hedgerow so I couldn't have seen him earlier.
    Thanks for the imput, it seems that aftermarket ABS isn't a possibility and I won't go looking down that road.
    Thanks for those that posted constructively.


  • Closed Accounts Posts: 18,056 ✭✭✭✭BostonB


    ..and fitting ABS isn't off the ball? :D

    Fitting bigger brakes is often done as is bigger wheels and better tyres.

    Changing cars to get one that brakes better doesn't seem OT to me at all.


  • Registered Users Posts: 6,831 ✭✭✭Alkers


    So it's possible to fit aftermarket ABS?
    IMHO fitting bigger brakes would have been of no improvement as the wheels would have locked up even quicker (with me at the wheel) than they did in the above example...
    As I've said changing cars is OT as it's not my car to change, I'm only a named driver.


  • Registered Users Posts: 22,306 ✭✭✭✭Esel


    OP, learn and practice cadence braking. It's easy. And don't brake hard for small furry animals - at least not on wet roads.

    In the incident you described with the fox, you lost control of your vehicle. Address this issue rather than carp about people going OT (which I didn't notice btw - most threads here digress somewhat).

    - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

    For large animals (cows, horses, deer), police drivers are taught a counter-intuitive technique which could well save their life, as well as the life of any passengers.

    Basically, you have braked hard but know you are going to hit the animal. What you do is stop braking and floor the throttle! This raises the front of the car substantially. You still hit the animal, but instead of it mounting the bonnet and entering the vehicle and probably killing or seriously injuring you, it is ploughed out of the way instead. You may well be injured, but hopefully not dead.

    Not your ornery onager

    This is all well and good and I appreciate your input (in this and other threads) esel, but I wasn't looking for criticism (constructive as it may be) on my driving, I was asking about the ABS.
    I don't see your above technique working at all when (as I was) in fifth gear (in a 1.2L car), where accelerating as hard as possible wouldn't raise the front of the car at all. It's also extremely hard to learn to the extent where it becomes a natural reflex, especially where to consider the time where you evaluate the life of a child over that of a dog etc in the split seconds it takes you to make an emergency breaking manouvre.

    Nothing to evaluate there, dog get it every time, as unfortunate as that may be.
    You started this thread obviouslly interested in finding out if a method of stopping the car more safley was worth investing in. It's not worth it to get ABS fitted to a car aftermarket, extravagently expensive.

    However someone has pointed out a safer way to apply the breaks, which is worth doing. I have used it before myself, I was in a Opel Corsa (instructors car) and locked up the breaks, I had the breaks released and re-applied before the instructor could react to the inciednt, and that was the one and only time I have ever used that breaking technique. it works and it is easy to do, you just have to remember to do it when the wheels lock up, which basically means concentrating, which you should be doing anyway.

    OP I am not having a dig at you, just posting my experince, take from it what you will.

    had the car serviced recently ? brakes checked ? are your pads worn ? have you got decent tyres i put some cheap tyres on my car and then changed to semperit comfort life and it changed the cars braking completely (the old ones were about 4mm)
