This may be a dumb question. One for any brake specialists that might be reading this.

If you pull out the fuse for a vehicle's anti-lock brake system, does it mean that the brake system will operate in a conventional manner?

If so, then it would seem to me that an easy way to overcome the shortcomings of ABS on dirt is to just pull the out its fuse while offroad.

Any thoughts guys?

I know my brother disconnects the ABS on his WRX for Club gymkhana's - not sure how, I think he has installed a 'switch' inside the cabin for a quick 'swap'? I will follow this up for you.Subaru Forester

The guys at DECA in SHapparton have a Falcon with an ABS on and off switch, I think they open circuit the fuse cct for the ABS.

I am not sure though that I would do that in my own car thoLaterally Literal

gdayn savvas.

in most cases if you remove the abs fuse the brake system will work as normal brakes.they design them that way so if something does go wrong with pump ect you still have brakes.jamieson wild cat

Depending on what kind of car you have, you could pull the fuse or fit a ctr difflock switch to the dash if it is an 80 series cruiser.

This exact question was one of my main concerns when upgrading from the faithful old GQ.

I rang a service manager at a Sydney Nissan Dealer. Here is what he "did not tell me".

If you cut into the line on the power side of the fuse and install a switch (use enough cable to mount it where you want it) then you can turn the ABS off with no adverse effect. Unless you count wheel lock up as adverse.

Now I'm not a qualified mechanic or brake specialist or electronics wizz, and you did not here this from me.

I managed to find a near new GU without ABS. Problem solved.

Remember also that you could void your insurance if you disable the ABS.

Rhubarb, if you DON'T disable the ABS on gravel or dirt you WILL need your insurance.

Yes agree with that and think it a bonus to disable ABS offroad. However you do need to keep in mind that insurance companies make there money by not paying you! And will do anything they can to get out of it.

So if you do pull the ABS fuse and have an incident, remember to put it make in before you call the insurance company!

If you learn to brake correctly you will not activate your ABS on dirt. I have trained many people now in a variety of ABS cars and once the threshold braking technique is learned you can brake quickly and safely without activating ABS. You then have no insurance issues or the problem of forgetting to reactivate ABS when your wife goes shopping. Cheers Rob.Cairns Offroad Training & Tours

Dirt, gravel, its the same thing Peter, as I said, learn the correct braking technique and you won't activate your ABS. Like learning how to swim it is a learned skill but once learned is never forgotten. I have taught many people this method now, as you have discovered, ABS on loose gravel is not a good combination and initially caused major problems for me as a trainer. I of course, can not advise people to disconnect thier ABS for insurance reasons. Given a choice, in a vehicle that does a lot of offroad work I would prefer not to have ABS.
