Title: ABS Removal
Post by: dturpin on May 31, 2012, 04:09:18 PM
Hello everyone, me and my mate are turning my FD into a track day car, and are in the process of stripping it down.  We would like to remove the ABS, I know that we will need a biasing valve, I have pictures of people using the one off the abs unit, is this ok to do, or should I buy a fully adjustable one?
Other than that I am struggling to find a thread on how to actually remove the whole abs system, including wiring and the abs ecu?
If anyone could direct me to a thread if there is one about, or if someone would be willing to write it up on here for me would be greatly appreciated.
Cheers Dave

lots of work mate...why don\'t you just remove the fuse?...... I had a vx220 and its common issue that the abs is over sensitive, whip fuse out and system off. ......plus the fd abs is not over sensitive.  if the abs light dont come on and go off will be an MOT failure soon if she goona be road legal.......good luck with it i\'ve only just started tracking mine and mucho FUN!

Abs CPU is located behind the left side panel in the boot, remove the unit and follow the wiring. I done this when the whole car was stripped so very easy tracing the wiring, otherwise it would be difficult.

Its a lot of work, you would need to:

Remove every single ABS line
Remove ABS pump
Remove all wiring to the ABS pump
Change the master cylinder for a non ABS model
Remove all ABS sensors
Remove ABS ECU

If its not going to be MOTed its fine, but the options for ABS for a MOT are either 100% complete and working or not there at all.

You could legally have ABS sensor still - as you might be using them for traction control such as racelogic, but I should imagine you\'d have to remove the extra brake plumbing

Thanks for all the help.  It\'s not going to be road legal so mot\'s won\'t be an issue, we are hoping to eventually enter some competions in it, so would like to totally remove it for weight aswell as that it won\'t be needed on a track.

if you need it only for a track car then you will need,
a 10 mm tee piece and 3 unions and some copper brake pipe and a flaring tool,thats about it,
you have to basically run one pipe from the master cylinder to the rear brake union on the nsf bulk head(by fuel pipes),then run the other part of the cylinder to a tee where one goes to nearside front and one goes to offside front,theres prob a how to somewhere

....and the braking feel is very much improved by removing it too

Talking to a mate of mine who does mot\'s and I said we use the abs trigger points for TC - He said if it has the trigger points on then it would fail the test as its part of the ABS system (again, needs to be on 100% or 0% as Mitch says)

Totally daft :censored:
