Rear locking easily
« on: 29 August 2012, 11:32 »
I've got no ABS in my car, hate the thing so I disabled it. However my rears lock up far before the fronts, causing the rear to step out under heavy braking. As the Mk3's haven't got a brake compensator valve, how can I turn the bias towards the front? Is there any way?

I'm sure I've read that the bias valve is part of the ABS system hence why you've now this issue. I'm guessing an inline manually adjusted  bias valve would resolve it though.

IIRC lower spec and early GTIs had rear brake compensators.

They did. Mine is 1995 though. No valve. I know a manual bias valve would sort it, but don't they require the brake lines to run through the cabin so you can have the valve at hand?

Just a thought but I assume you have checked sticky calipers etc.

No need to run it through the car, just set it up right...  Would probably be easier to get an early spec compensator fitted and set that up correctly.  Or just put your ABS back on.

Think one side is sticking a tad at the rear. From what I've been reading though the rear will always lock up first as the system is designed to work with ABS. Sucks.

Rather get a valve and adjust it to my liking. Think it's something I'm going to just stick with really, can't be chucking more money at the car!

Don't worry, I'm used to rear braking only  :wink:

Different on a track mind you.

Switching off your ABS has caused the biasing to be disabled. Very dangerous.
