handbrake light & ABS light

[Screech16v]

When the hand brake light is on ,for those without the bias unit on the rear axle it can  mean that your brake bias is not working so you have equal pressure to all wheels. not good if your going round a bend and then have to stamp on them,could lock up the rears and spin you out.

Getting a code reader on tuesday so will let you all no the outcome. With regards to the bleed nipples iam gona keep soaking them in wd40 till Tuesday  then have a go at them when more than likely i need to change a few abs sensors. If i remember I'll take plenty of pics of what i do for a how to

If the handbrake light is showing constanly then it means the ABS controlled brake bias is not working.

Non ABS mk3s have a brake bias valve on the rear axle (controls front and rear brake balance). On late mk3s with ABS, the system controls brake balance.

Basicly your ABS ECU has packed up so you have no brake balance system which is bad.

Everything was working fine till i changed discs pads and r/o/s caliper. Ive ordered new front abs sensors. Might as well do them all while iam at it.
For the rear sensors do i just need the sensor like the fronts or do i need the long lead aswell? I have a 3 door and read that its only 5 door that has connector under the seat is this right?

If abs ecu has packed in is this a hard job to fix?

Five mins to change the ECU as long as the bolts dont round off, its finding an cheap exact replacment thats hard,
