ABS problem!!

[snipe202]

1993 mk4 TT auto coupe
the wheels lock up instantly when i touch the brakes, not depending on pressure applied.

think it started after recent right shock change...

any ideas guys? :(

Possibly some sort of damage to ABS sensor or wiring when removing the shocker? Wire may have stretched and internally broken?

I dont know how thats possible. By design ABS limits the force applied to the brakes to stop locking up. I dont know how it could make it lock up with barely any pressure?

Sounds like you have fractured or damaged an ABS sensor lead to me.

The system thinks a wheel is already locked as it sees no signal from the damaged ABS sensor or lead.

But if it cant see a wheel locking, it wont limit its force....

yeah that makes sense... ok thanks for the input guys, I'l get the ABS sensors checked :)

yeah but it shouldnt make the wheel lock up instantly when he touches the brakes. I can understand it if he was braking moderatley or hard but just touching and locking them up?

Damaged ABS sensor/wire.
