ABS problem on Urq

[Jim Haseltine]

Somewhere in the work you've done one or more of the sensors has been
disturbed and now the ABS unit isn't seeing the same level of signal from
each sensor.
Could also be due to dirt/dust/rust etc on the cv joint teeth.

Sometimes simply resetting the sensors works, other times you have to clean
the cv joint teeth and reset the sensors. If the teeth are badly corroded
the it's time for new joints.

Regards,

Jim Haseltine
