Abs system pulses when slowing to a stop on dry roads. Why, and what can I do to fix it. This started after I changed the brakes all way round.
Do you
have the same problem?

This happens when an ABS wheel speed sensor is getting weak. To be sure these videos will help us find the problem:

The abs system needs to be monitored with a hand held computer that can read the input from the sensors. The sensors may be fine, but the harness may be at fault. Regardless of the source this is where diagnosing this begins. There will be codes stored in the computer possibly to narrow this down, but getting to see what is being lost is needed. Once the offending circuit is found, testing can then be done on the sensors, harness etc.

Testing is the best way to go about it. You can check the harnesses and do continuity checks as well as the connectors, but it would be far more effecient to check with the scanner to start narrowing down the problem.
