Had my rear brake lines changed a few weeks ago, entire pipes up to the engine bay and I'm not entirely sure my ABS is working correctly now. Had a bit of a run down the avenue at home and each time I braked I got a little skid at the end and audible tyre squeal.
I didn't feel any judder in the pedal but realistically my not have been going fast enough. Any suggestions as to how else I might test it. I'm assuming a pebble road or even a wet field would be a better choice...
