Brakes 'falter/hestitate' when approaching standstill

Try bleeding the brakes maybe it's never been done If not scan your car carefully and look at the freeze frame data when you're breaking I don't think there's any real hand off from regen to hydraulic It's kind of all working at the same time when the pedal gets to a certain point some people break so lightly they never ever use the hydraulics in these vehicles It can be done.

 

Does your brake actuator cycle frequently? If so, your symptoms are not uncommon for when an actuator is failing.

 

My first guess is that you have "rust jacking" of the front wheel speed sensors. Corrosion forms under the sensor mounting flange and over time pushes the sensor body slightly away from the axle tone ring.

This extra gap causes the speed signal for that wheel to be some weaker than normal, so the ecu sees the speed (falsely) "drop out" as you come to a stop. It then activates the ABS as a response.

Carefully remove the front sensors (don't snap the 6mm bolts off!). Then clean all the corrosion from the steering knuckle where the sensor mounts.

This is very interesting to know. One more thing to check and stay ahead of when doing brakes!

 

Check the discs for run out too. If they are out of spec, it will add weight to getting the discs replaced along with the pads.

 

Every time I pull the sensors out of the front hubs they're always covered with little whiskers of iron or whatever they're like magnetic and I mean the thing is just covered it's unbelievable I spray it off with the brake clean or whatever wipe off the end of the sensor with the shop towel make sure it's all clean and spray off the tone ring blow it off with the air hose towards the ground put the sensor back in but every time I have a front wheel off a night take a look because it only takes a second they're just coated with well little pieces of metal iron whatever no matter what I do.

 

Are the dust covers still present?

 

Funny you should ask that. One car the dust covers this is for the front now The dust covers and shields are in place. On the other car when I replace the front hubs I did not put the backing plates back on that go behind the rotor and onto the face of the strut or whatever face of the hub I'm sorry. And both cars look about the same it's lots of little what would look like tin whiskers in an audio device. But heavier slightly and more iron looking is all I can say and I just blow it off with electrical contact cleaner not overly saturating any of the business and then blow it off with my shop air which is turned down generally and that's that But it doesn't seem to make any difference in the way the brakes operate to be honest about it but I always find this mess on the end of the sensor seemingly regardless of when I check it If I cleaned it yesterday and went out and looked at it tomorrow they'll be some build up on it already. And the tone ring looks fine It seems to be self cleaning by wind water and whatever car movement.
