Friction brake noticeable grabbing at low speed braking

I've noticed a little bump when it transitions if im late on the brakes into a corner. It doesn't really change how the car is behaving though so it hasn't really worried me.... if it locked up the brakes id be more concerned.

I paid a bit more attention to mine after speaking with you yesterday, i only really noticed a very subtle difference when the breaks change, but its so subtle i wouldnt have noticed if you didnt mention yours. Keep an eye on it like they said and see how you go. Hopefully its nothing or easily adjusted.

I can feel the change over on gentle braking, but it's not as severe as you describe.

This hard jerk can occur as a result of rust naturally building up over time. You can smooth this out more by braking hard to get rid of the layer of rust. It will help smooth out the transition between regenerative braking and friction braking. This is also the reason Tesla recommends using the friction brakes at least once a day.

Never noticed this in our Seal. It's probably not this, bit I'll raise it just in case. Are you in Sydney or anywhere else that it's been raining a lot since you got the car? Brake discs are cast iron, and rust almost instantly in the wet. This can make the first few braking events after the car has been sitting very grabby. In an EV/hybrid this might be delayed for a bit longer than in an ICE car.

Thank you op + top\_phil. I did consider possibly the brake pads not being bedded in or rust. Coincidentally I did have a look last night after a 40km drive and just now 1 hour after a 10km drive. Both times theres still a noticeable rust layer on the outer and inner rim of the rotors. Not sure if this is abnormal amounts of rust post driving.

It has been wet the past few days (Melbourne) and I have generally been babying the car with very cautious driving hence not engaging in heavy braking, but the first few days of driving was dry and pleasant.

Mine were a little crunchy at first too but were fine after breaking in (unintentional pun)

There are so many posts of people complaining about v harsh brakes especially at low speeds under 26 kmph. I myself had to complain twice and do a test drive with the engineer before they agreed to do a brake bleed and it has fixed the problem more or less B4 that I felt the car is trying to eject me through the windshield everytime I brake softly

Experiment with ESC on and off. Not sure if it's related, but I’ve noticed that when ESC (A button near the top left of the gear shift console) is off, the car allows creep; when it's on, there's no creep at low speed. With ESC on, especially in stop-and-go traffic, the brakes tend to 'grab' during the final part of braking. I’ve adjusted my braking technique to compensate. When ESC is off, braking feels smoother with less grab, but I need to keep applying the brake to prevent creeping forward. Maybe it’s just my imagination…

Update 2: Two days prior to my service appointment, the intensity and frequency of the issue dropped substantially. Perhaps coincidental but the only thing that had changed was drier weather and I had washed my car for the first time including iron wheel cleaner which I sprayed on to the calipers/rotors. Nonetheless I brought it to servicing to get it checked it out. The foreman drove it around and struggled to replicate it other than a couple of events but it was a fraction of the intensity compared to what I have previously experienced. Everything physically looked okay, and the servicing department stated they brought out a brand new seal and was able to replicate the vibrations and knocking during the braking. It was suggested possibly the SEAL has softer control arm brushings as a feature of the car which makes the sensations more noticeable. Whilst I didn't get a definitive answer to why my vehicle was so harsh at the beginning, BYD Waverley Servicing and dealership was very helpful and accommodating in general which is refreshing given the stereotype of poor after care services with BYD I had read in my research. I will continue to monitor for changes. Thanks all
