I've noticed that my T8 brakes seem to be very touchy or grabby. There is very linear brake feel during braking, then all of a sudden its like the car wants to slam to a stop, more noticeable when not under heavy braking. Has anyone else experienced this or something similar? Is this a normal brake feel for a hybrid?

This is my second T8, first being a MY16 T8 that was bought back, but I don't remember the brake bite feel being this exaggerated.

Mine feel a bit inconsistent as well. I forget if there's an adjustment available in the driver profile, but there might be.

This brake feel is the same using normal and dynamic braking adjustments.

Mine is a 2016 so can't speak to the new ones. Are you talking about the transition between the regenerative braking and friction brakes? There is a noticeable difference in feel when the friction brake engages but it is still linear and very controllable.

I'm specifically referring to friction brakes being overly touchy/grabby.

In Eco mode on my T6, the engine is very eager to shut off at low speeds, so there?s a kind of kerplop from 3MPH or so to zero. Maybe you?re experiencing the engine shutting off?

I have a MY17. I only notice sticky brakes when they're damp or wet and haven't been used enough to clear the water off of the rotors or pads or whatever. This is usually resolved within a few full stops. This is the same with any vehicle I've ever owned.

So I do not usually notice either the RBS or regular brakes feeling more responsive than they should. I also do not notice a big difference when transitioning from RBS to regular braking. I do feel like I have to apply more force to the brakes in this vehicle (and the T6s I've driven) when at a full stop than I have in other vehicles I've owned but I assume that's just the way Volvo designs their brakes.

I am shopping for an xc90. I have done test drives on two 2018 T6's and a 2017 T8. For the T6, braking is completely controllable on every tap on it. For T8, I felt the car does not respond/slow down exactly to the force applied on the brake for the first 1-2 seconds. Not sure if this is overall T8 brake behavior, or very specific to 2017 T8. I did not get a chance to try out on a second T8, as no other T8 on the lot.

Likely different electronic bias due to regenerative braking. When I run my car in "B" mode the brakes feel better I assume because of the added resistance of the regeneration w/ the electric motors. Also when in performance mode the brakes are noticeably improved with less pedal effort required for the same stopping power.

New T8 owner here. Brakes feel a little spongy at first but it will grab eventually. I can adapt to this even though the braking effort is not entirely linear.

Is yours 2018 model year?

Not totally linear, but not touchy or grabby to me. Driving a loaner T5 compared to my T8 there is a difference, but not huge. Most hybrid or cars that regenerate battery on braking having the same feel.

'17 here, not _exactly_ linear - but I can get the feel for it. Feathering it to keep it in regen vs. pads-on-rotors is a challenge, especially as you are coming to a stop. But using "B" for slower/neighborhood driving seems to help. I do seem to roll though a few stop signs though.

. Yes, in my signature line.

So due to some unfortunate software update timing and/or a bad battery or something in some component of my Volvo On Call system, I've been spending a bit more quality time then I'd like with some loaner XC90s. Both of them have been T6s (2017 and 2018) where mine is a 2017 T8. As far as braking is concerned, I don't notice much of a difference in the stopping distance, force required to achieve that, or the ability for the brakes to hold at a full stop. There's a little but not much. I will say that in all cases, there is more force needed to keep the vehicle stopped then I'm used to in other makes/models. I do not use the auto brake feature as it's not to my liking. Also, when comparing the T6 Dynamic mode to the T8 Power mode, the T6 feels like it's more rearing to go when releasing the brake even a little vs. the T8. In the end, mashing the throttle is more responsive on the T8, but the amount of torque at idle is higher on the T6.

In comparison to my immediate prior vehicle which was also a hybrid, I am glad that the T8 has the B gear position. My last vehicle essentially operated in this B gear position at all times unless its "Tow Mode" was engaged which disabled the RBS and forced the ICE to run - so not very efficient. So I had about seven years of being used to a vehicle that would slow down when I took my foot off of the throttle. When I first got the T8, I felt like I was a bit out of control until I realized what B mode was and that I could drive in it all the time.
