After I drive in the rain/snow/slush (and let the car dry in the garage overnight, typically) my drivers side front brake is super grabby. It wears off after a few times using the brake. Also, if I am backing out of the garage (again after wet driving and it drying) while reversing and turning left I get a vibration/whine - again after driving it goes away.

So it is possible the disc rusts more than it should? Brakes checked by dealer and said they are OK. Otherwise brakes feel 100%.

I would have them taken apart, cleaned, calipers lubed/serviced all around and put back on by a competent mechanic. this should solve your problem.

mechanics are lazy these days and quality of service has went down. both my car and my friends rotors were put on so shitty, i still had lots of rotor surface left but it was all gone from the outer edges of the rotor so it just needed to be replaced along with the pads.

Seems like lazy affected it. Sad really, that's the bmw dealer too. Seems like they are always looking for things to fix. Lol. Maybe I'll start doing all my own work again!

What do you mean by grabby? Is the car pulling to one side?

What does the whine sound like? What is vibrating?

[vaporblade]

I've worn off the grabbiness after an initial stop at about 10mph. No pulling left at high speeds - ever.

The whining sounds like an old rusty pipe being twisted and causing a harmonic vibration. I'll record it next drive after the wet. It's suppose to snow mid week. 👍

I've been to the dealership before to fix a fuel pump gasket (took over two months, the kids working there put 1000KM onto the car) and another time to fix water damage on the Idrive controller. both times, the car was driven. they also lied to me about when my extended warranty expires. I correct them because I knew the actual date, and they were like "oh yea you have until janurary 2017 then"

anyways, I'm not going back there again I've been doing oil changes every 5000 miles and brakes at my mechanic (who did an excellent job BTW, better then whoever put the original brakes onto the car)

it sounds like there is some rust, or alot of brake dust in between the rotor surface and the caliper causing the brake to grab until it is shaved off the surface from usage. its a little expensive, but if you still have a good amount of brake material left just have a mechanic take all of it apart, clean the rotors, service/lube the calipers and put everything back on properly. if you dont have much brake left, may as well just replace everything with some good OEM stuff..

I wouldnt go back to the dealer ever again.

Recently had a similar problem but it was actually my control arm bushing that was wore out and under braking caused the car to pull to that side.
