Constant Brake Squealing F36

Hello Guys,

I have a new to me 2015 435i GC M-Sport. The brakes look to be in great shape with smooth rotors and lots of meat left on the pads. The computer says all maintenance is good for some time. The brakes squeal every day whether the car has been sitting and gets driven 1st thing in the morning or after its been driven a while. Is this just the m-sport brakes? If so I will be replacing them with aftermarket when the time comes.

Squealing brakes generally means that the pad is not landing square on the disc and oscillating under pressure. I suggest removing the pads etc. clean the pad and caliper surfaces that the pads locate on and apply silicon grease. Check the caliper piston is moving back and forth easily and not catching on any corrosion in the caliper. Sticky calipers are quite common. Check the locating pins carefully for any sign of wear and replace in necessary. Apply silicon grease to the pins and ensure that they move easily back and forward when located on the rubber grommets in the caliper. [these often harden due to heat and use of copper grease]. If not, replace grommets too. If that doesn't fix it, a disc resurface / replacement and new pads may be required.

Search on the boards, there are numerous threads about this with M-Sport brakes. Also many suggestions for replacement pads to alleviate.
