Hi everyone I am a new to this forum but am after some advice from anyone who has had same issue, I have a f30 335d Xdrive with uprated blue calliper brake system but find the initial bite when applying brakes to be poor so would like to change brake pads for something with a better bite, have spoken to become brakes who recommended yellow stuff brake pads but couldn't guarantee any better bite so at 150 pounds a set not prepared to take risk , gas anybody else had same issue and changed the pads with success, hope someone can help cheers all Addo
