• Reduced braking response from thin friction material
• Brake warning light service needs when paired with the correct wear sensor
• Routine front brake service on OE-style BMW applications

Confirm rotor condition, caliper hardware condition, and pad fitment against the vehicle before installation. Part number 2551-1561-00 is for the front position only.
