BMW M2 CS CCB Brake Caliper Dust Boot Set OEM 34117845750

The BMW M2 CS CCB Brake Caliper Dust Boot Set — OEM (Part No. 34117845750) is a genuine BMW set of six front caliper piston dust boots for the F87 M2 CS Carbon Ceramic Brake (CCB) system — the gold-painted six-piston front caliper fitted to M2 CS models equipped with the optional CCB package. One package covers one front caliper. Essential maintenance for any M2 CS owner running the CCB system, particularly for track use.

Why CCB Dust Boots Are a Maintenance Item

Carbon ceramic brake systems operate at temperatures that dramatically exceed the thermal range of conventional steel-rotor brake systems. On a track, the M2 CS's CCB front calipers routinely reach temperatures above 400°C — a thermal cycle that over time degrades the rubber dust boots protecting each caliper piston's sealing surface. Degraded boots allow brake dust, water, and debris into the piston bore, accelerating seal wear and eventually causing caliper piston sticking or uneven pad wear. BMW specifies dust boot inspection and replacement as a maintenance item on CCB-equipped vehicles used in track applications — and the OEM rubber specification is the correct material for the M2 CS CCB caliper's operating envelope. For extreme or frequent track use, see the High Temp Silicon version.
