9.2	Unscrew bolts (36) and remove brake caliper (31a) with brake caliper support (31b)	MODEL 212, 218 The brake caliper (31a) and brake caliper support (31b) must always be removed together as a complete unit and should not be separated. It will otherwise no longer be possible to guarantee optimum alignment of the brake caliper (31a) to the brake disk (61). This can then result in greater wear and an incorrect contact pattern. Replace the bolts (36). The bolts (35) securing the brake caliper (31a) to the brake caliper support (31b) must not be loosened.
		Self-locking bolt, brake caliper support to steering knuckle	*BA42.10-P-1008-10J
10	Secure brake caliper (31a) to vehicle free of tension	Do not kink the brake hose or subject it to tensile loads. Otherwise damage will occur. Do not damage paint of brake caliper (31a)
11	Remove brake pads (43) from brake caliper (31a)	Do no loosen or remove screw bolts (41) Press the brake pads (43) off the screw bolts (41) against the force of the retaining springs (31d). Brake pads (43) are to be disposed of as special waste. The local authorities can provide information regarding whether disposal is also permitted as industrial waste similar to domestic waste. Do not apply brake pastes or lubricants to the brake pads (43) and brake calipers (31a). Only complete sets of brake pads (43) approved by Mercedes-Benz may be installed.
	Check
12	Check brake calipers (31a) for leaks and dust boots for damage	Install new brake calipers (31a) if necessary.
13	Check retaining springs (31d) for deformation and correct seat	If necessary, replace retaining springs (31d).
	Clean
14	Clean contact surfaces of brake pads (43) on brake caliper (31a)	Do not use sharp-edged or pointed tools to clean. Otherwise damage may occur.
