	Risk of accident  when commissioning the vehicle due to a lack of braking effect when the service brake is operated for the first time after repair work.	Before starting the engine, actuate brake pedal several times until pressure is built up and maintained in the brake system.	AS42.50-Z-0002-01A
	Risk of injury  . Skin or eye injuries may result when handling hot or glowing objects.	Wear protective gloves, protective clothing and safety glasses, if necessary.	AS00.00-Z-0002-01A
	Risk of injury  caused by scraping or cutting body parts on sharp vehicle parts	Always wear protective gloves when working on or near sharp and non-deburred vehicle parts. Deburr repair panels.	AS00.00-Z-0017-01A
	Risk of poisoning  from swallowing brake fluid. Risk of injury from skin and eye contact with brake fluid	Only pour brake fluid into suitable and appropriately marked containers. Wear protective clothing and eye protection when handling brake fluid.	AS42.50-Z-0001-01A

	Remove/install
1	Remove cover over brake fluid reservoir.	Install cover only after checking brake fluid level.
2	Clean area around cap of brake fluid reservoir.	Assembly cleaner	*BR00.45-Z-1028-04A
3	Remove cap of brake fluid reservoir and suction off some brake fluid.	This prevents the brake fluid reservoir overflowing when the brake piston is pushed back.
4	Remove front wheel and tire assemblies.	Model 217.377/378/379 with code B07 (AMG - ceramic brake system) Model 222.177/178/179 with code B07 (AMG - ceramic brake system)	AR40.10-P-1102A

6.1	Check condition of brake disks (1).	Model 217.377/378/379 with code B07 (AMG - ceramic brake system) Model 222.177/178/179 with code B07 (AMG - ceramic brake system) If there is a problem, ↓ replace brake disks (1).	AR42.10-P-0270RG
6.2	Check condition of brake disks (1).	Model 231.474/479 with code B07 (AMG - ceramic brake system) If there is a problem, ↓ replace corresponding brake disk (1).	AR42.10-P-0270RG
7	Release and disconnect right front brake lining wear sensor electrical connector (S10/2x1).	Only when removing brake linings (2) on right side.
8	Press back brake pistons with pusher tool.	Attach pusher tool to the elevations (A) of the brake linings (2). Secure remaining brake pistons to prevent them slipping out. Resetting device	Fig 1
		Wedge If there is a problem, ↓ Replace brake caliper (3).	Fig 2

9	Remove screws (4) then remove brake caliper support (5) together with brake caliper (3).	Do not unscrew screws (9) completely. Do not separate brake caliper (3) and brake caliper support (5). Otherwise an optimum alignment of the brake caliper (3) to the brake disk (1) can no longer be guaranteed, which results in higher wear and an incorrect contact pattern. Replace screws (4).

10	Remove brake caliper (3) and secure to vehicle free of tension.	Do not crush, kink or stretch brake hoses (6) and brake lines. This leads to damage to the brake hoses (6) and brake lines, and it can impair their function. Model 217.377/378/379 with code B07 (AMG - ceramic brake system) Model 222.177/178/179 with code B07 (AMG - ceramic brake system) The brake line pieces (99) of the brake hoses (6) must not be bent. Replace the affected brake hoses (6) with damaged brake line pieces (99) immediately. Do not damage paint of brake caliper (3). If brake line piece (99) is damaged, ↓ replace affected brake hose (6).

11	Remove brake linings (2) from brake caliper (3).	Do not apply brake pastes or other lubricants to brake linings (2) and brake caliper (3). Malfunctions may occur otherwise. Do not release or pull out the studs (7), push brake linings (2) against force of retaining springs (8) of the studs (7). Only sets of brake linings (2) approved by Mercedes-Benz may be installed.
	Check
12	Check brake caliper (3) and dust boots for leak tightness.	If there is a problem, ↓ Replace brake caliper (3). Model 231.474/479 with code B07 (AMG - ceramic brake system)	AR42.10-P-0070RK

13	Check retaining springs (8).	If there is a problem, ↓ Replace retaining springs (8).
	Clean
14	Clean contact surfaces of brake linings (2) on brake caliper (3).	Do not use sharp-edged or pointed objects. Otherwise, the brake caliper (3) or the dust boot on the brake piston may be damaged. Assembly cleaner	*BR00.45-Z-1028-04A
15	Pull right front brake lining wear sensor (S10/2) out of backing plate of brake lining (2).	Only when removing brake linings (2) on right side.
16	Install in the reverse order.
	Concluding tasks
17	Press brake pedal several times until brake linings (2) lie up against brake disks (1).	Firm resistance should be noticeable at the brake pedal.
18	Check/correct brake fluid level in brake fluid reservoir.
