	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 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	Open service flap above expansion reservoir for brake fluid.
2	Clean area around cap on brake fluid expansion reservoir.	Assembly cleaner	*BR00.45-Z-1028-04A
3	Unscrew cap on brake fluid expansion reservoir and suction off some brake fluid.	This prevents the expansion reservoir overflowing when the brake piston is pushed back.
4	Remove front wheels.		AR40.10-P-1102A
5	Expose electric line of front right brakepad wear sensor, then release and disconnect electrical connector.	Ensure that electric line of front right brake lining wear sensor is routed correctly.
6	Press back brake pistons slightly using pusher tool.	Position pusher tool at the elevations (arrows) of the brake linings (2). Resetting device	Fig 2
7	Remove screws (5).
Notice	Notes on threaded connections fastened using a tightening angle-based tightening process		AH00.00-P-0020-01A
		: Replace screw/ Bolts (5).

8	Unhook brake hose (6) from holder at steering knuckle and suspension strut.
9	Remove brake caliper (1) from wheel carrier and secure it free of tension to vehicle with lines connected.	Do not subject brake hose (6) and electric line to tension and do not kink them. The brake hose (6) and the electric line may otherwise be damaged.
10	Press brake linings (2) against force of retaining springs (3) off screw Bolts (4) and remove from brake caliper (1).	Do not release or remove screw Bolts (4). : Do not apply brake paste or lubricants to brake linings (2) or brake calipers (1). Only install brake linings (2) approved by Mercedes-Benz as a set.
	Check
11	Check condition of retaining springs (3) and Check for damage.	If there is a problem, ↓ Replace retaining springs (3).
12	Check brake linings (2) for wear and Check their condition.

13	Check brake discs on front axle.		AR42.10-P-0270RG
		If there is a problem, ↓ replace corresponding brake disc.	AR42.10-P-0220EWE
14	Check brake caliper (1) and dust boots of brake piston for leak tightness and damage.	If there is a problem, ↓ Replace brake caliper (1).	AR42.10-P-0070LWC
15	Press back brake pistons with pusher tool.	Attach pusher tool onto brake piston. Secure remaining brake pistons using two wedges against slipping out. Wedge	Fig 3
		Resetting device If the brake pistons can only be moved sluggishly, ↓ Replace brake caliper (1).	Fig 2
			AR42.10-P-0070LWC
	Clean
16	Clean contact surfaces of brake linings (2) on brake caliper (1) and on brake pistons.	Do not use sharp-edged or pointed objects. Otherwise, the brake caliper (1) or the dust boots of the brake pistons may be damaged. Assembly cleaner	*BR00.45-Z-1028-04A
17	Pull front right brake lining wear sensor out of backing plate of brake lining (2).	When replacing brake linings (2) or when replacing front right brake lining wear sensor. Pay attention to installation location of front right brake lining wear sensor.
18	Install in the reverse order.
19	Operate brake pedal several times until the brake linings (2) make contact with the brake discs.	Firm resistance should be noticeable at the brake pedal.
	Check
20	Check/correct brake fluid level in expansion reservoir.
