	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	Remove cover over brake fluid reservoir.
2	Clean area around cap of brake fluid reservoir.	Assembly cleaner	*BR00.45-Z-1028-04A
3	Unscrew cap of brake fluid reservoir and suction off some brake fluid.	This prevents the brake fluid reservoir from overflowing when the brake pistons are pushed back.
4	Remove front wheels.		AR40.10-P-1102A
5	Expose electric line of front right brake lining wear sensor, then release and disconnect electrical connector.	When removal of brake linings (2) at front right.
		Ensure electric line of front right brake lining wear sensor is routed correctly.
6	Press back brake pistons slightly using pusher tool.	Position the pusher tool at the elevations (arrows) of the brake linings (2).
		Resetting device	Fig 1
7	Remove bolts (5).	Replace screw/bolts (5).
		Bolt, brake caliper to steering knuckle	*BA42.10-P-1001-10BA
8	Unhook brake hose (6) from holder on steering knuckle or on suspension strut.
9	Remove brake caliper (1) from steering knuckle and secure to vehicles with lines still attached free of tension.	Do not subject the brake hose (6) and electric line to tension and do not kink them. The brake hose (6) and the electric line can otherwise be damaged.
10	Press brake linings (2) off screw bolts (4) against force of retaining springs (3) 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) and the brake caliper (1). Only sets of brake linings (2) approved by Mercedes-Benz may be installed.
	Check
11	Check retaining springs (3) for damage and condition.	If there is a problem, ↓ replace the retaining springs (3).
12	Check brake linings (2) for wear and condition.
		If there is a problem, ↓ replace brake linings (2) in sets.	AP42.10-P-4252I
13	Check condition of brake disks on front axle.		AR42.10-P-0270RG
		If there is a problem, ↓ replace corresponding brake disk.	AR42.10-P-0230FRK
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-0070FRK
15	Press back brake pistons all the way using pusher tool.	Attach pusher tool onto brake piston. Secure remaining brake pistons using two wedges against slipping out.
		Wedge	Fig 2
		Resetting device	Fig 1
		If the brake piston is sluggish, ↓ replace brake caliper (1).
			AR42.10-P-0070FRK
	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. The brake caliper (1) or the dust boots of the brake pistons can otherwise 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 lines (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 disks.	Firm resistance should be noticeable at the brake pedal.
	Check
20	Check/correct brake fluid level in brake fluid reservoir.
			AP42.10-P-4210B
21	Perform brake test on test stand.
