2	Remove floating caliper (34) from caliper support (33)
	Disassemble/assemble
3	Carefully press out piston (47) using compressed air; remove piston with piston rotating pliers if necessary	Install using pliers if necessary.	Figure
		Model 202.033/093, model 208.374 and model 210.072 with CODE 957 E 50 AMG 210.074/274 are fitted with a 2-piston floating caliper. If piston is rusted tight (47), replace floating caliper (34).
		Installation:  Coat cylinder bore with brake fluid.
4	Remove dust cap (45) from floating caliper (34)	Installation:  Put dust cap (45) over piston (47) and insert into cylinder bore together with piston. Push in piston using both hands. Ensure correct seating. Floating caliper and repair kit must be from same manufacturer.
5	Remove piston seal (50) from the groove in the cylinder bore.	Installation:  Coat new piston seal (50) with brake fluid. Floating caliper (34) and repair kit must be from same manufacturer.
6	Check piston (47) and cylinder bore of floating caliper (34), and replace if necessary
