Front Disc Brakes
Front disc brakes are standard on all models. A dual piston front caliper assembly is used on all models except E150. The brake disc and hub is an integrally cast assembly. The disc brake caliper bolts to the front disc brake caliper anchor plate, which bolts to the front wheel spindle. On E150, the caliper bolts to the front wheel spindle and is a pin slider, single piston type. On E250, E350, E450 and E550, the caliper is a pin slider, dual piston type. On all models, the caliper housing has a fluid inlet at the center of the bore. A square section seal fitted into an annular groove in the caliper bore seals against hydraulic pressure, while rubber boots seal the caliper pistons and caliper bore from contamination. The pads are contained within the front disc brake caliper anchor plate and held to the front disc brake caliper anchor plate abutments by disc brake anti-rattle clips. See Fig 1-Fig 4 .
