Brake Component Overview, FN3
• Install the complete repair kit.
• After replacing the brake pads, depress the brake pedal firmly several times with the vehicle stationary so that the pads are properly seated in their normal operating position.
• To extract brake fluid from the brake fluid reservoir use a bleeder bottle which is used only for brake fluid. Brake fluid is poisonous and must on no account be siphoned out by mouth using a hose!

2 - Bolt, 10 Nm
• M6 x 12
3 - Brake hose
• Do not disconnect the brake hose when changing brake pads.
4 - Bracket
• Bolted to brake caliper housing.
5 - Bolt, 10 Nm-
6 - Spring clip
7 - Brake line
• Tightening specification for brake line at the bracket: 15 Nm.
• Tightening specification for brake line at the brake caliper: 15 Nm.
• Install one end into brake caliper housing.
• Install one end into brake hose, counter hold on brake hose hexagon.
• Make sure that the lugs are properly seated in the grooves in the bracket.
8 - Connector
• Remove from bracket when replacing brake pads.
9 - Ribbed bolt, 190 Nm
• Clean ribs if using again
10 - Brake carrier
• Bolt to wheel bearing housing
11 - Brake pads
• The inner surface (with tension spring) is indicated by an arrow. The arrow must point in the direction of brake rotor rotation when moving forward. If installed incorrectly this may cause noise problems.
• Clean the guide surfaces and apply a thin coating of polycarbamide grease (G 052 142 A2) before inserting pads.
• There is an adhesive foil on the back plates of the brake pads. The protective foil must be pulled off before inserting.
• Brake pad wear indicator (left front and right front).
• Warning lamp in the instrument cluster will light up when the wear limit (2 to 3 mm) is reached.
• Always replace both sides.
• Removing and installing, refer to => [ Brake Pads, FN3 ] Brake Pads, FN3.
• Check pad thickness.
• Always clean the brake caliper (grease free) before inserting new brake pads. When doing this, make sure that all adhesive foil residue on the contact surfaces for the outer brake pad is removed.
12 - Retaining spring
• Before inserting the pads, clean the guide surfaces and apply a thin coating of polycarbamide grease (G 052 142 A2).
• Insert the springs into both holes in the brake caliper housing
• After inserting the retaining spring into the two holes, press it under the brake carrier. If incorrectly installed, it is not possible to adjust the wear of the outer pad, and the pedal travel will be increased as a result.
