Front brake callipers FN3: Removing and installing Removal:

–  Clamp the brake pedal block -VAG 1869/2- between the brake pedal and the drivers seat and keep the brake pedal pressed during this work procedure. Apply load to depth of approx. 60 mm. Thus the master cylinder valves close and the brake fluid tank does not empty. –  Raise the vehicle. –  Remove wheels. –  Connect the hose of a bleeder bottle to a bleeder screw of the front brake calliper. –  Open the bleeder screw on the front brake calliper to release pressure from the brake system. –  Close the bleed screw.   Note Do not remove the block for the brake pedal -VAG 1869/2-.

–  Remove the protective caps -arrows-.

–  On vehicles equipped with a brake pad wear indicator, unplug connector -1-. –  Slightly lift up locating lug on lower part of connector -2- and turn 90°. –  Pull lower half of connector out of bracket. –  Unscrew brake line from brake calliper → Item.

–  Remove the retainer spring for the brake pads from the calliper housing using a screwdriver as a lever arrow and remove it.

–  Unscrew both guide pins from the brake calliper and remove them.   WARNING Do not apply brake when brake calliper is removed. –  Remove brake calliper from vehicle.   Note Mark brake pads when removing them if they are to be reinstalled. Reinstall in their original position to prevent uneven braking. –  Take out brake pads.   Note Push brake piston into cylinder with resetting tool before inserting brake pads. Before pressing the piston back, draw off brake fluid from the reservoir with a bleeder bottle. Otherwise, fluid can overflow and cause damage, particularly if reservoir has been topped up.

–  Press piston back. Installation Installation is carried out in the reverse sequence; note the following: Always use new bolts → Spare parts catalogue.   Note If applicable, remove soiling and corrosion present on contact surfaces between brake support plate and brake pads.

–  Install brake pad with retaining spring in brake calliper housing (on piston).   Note The inner pad (with spring) has an arrow. The arrow must point in direction of brake disc rotation when moving forwards. Noises can be caused from incorrect assembly. –  Fit outer brake pad onto brake carrier. –  Screw the brake caliper to the brake support plate with the two guide pins, tightening them to 25 Nm. –  Fit the two protective covers. –  Insert retaining spring into brake calliper housing. –  Install brake line on brake caliper → Item and tighten to 15 Nm.   Note After replacing the brake pads, fully step on the brake pedal a few times with the vehicle stopped, so that the pads adapt to their working position. –  Bleed brake system → Chapter. –  Mount the wheels → Running gear, shafts, steering; Rep. gr.44
