Brake Caliper, Replacing, Ceramic Brakes: Installing
Install in reverse order of removal and note the following:
Replace the brake caliper bolts.
-- Clean the brake carrier on the contact surfaces -arrow- for the brake pad springs.
-- Install the brake pad springs and pay attention to the installation position while doing so.
-- If reusing, install the marked brake pads in the same location.
-- Insert brake pads in brake carrier.
Make sure the brake pads are seated in the brake pad springs -arrows-.
-- Install the electromechanical parking brake motor. Refer to LEFT/RIGHT PARKING BRAKE MOTOR -V282- / -V283-, REMOVING AND INSTALLING .
-- Push the brake caliper over the installed brake pads.
If the previous brake pads are being reinstalled, the electrical wire for the brake pad wear sensor must be guided through the brake caliper.
-- Tighten the new brake caliper bolts -arrows- by counter-holding the guide pins -1 and 2-.
Make sure that the brake pad wear sensor fits correctly in the brake pad.
-- Secure the brake pad wear indicator wire with the dust cap -4- as shown.
-- Bring the connector into its installed position and turn in the direction of the -arrow- until the tab -1- engages in the hole -2- on the bracket.
-- Connect the connector -3-.
-- Install the brake hose -1- in the brake caliper and tighten.
-- Check the retaining spring -3- for damage and replace if necessary.
-- Insert the brake hose into the bracket -arrow- and connect it to the brake line by tightening the union bolt -2-.
Make sure the brake hose is routed correctly.
Make sure the brake hose is not blocked, bent, twisted or rubbing against the vehicle.
-- Connect the connector -arrow- to the electromechanical parking brake motor.
-- Remove the :VAG1869/2 .
-- Drive the parking brake motors up using the Vehicle Diagnostic Tester by following the instructions in the display.
-- Only bleed the brakes on the wheel from which the brake caliper and the brake hose was loosened. Refer to HYDRAULIC SYSTEM, BLEEDING .
It must be bled on each bleeder screw. Bleed the brake caliper with two bleed screws first on the inner screw.
If the brake pedal still feels "soft", completely bleed the brakes.
-- Install the rear wheel, while observing the safety precautions for vehicles with ceramic brakes. Refer to WHEELS AND TIRES .
Risk of accident!
- With the vehicle stationary, firmly press the brake pedal several times so that the brake pads in the operating condition properly sit in their respective position.
- Make sure the brakes are working correctly before driving the vehicle for the first time.
