Brake Caliper, Removing And Installing: Removing
The procedure only applies to the replacement of or subsequent repair work done on the brake caliper.
Do not disconnect the connectors from the parking brake motors.
-- Remove the wheel from the affected rear side.
The pistons on the electro-mechanical parking brake must be driven back using the Vehicle Diagnostic Tester.
Before pressing the piston back, extract the brake fluid from the brake fluid reservoir. Otherwise the brake fluid will overflow and cause damage, especially if the brake fluid was added intermittently.
-- Drive back the piston with the Vehicle Diagnostic Tester.
-- Remove the bolts -arrows- for the parking brake motor.
-- Remove the parking brake motor and set aside, without disconnecting the connectors.
-- Attach the bleeder bottle bleed hose -1- to the brake caliper bleed valve.
-- Open the bleeder valve.
-- Insert the :VAG1869/2 .
-- Close the bleeder valve and remove the bleeder bottle.
-- Remove the brake hose.
There is a risk of injury because the spring is tensioned.
The spring can jump out and cause eye or skin injury.
- Hold the spring with a hand.
-- Using the screwdriver -A-, pry off the brake pad spring -1- from the brake caliper -arrow-, while doing so secure the spring with the other hand.
-- Remove the caps -arrows-.
-- Remove both guide pins from the brake caliper using the :T10503 and :VAS6784 .
-- Remove the brake caliper from the brake carrier.
