Bleeding Sequence

WARNING: This page is about a different car, the 2016 Audi A3 and 2015 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.

1 - Left Front Brake Caliper

2 - Right Front Brake Caliper

3 - Left Rear Brake Caliper

4 - Right Rear Brake Caliper

NOTE:

Bleed the brake caliper at each bleed screw. If the brake caliper has two bleed screws, bleed the outer screw first.

-- With the bleeder bottle hose attached, leave the brake caliper bleeder valve open long enough so that the brake fluid flows out free of bubbles.

-- Tighten the bleed screw, remove the bleed hose and put the protective cap on the bleed screw.

-- Repeat the bleeding procedure in the specified sequence for the remaining brake calipers.

-- Fill the brake fluid reservoir under consideration of brake pad wear up to the max marking and install the cap.

-- Start the engine and check the brake pedal travel and pressure.

-- If the pedal travel is too long, check the brake system for leaks or repeat the bleeding procedure.

-- Fill the brake fluid reservoir with brake fluid up to the "max" mark.
