Question 1

What should you know about the rear Brake Pad Set before starting work and How to ensure proper installation and safety on Audi A3?

Accepted Answer

Keep in mind the hazards of asbestos dust before getting into the work and to make sure that new guide pin bolts are on hand to replace. First of all, choke the front wheels, lift the back of the car and place it on axle stands then take away the rear tires. Should the need be, loosen the handbrake cable and disconnect it at the end of the caliper. Loosen and remove the guide pin bolts with a narrow open ended spanner and dispose of these and fit new ones to replace. Disconnect the caliper, and attach it to the suspension strut using wire making sure it does not (hang freely on the flexible brake hose). Unclip the two brake pads by removing them out of the caliper mounting bracket and removing the pad anti-rattle shims (where present). Test the thickness of all the brake pads; in case any of them are forced to the given minimal limit or even lower, all four brake pads should be replaced. They should also be changed when greasy or oily because they cannot be adequately washed. When the pads are serviceable, carefully clean with a fine wire brush being careful of the sides and back of the metal backing, clean the grooves in the friction material. Make sure that the guide pins move easily in the caliper bracket and that the rubber gaiters are not damaged. Clean the piston and caliper, examine the dust seal, and the piston, checking it against possible leakage and corrosion. In case of the installation of new brake pads, pull the piston back to the full extent, pushing it into the bore of the caliper clockwise, with a pipe attached to the bleed nipple forcing out the displaced fluid into a container. In this procedure, care should be taken to avoid losing braking completely by clamping the caliper flexible hose and opening up the bleed screw. Install the pad anti-rattle shims by inserting them into the caliper mounting bracket making sure they are in the right place and install the pads putting the friction material on the brake disc. Slide the caliper back in place over the pads and connect the new guide pin bolts installing them to the recommended torque but not removing the guide pin. Press the brake pedal more than once until the pads meet the brake disc so firmly that normal pedal pressure is regained. Repeat the same process on the other rear brake caliper, reconnect the handbrake cables, adjust the handbrake, re-fit the roadwheels, lower the vehicle and screw-in the roadwheel bolts as required. Lastly, inspect the level of hydraulic fluid and note that new pads will not reach full braking competency until they bed in, do not hard brake during the first hundred miles after replacement.

Question 2

How to remove and replace the front Brake Pad Set for FS/11 and FN3 brake calipers on Audi A3?

Accepted Answer

In order to get rid of FS/11 calipers, one must first apply the handbrake, jack up the front of the car and place it on axle stands before taking off the front roadwheels. Disconnect the wear sensor wiring of the brake pad, and observe the routing and release it of any attaching clips. Where necessary, open the air deflector shield to access it better. Take the two protective rubber caps off and slacken the caliper guide pins using a hexagon key and then lift the caliper with pads off the hub carrier and then attach it to the suspension strut being careful not to leave the caliper hanging freely on the flexible brake hose. Remember to remove the two brake pads, the inner pad being secured by a spring clip and label the original pads so that they can be replaced later. Check the thickness of each brake pad; in case some are worn to the lowest limit, or are covered with oil or grease, all four pads are to be changed. Clean serviceable pads using a fine wire brush, making sure to clean the grooves and pad locations of the caliper. Ensure that the guide pins move smoothly and look at the dust seal and the piston in terms of damage or leakages. When new pads are being installed, push the caliper piston back against the cylinder with a G-clamp or other such tool, and be careful to control the flow of the brake fluid to prevent any breakage of the master cylinder seals. Install the new pads with the inboard pad labeled as piston side and place the caliper on the brake disc and fit the lug on the hub carrier. Install the caliper guide pins using copper grease and apply the pin to a desired torque without the force being excessive, and may cause the pad spring to deform. Reconnect brake pad wear sensor wiring (where present), and press the brake pedal several times until the normal pedal pressure is regained. Do the same with the other front brake caliper, and re-fit the roadwheels, lower the vehicle, and screw up the roadwheel bolts. The new pads will take time to break-in, and therefore, do not hard-brake in the first hundred miles. In the case of FN3 calipers, one must first start by removing the spring holding the brake pad, the caliper guide pins and then lift the caliper, making sure it is secured in the same manner. Take off the brake pads and observe the position of the pads. In refitting, the outer pad has to be in place against the brake disc then the inner pad with the retaining clip. Fix the guide pins and re-install the retaining spring, and reconnect the wear sensor wiring, when needed. Lastly, release brake pedal until normal pressure has been regained, repeat on the other caliper, replace roadwheels, lower the vehicle and observe the level of hydraulic fluid bearing in mind the bedding-in time of new pads.
