Audi S3 8L Front Discs and Pads Replacement There may have a guide already, but since I started taking photoâs I though about making a full guide, for others to see. Parts and Materials: Pagid Discs x 2 Black Diamond Predator Pads x 4 Plastilube Red Rubber Grease WD40/GT85 or Similar Brake Cleaner Rags/Blue Roll Tools: Rachet 18mm Spanner or Socket T45 Hex Bit Torque Wrench Flat Headed Screw Driver Pry Bar Wire Brush (Small and Big) Caliper Piston Rewinding Tool File Axle Stands Jack 1.Safety First and HandBrake On. 2.Gently Loosen off Wheel Nuts 3.Jack Car Up at your desired location 4.Loosen all Wheel Nuts and Remove Wheel 5.Place Axle Stand at your desired location (Repeat Steps 2-4 for the other side) 6. Remove Caliper Spring with Flat Headed Screw Driver 7. Rear of Caliper you will see two of these (Top and Bottom) 8. Remove Both of these caps 9. Then inside the rubber cylinder is the calliper sliding bolt. Using a T45 Hex Bit with my Ratchet, loosen both bolts and remove 10. Then using my pry bar, I gently forced the calliper away from the pads 11. Once calliper is off, using a bungee cord, support the calliper up in the air and not to place stress onto the flexi hose, as shown. 12. Now you will just have the discs and carrier left and bolted to the hub. Behind and side of the disc is the pad carrier. These are joined to the hub by two 18mm bolts, Spray some WD40 or similar and allow to penetrate. Then I used my 18mm socket with my torque wrench to loosen the bolts as they where very tight and probably havenât been removed for a while. 13. Once Carrier is off, remove the discs holding screw. Then your discs are off. 14. Start to clean up your carrier and hub making sure all traces of rust and dirt is removed. File and wire brush away the dirt. And plenty of brake cleaner. I also used a air compressor with air gun. Clean up the carrier whilst taking care around the dust seal. Used an old toothbrush will some brake cleaner on the dust seal. 15. Then loosen off the brake fluid tank cap and place plenty of blue roll around the cap. Stop any spillages from leaking onto parts. Allows any pressure to escape when you rewind the piston into the caliper 16. Using a Caliper piston Rewinding tool, slowly push the piston back into the calliper. 17. Once done. I then cleaned up the calliper sliding pins and the rubber holders. Then regreased the pins with Red Rubber Grease. Then place the pins back into the holders.
