How to Remove the Brake Pads of an Audi A5?
3 Answers
Here is the method for removing the brake pads of an Audi A5: 1. First, remove the wheels of the Audi A5. 2. Take off the dust cover, disconnect the brake pad sensor plug from the bracket, and unscrew the brake caliper fixing bolts. 3. Then, after removing the brake caliper housing, secure it to the car body with a metal wire to prevent the caliper's weight from pressing on or damaging the brake line. 4. Finally, remove the brake pads from the brake caliper housing. Additional information: Brake pads are consumable items. It is a good habit to regularly check the wear level of the brake pads. To check the wear of the brake pads without removing the tire, tilt your line of sight at a 15° angle to the plane of the wheel hub and look at the gap between the brake pad and the brake disc to assess the wear level. A brake pad in good condition has a thickness of about 1 cm. If the thickness is less than 5 mm, it needs to be replaced promptly.
Last time I replaced the brake pads on my Audi A5 myself. First, I parked on a safe and level surface, engaged the parking brake, and slightly loosened the wheel hub bolts with a tire wrench. Then, I used a hydraulic jack to lift the car and placed safety stands under the chassis before removing the wheel. After taking off the caliper, I noted the positions of the two fixing bolts. A professional tool was needed to push the piston back; otherwise, the new pads wouldn't fit. Cleaning the old grease from the guide pins was crucial, followed by applying some copper-based lubricant to prevent sticking. After installing the new pads, I tightened the caliper bolts to the specified torque as per the manual. Before putting the wheel back on and lowering the car, I pumped the brakes a few times to check the reset. The whole process took about forty minutes. Beginners are advised to watch the repair manual video beforehand and follow along.
As a technician frequently working with German cars, the Audi A5 brake pad replacement follows a standardized procedure. First, securely park the vehicle and loosen the wheel hub bolts before lifting the car with a hoist. After removing the wheel, the brake caliper structure becomes visible, requiring the removal of two mounting bolts. The piston must be evenly pressed back using a dedicated retraction tool to avoid damaging the seals. Before installing new pads, check if the brake disc thickness meets specifications and clean the caliper bracket of dust. The lubrication of guide pins directly affects braking sensitivity and requires specialized silicone grease. After installation, tighten the bolts to the workshop manual-specified torque of 125 Nm. Finally, conduct a road test to check for even braking performance, and it's advisable to evaluate the brake disc condition simultaneously for added safety.
