Follow these steps carefully
Work the FRONT axle: single-piston sliding calipers with guide pins hidden under dust caps on the back. Verify pads match the front axle, check rotor thickness against the minimum stamped on the rotor hat, and look for a pad-wear sensor wire before ordering.
Park on level ground and chock the wheels. The electronic parking brake acts on the rear, so no service-mode step is needed. Crack the 17mm wheel bolts before lifting, raise the front onto jack stands, and remove the wheel. Snug hub bores stick when corroded.
Pry the dust caps off and remove the two guide pins. Disconnect the wear-sensor lead if equipped, then hang the caliper with wire. Never strain the hose. Pull the pads and replace any pitted pin and its boot, since pins corrode under their dust caps.
On higher-mileage Q3s I check the guide pins before ordering anything. They corrode under those dust caps, and I have seen a pitted pin drag pads dead in a season, so I always budget for new pins and boots.
Clean the bracket lands and apply anti-squeal paste to the contact points. Install the pads with the hardware oriented as it came out and reconnect the wear sensor. Open the reservoir, then press the piston back with a spreader tool without letting fluid overflow.
Before I press any piston back, I siphon the reservoir down with a turkey baster. The new pads push the fluid level right back up, and overflowed brake fluid eats paint fast.
Tighten the caliper fasteners to 35 N-m and refit the dust caps. Tighten the wheel bolts to 120 N-m in a star pattern. Pump the pedal until firm, check the fluid level and wear-sensor warning, then bed the pads gently for 150-200 km.
Test your repair before closing everything up. If something doesn't work right, double-check your steps.
