🔧 Q5 - Front Brake Pads & Rotors Replacement

Replacing your Q5’s front brake pads and rotors means removing the front wheels, unbolting the brake calipers and carriers, swapping the rotors, and installing new pads with proper torque and a short bedding-in (break-in) drive. On your Q5, parts and torque specs can change depending on which front brake package (rotor size) you have.

Difficulty Level: Intermediate | Estimated Time: 2-4 hours

⚠️ Safety & Precautions

• ⚠️ Work on a flat, solid surface; never rely on a jack alone.
• ⚠️ Support the vehicle with jack stands at the proper lift points.
• ⚠️ Brakes create dust; wear dust mask and avoid blowing dust with air.
• ⚠️ Do not let the brake caliper hang by the hose; support it with a caliper hanger hook.
• ⚠️ Brake fluid can damage paint; wipe spills immediately.

📋 Before You Begin

• Park on level ground, steering wheel straight, and set the parking brake.
• Loosen the front wheel lugs slightly using a 17mm wheel lug socket and breaker bar before lifting.
• Open the hood and locate the brake fluid reservoir; you’ll monitor the level during piston compression.
• Please answer these 2 quick questions so I can give you the exact parts + torque specs:
  • What is your front rotor diameter (stamped on the rotor hat, or measure across the rotor face): 330 mm, 345 mm, or other?
  • Do you have a front brake pad wear sensor plugged into one pad (usually on one front wheel): Yes or No?

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Confirm your brake package (needed for correct torque + parts)

• Check the rotor size using a tape measure (edge-to-edge across the rotor face), or read the size marking on the rotor hat.
• If there is an electrical wire clipped to a front brake pad, that’s the wear sensor; note which side it’s on.
• Reply with rotor size + sensor yes/no.

Step 2: Lift the front and remove the wheels

• Place wheel chocks behind the rear wheels.
• Lift the front using a floor jack and support with jack stands.
• Remove lug bolts with a 17mm wheel lug socket and breaker bar.
• Torque to be provided after you reply with brake package (wheel lug torque can vary by wheel type).

Step 3: Remove the caliper and pads

• Remove the caliper spring/retainer (if equipped) using a flat trim/pry tool.
• Remove the caliper guide/slider bolts using the correct hex bit socket or Torx bit socket (varies by setup).
• Lift the caliper off and hang it from the suspension using a caliper hanger hook.
• Remove the pads from the caliper carrier.
• If equipped, unplug the wear sensor carefully using a flat trim/pry tool.

Step 4: Remove the caliper carrier (bracket)

• Remove the carrier bolts using the appropriately sized socket and a 1/2" drive breaker bar.
• Torque to be provided after you reply with brake package (these are high-torque fasteners and may be one-time-use).

Step 5: Remove the rotor

• Remove the rotor set screw (if equipped) using the correct Torx bit socket.
• Pull the rotor off; if stuck, tap the rotor hat with a rubber mallet.
• Clean the hub face using a wire brush and spray with brake cleaner spray.

Step 6: Install the new rotor

• Clean the new rotor with brake cleaner spray and shop rags to remove packing oil.
• Install rotor and set screw using a Torx bit socket.
• Torque to be provided after you reply with brake package (set screw torque is small but should be correct).

Step 7: Compress the caliper piston and install new pads

• Compress the caliper piston slowly using a caliper piston compressor tool (specialty); this tool pushes the piston back so thicker new pads fit.
• Watch the brake fluid reservoir so it doesn’t overflow; remove some fluid if needed using shop rags.
• Apply a thin layer of brake lubricant to pad ears/contact points (not on pad friction material).
• Install the new pads.
• Reconnect the wear sensor (if equipped).

Step 8: Reinstall caliper and carrier, then torque everything

• Reinstall the carrier and start bolts by hand, then tighten with a socket and torque wrench.
• Reinstall the caliper slider bolts using the correct hex bit socket or Torx bit socket, then torque with a torque wrench.
• All torque specs will be provided after your 2 answers so you don’t risk under/over-tightening.

Step 9: Reinstall wheels and lower the vehicle

• Install lug bolts by hand first to avoid cross-threading.
• Snug with a 17mm wheel lug socket, then final-torque with a torque wrench after lowering.
• Exact lug torque will be confirmed after brake package.

✅ After Repair

• Before moving, pump the brake pedal 10–15 times until it feels firm.
• Check brake fluid level and top off if needed with the correct fluid (only if it’s low).
• Start the engine and do a slow-speed brake test in a safe area.
• Bed-in the brakes: do several medium stops from 30–40 mph without coming to a complete stop each time, then let them cool.
• If a brake warning light stays on, re-check the wear sensor connection.
