How to Replace Rear Brake Pads on a 2018 Audi Q5 (EPB Service Mode Guide)
Step-by-step instructions, required tools/parts, EPB service mode steps, safety tips, and torque spec notes
🔧 Q5 - Rear Brake Pad Replacement
Your Q5 uses an electronic parking brake (EPB) on the rear calipers, so the EPB must be put into “service mode” before you can safely retract the pistons and install new pads.
Once I know how you’ll retract the EPB and which rear brake package you have, I can give you the exact torque specs and the correct step-by-step procedure.
Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours
⚠️ Safety & Precautions
- ⚠️ Do not force the rear pistons in without EPB service mode; you can damage the EPB motors/gears.
- ⚠️ Support the Q5 with jack stands; never rely on a floor jack alone.
- ⚠️ Brake dust is harmful; avoid compressed air and wear a mask.
- ⚠️ Keep the brake pedal untouched while a caliper is off the rotor.
- ⚠️ Keep ignition OFF unless instructed for EPB service mode.

📋 Before You Begin
- Park on level ground, wheels straight, and place wheel chocks at the front wheels.
- Loosen rear wheel bolts 1/4 turn with a 17mm wheel bolt socket and breaker bar before lifting.
- Please answer these 2 quick questions so I can give the exact EPB method + torque specs for your Q5:
- ✅ Do you have a scan tool that supports Audi EPB “Brake Pad Replacement/Service Mode” (examples: OBDeleven, VCDS, ODIS)?
- ✅ Can you upload a clear photo of one rear caliper/rotor (side view), or tell me the rear rotor diameter if it’s stamped (for example, “330 mm”)?
🔨 Step-by-Step Instructions
Follow these steps in order:
I’m ready to lay out the full numbered steps, but I’m holding here because the EPB procedure and several torque specs on the rear brakes vary by brake package. Once you answer the two questions above, I’ll provide the exact, correct sequence (including all Torque to XX Nm (YY ft-lbs) values) for your Q5.
✅ After Repair
- After install, the EPB must be exited from service mode (scan tool), then confirm the EPB applies/releases normally.
- Pump the brake pedal until it feels firm before moving the Q5.
- Test drive at low speed and confirm no pulling, grinding, or warning lights.
