🔧 Edge - Rear Brake Pad Replacement

You’ll remove the rear wheels, retract the electronic parking brake (EPB), compress the rear caliper piston, then swap in new pads and hardware. On your Edge, the EPB must be put into a service/maintenance mode so you don’t damage the caliper or EPB motor.

Difficulty Level: Intermediate | Estimated Time: 1.5-3 hours

---

⚠️ Safety & Precautions

• ⚠️ Support the Edge with jack stands on solid, level ground—never rely on a floor jack alone.
• ⚠️ Use EPB Maintenance/Service Mode before pushing the rear pistons back, or you can damage the EPB system.
• ⚠️ Do not press the brake pedal while a caliper is off the rotor.
• ⚠️ Avoid breathing brake dust; use brake cleaner instead of blowing with air.
• 🔋 Battery disconnect is not required, but keep the key/fob away from the vehicle so the EPB can’t auto-apply.

📋 Before You Begin

• Park on level ground, steering straight, and place wheel chocks at the front wheels.
• Release the parking brake and keep the key/fob away from the Edge while you work.
• Check brake fluid level; when you compress pistons, fluid rises. Use a catch pan and don’t overfill.
• Put the EPB into service mode using one of the options below.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Put the EPB into Maintenance/Service Mode

• Preferred (scan tool): Connect your scan tool with EPB service function (specialty) and run the Rear EPB Service/Brake Pad Replacement Mode to retract the parking brake motors.
• Notes: This is the safest method. “Service mode” retracts the EPB so the piston can be pushed in normally.
• Tip: Write down any on-screen prompts.

Step 2: Loosen rear lug nuts

• Use a 21mm socket with a breaker bar to crack loose the rear wheel lug nuts about 1/2 turn (don’t remove yet).

Step 3: Lift and secure the rear of the Edge

• Use a floor jack (rated 3-ton minimum) to lift the rear at the approved lift point.
• Set the vehicle onto jack stands (rated 3-ton minimum).
• Give the Edge a gentle shake to confirm it’s stable.

Step 4: Remove the rear wheels

• Remove lug nuts using the 21mm socket, then remove both rear wheels.

Step 5: Remove the rear caliper (pads stay in the bracket)

• Turn the steering knuckle by hand if needed for access (rear is limited; reposition your body instead).
• Locate the two caliper slide pin bolts on the back of the caliper.
• Use a 7mm hex bit socket with a 3/8" ratchet to remove the slide pin bolts.
• Lift the caliper off the bracket and support it using a brake caliper hanger hook (never let it hang by the hose).

Step 6: Remove old pads and hardware

• Pull the inner and outer pads out of the bracket by hand (use a flathead screwdriver gently if stuck).
• Remove the stainless pad clips from the bracket using the flathead screwdriver.
• Clean the bracket pad lands (where the clips sit) with brake cleaner and a small wire brush.

Step 7: Service the slide pins (important for even braking)

• Pull the slide pins out of the bracket by hand.
• Wipe them clean, then apply a thin coat of brake caliper grease (silicone).
• Reinsert pins and confirm they move smoothly. (A “slide pin” is the guiding pin that lets the caliper float and self-center.)

Step 8: Compress the rear caliper piston

• Remove the brake fluid reservoir cap under the hood (this reduces pressure). Use a rag around it.
• Use a brake piston compressor tool to slowly push the piston straight back into the caliper.
• If the piston will not compress smoothly, stop—EPB may not be fully retracted.
• Tip: Go slow to avoid fluid overflow.

Step 9: Install new hardware and pads

• Install new stainless pad clips into the bracket by hand.
• Apply a very thin film of brake caliper grease (silicone) where pads contact the clips (not on pad friction material).
• Install the new inner and outer pads into the bracket.

Step 10: Reinstall caliper and torque fasteners

• Lower the caliper over the new pads.
• Install the slide pin bolts using the 7mm hex bit socket.
• Torque to 28 Nm (21 ft-lbs).

Step 11: Reinstall wheels and torque lug nuts

• Reinstall wheels and hand-thread lug nuts.
• Lower the Edge off the stands using the floor jack.
• Use a torque wrench with a 21mm socket to tighten lug nuts in a star pattern.
• Torque to 135 Nm (100 ft-lbs).

Step 12: Exit EPB service mode

• Use the scan tool with EPB service function (specialty) to run EPB Close/Exit Service Mode.
• You may hear the rear EPB motors run briefly—this is normal.

✅ After Repair

• With the Edge still parked, press the brake pedal slowly 8-12 times until it feels firm.
• Check brake fluid level and top off only if needed (use the correct DOT brake fluid listed on the reservoir cap).
• Test the EPB apply/release function with the EPB switch.
• Road test at low speed first. Verify no grinding, pulling, or warning lights.
• Pad break-in: make 6-10 gentle stops from 30 mph to 5 mph, letting brakes cool between stops.
