🔧 Malibu - Rear Brake Pad Replacement

On your Malibu, the rear pads sit inside the rear calipers and wear down over time. Replacing them is straightforward, but many Malibus use an electronic parking brake (EPB), which must be put into “service mode” before you compress the caliper piston.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• ⚠️ Support the car with jack stands; never rely on a jack alone.
• ⚠️ If your Malibu has electronic parking brake (EPB), retract it with a scan tool (service mode) before pushing the piston in—forcing it can damage the caliper/EPB motor.
• ⚠️ Avoid breathing brake dust; use nitrile gloves and safety glasses.
• ⚠️ Don’t press the brake pedal while a caliper is off the rotor.

📋 Before You Begin

• Park on level ground, shift to P, and place wheel chocks at the front wheels.
• Confirm whether you have an EPB button on the console (a “P” with a circle). If yes, plan to use a scan tool EPB service mode.
• Loosen rear wheel lug nuts slightly using a 19mm socket and breaker bar before lifting.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Retract the electronic parking brake (if equipped)

• Connect your scan tool with GM EPB service mode (specialty).
• Command the rear parking brake into Service Mode / Retract (wording varies by scan tool).
• If you’re unsure, stop and ask. Forcing the piston can damage the EPB system.

Step 2: Lift the rear and remove the wheels

• Lift the rear with a floor jack (rated 3-ton minimum) and support with jack stands (2-ton minimum).
• Remove the lug nuts with a 19mm socket and 1/2" drive breaker bar, then remove both rear wheels.

Step 3: Remove the rear caliper

• Turn the steering wheel is not needed (rear), but position yourself for access.
• Remove the caliper slide pin bolts using a 13mm socket and 3/8" drive ratchet.
• Lift the caliper off the bracket and support it using a brake caliper hanger hook (do not let it hang by the hose).

Step 4: Remove old pads and hardware

• Pull the inner and outer pads out by hand; use a flat trim/pry tool gently if stuck.
• Remove the stainless pad clips from the bracket using a flat trim/pry tool.
• Clean the bracket pad lands with a wire brush and spray with brake cleaner spray.

Step 5: Service the slide pins

• Pull the slide pins out of the bracket by hand; use nitrile gloves.
• Wipe them clean and inspect the rubber boots for tears.
• Apply a thin, even coat of brake caliper slide pin grease (silicone) and reinstall the pins so they move smoothly.

Step 6: Compress the caliper piston

• Before compressing, make sure EPB is retracted (if equipped).
• Use a brake caliper piston compression tool to slowly push the piston straight back into the caliper.
• Go slow—fast pushes can overflow fluid.

Step 7: Install new hardware and pads

• Install new pad clips from the rear brake hardware kit (clips) into the bracket by hand.
• Install the new pads into the bracket. Make sure they slide freely in the clips (no binding).

Step 8: Reinstall caliper and torque fasteners

• Place the caliper over the new pads.
• Install the slide pin bolts using a 13mm socket and 3/8" drive torque wrench.
• Torque to 35 Nm (26 ft-lbs).
• If you removed the caliper bracket (only needed for rotor replacement), reinstall bracket bolts using an 18mm socket and 1/2" drive torque wrench and Torque to 130 Nm (96 ft-lbs).

Step 9: Reinstall wheels and lower the car

• Reinstall wheels and hand-thread lug nuts.
• Lower the vehicle from the jack stands using the floor jack.
• Tighten lug nuts in a star pattern using a 1/2" drive torque wrench.
• Torque to 140 Nm (103 ft-lbs).

Step 10: Exit EPB service mode (if used)

• Use the scan tool with GM EPB service mode (specialty) to command Apply / Exit Service Mode.
• Verify the parking brake applies and releases normally.

✅ After Repair

• Pump the brake pedal 10–15 times until it feels firm (this seats the pads).
• Check brake fluid level and top off only if needed.
• Road test at low speed first; confirm normal braking and no warning lights.
• Pad bed-in: do 6–10 moderate stops from 50→15 km/h with cool-down between.
