How to Replace Rear Brake Pads and Rotors on a 2016 GMC Savana 2500
Step-by-step DIY instructions with tools, parts list, torque specs, and parking brake (drum-in-hat) tips


đź”§ Savana - Rear Brake Pads & Rotor Replacement
You’ll remove the rear wheels, take off the rear brake calipers and brackets, replace the pads and rotors, then reassemble and bed-in the new pads. On your Savana, the parking brake is typically a small “drum-in-hat” setup inside the rear rotor, so the rotor may be held up by the parking brake shoes if they’re adjusted too tight.
Difficulty Level: Intermediate | Estimated Time: 2-4 hours
Assumption: Rear disc brakes with drum-in-hat parking brake (common on Savana 2500).
⚠️ Safety & Precautions
- 🛑 Work on level ground; use jack stands—never rely on a jack alone.
- 🛑 Chock the front wheels with wheel chocks so the van can’t roll.
- 🛑 Brake dust is unhealthy—use brake cleaner, not compressed air.
- 🛑 Do not press the brake pedal with a caliper removed.
- 🛑 Keep grease and oil off pad/rotor friction surfaces.
- 🛑 Battery disconnect is not required for this job.
đź”§ Required Tools
You'll need the following tools for this repair:
- Floor jack (rated 3-ton minimum)
- Jack stands (rated 3-ton minimum)
- Wheel chocks
- Safety glasses
- Nitrile gloves
- Breaker bar (1/2")
- Torque wrench (1/2", 20-200 ft-lbs range)

- 18mm socket
- Ratchet (3/8" or 1/2")
- Flat-blade screwdriver
- C-clamp (6" minimum)

🔩 Required Parts
HowToo sells all the parts you need for this repair:
- Rear brake pad set - Qty: 1
- Rear brake rotors - Qty: 2
- Brake cleaner spray - Qty: 2
- Silicone brake lubricant - Qty: 1
- DOT 3 brake fluid - Qty: 1 bottle
- Rear caliper hardware kit (clips/shims) - Qty: 1

đź“‹ Before You Begin
- Park on level ground, shift to P, and turn the engine off.
- Release the parking brake fully (you’ll be removing rotors that sit over the parking brake shoes).
- Crack the rear lug nuts loose using a 22mm socket and breaker bar before lifting.
- Open the hood and loosen the brake fluid reservoir cap (this helps the pistons retract). Place a rag around it to catch any overflow.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Lift and secure the rear of the van
- Chock the front wheels using wheel chocks.
- Lift the rear using a floor jack (rated 3-ton minimum) at the rear jacking point.
- Set the van down onto jack stands (rated 3-ton minimum) under the frame.
Step 2: Remove the rear wheels
- Remove the lug nuts using a 22mm socket and ratchet.
- Set wheels aside under the van as an extra safety backup.
Step 3: Remove the rear caliper (and support it)
- Turn the steering is fixed in rear; just work straight-on at the caliper.
- Remove the caliper slide/guide pin bolts using a 13mm socket and ratchet.
- Lift the caliper off the pads.
- Hang the caliper with a bungee cord so it doesn’t dangle by the brake hose. (A bungee cord is just a stretchy strap used to hold parts out of the way.)
Step 4: Remove the old brake pads and hardware
- Pull the pads out by hand; use a flat-blade screwdriver if they’re stuck.
- Remove the pad abutment clips/hardware from the bracket using a flat-blade screwdriver.
- Clean the bracket pad “rails” with brake cleaner spray and a wire brush.
Step 5: Remove the caliper bracket
- Remove the caliper bracket bolts using an 18mm socket and breaker bar.
- Set the bracket aside.
- On reassembly: Torque to 148 Nm (109 ft-lbs).
Step 6: Remove the rotor (and deal with the parking brake shoes if needed)
- Pull the rotor straight off the hub.
- If the rotor is stuck from rust, strike the rotor “hat” area with a rubber mallet (avoid the wheel studs).
- If it still won’t come off, the parking brake shoes may be holding it:
- Make sure the parking brake is fully released.
- Use a flat-blade screwdriver through the access slot (if equipped) to back off the star adjuster a few clicks.
Step 7: Prep the hub and install the new rotor
- Clean the hub face with a wire brush so the rotor sits flat (this helps prevent pedal pulsation).
- Clean both sides of the new rotor with brake cleaner spray to remove packing oil.
- Install the new rotor onto the hub.
Step 8: Service the slide pins and install new hardware
- Pull the caliper slide pins out of the bracket by hand.
- Wipe them clean and apply a thin coat of silicone brake lubricant.
- Install the new abutment clips/hardware onto the bracket.
- Thin grease only—don’t glob it on.
Step 9: Reinstall the caliper bracket
- Position the bracket over the new rotor.
- Install bracket bolts by hand first, then tighten using an 18mm socket and ratchet.
- Torque to 148 Nm (109 ft-lbs) using a torque wrench (1/2").
Step 10: Compress the caliper piston
- Place one old brake pad against the piston face.
- Use a C-clamp (6" minimum) to slowly push the piston back into the caliper. (A C-clamp is a screw clamp that presses the piston in smoothly.)
- Watch the brake fluid level at the reservoir—remove some into a small drain pan if it starts to overflow.
Step 11: Install the new pads and reinstall the caliper
- Install the new pads into the bracket.
- Set the caliper over the pads.
- Install and tighten the guide/slide pin bolts using a 13mm socket and ratchet.
- Torque to 41 Nm (30 ft-lbs).
Step 12: Repeat on the other rear wheel
- Do the same steps on the other side. Rear brakes should be replaced in pairs.
Step 13: Reinstall wheels and torque lug nuts
- Install wheels and hand-thread lug nuts.
- Lower the van off the stands using the floor jack (rated 3-ton minimum).
- Torque lug nuts in a star pattern using a torque wrench (1/2"):
- If your Savana has 8-lug wheels: Torque to 190 Nm (140 ft-lbs).
- If your Savana has 6-lug wheels: Torque to 140 Nm (103 ft-lbs).
âś… After Repair
- With the engine OFF, pump the brake pedal 10-15 times until it feels firm (this seats the pistons against the new pads).
- Check brake fluid level and top off with DOT 3 brake fluid if needed.
- Test the parking brake holds the van on a gentle incline; if it doesn’t, the parking brake shoes may need adjustment.
- Do a careful test drive: start with slow stops in a safe area.
- Pad bed-in (basic): make 6-10 moderate stops from ~30 mph to 5 mph, letting brakes cool a bit between stops. Avoid hard stops at first.
- Recheck lug nut torque after 25-50 miles using a torque wrench (1/2").
