1500 - Front Brake Pad Replacement 🛠️

Got it—you want to replace the front brake pads on your 2015 1500 (4WD, SLT). I’ll walk you through it step by step, beginner-friendly.

Quick questions before you start:

• 🧰 Do you have a solid, level place to work (not dirt/grass)?
• 🛞 Are you planning to replace pads and rotors together (recommended), or pads only?

I’ll assume you’re doing pads only for now and note where it changes if you add rotors.

1500 - Safety & Prep ⚠️

• 🧯 Safety first:
  • Wear safety glasses and mechanic gloves.
  • Use a floor jack and jack stands (jack stands = metal supports that hold the truck safely once lifted).
  • Never work under a truck supported only by a jack.
  • Keep the truck in PARK with the parking brake ON and chock (block) the rear wheels.

1500 - Tools & Parts Needed 🧰

• 🔧 Basic tools:
  • Floor jack (2+ ton) and 2 jack stands.
  • Wheel chocks (or bricks/wood blocks) for rear wheels.
  • Lug wrench or 1/2" drive ratchet with 22 mm socket (typical Ram lug size).
  • Ratchet + sockets: 13 mm and 21 mm (caliper and bracket bolts).
  • Open/box wrench: 13 mm (for caliper slide pin if it spins).
  • Torque wrench (tool that lets you tighten bolts to a specific torque).
  • C-clamp or disc brake piston tool (to push the caliper piston back).
  • Flat screwdriver or small pry bar.
  • Wire brush (to clean rust from bracket).
  • Bungee cord or wire (to hang the caliper).
• 🧴 Supplies:
  • New front brake pads (for your 2015 1500 4WD).
  • Brake cleaner spray.
  • High-temp brake grease (for slide pins and pad contact points).
  • Shop towels/rags.
• 📏 Torque specs (front):
  • Caliper guide pin bolts: ~26 ft-lb (35 N·m).
  • Caliper bracket bolts: ~130 ft-lb (176 N·m).
  • Wheel lug nuts: 130 ft-lb (176 N·m) in a star pattern.

1500 - Front Brake Pad Replacement Steps 🚗

1. Prepare the truck

• 🧱 Park on a flat surface, set parking brake, and put the shifter in PARK.
• 🧱 Chock both sides of at least one rear wheel.
• 🔧 Slightly loosen the front wheel lug nuts (about 1/2 turn) while the truck is still on the ground.

2. Lift and support the front

• 🛠️ Place the floor jack under the front crossmember (strong metal beam under the front).
• Lift until both front wheels are off the ground.
• Place jack stands under the frame rails on both sides and lower the truck onto them.
• Give the truck a shake to be sure it’s stable.

3. Remove front wheels

• 🛞 Remove the lug nuts and take off both front wheels.
• Set wheels under the frame as an extra safety backup if you like.

4. Access the front caliper

• 👀 Turn the steering wheel to the side you’re working on (left for left, right for right) to give more room.
• Locate:
  • Caliper – the part that squeezes the pads.
  • Caliper bracket – the larger bracket bolted to the steering knuckle.
  • Two caliper guide pin bolts on the back (usually 13 mm).

5. Compress the piston slightly (optional but helpful)

• 🧰 Before removing bolts, you can gently pry the caliper outward using a flat screwdriver between pad and rotor to relieve some pressure.
• Do not slip and damage the rubber boot around the piston.

6. Remove the caliper

• 🔧 Remove the two caliper guide pin bolts (13 mm).
• If the pin spins, hold the flat on the pin with a wrench while loosening the bolt.
• Carefully slide the caliper off the pads and rotor.
• Hang the caliper with a bungee cord or wire from the spring or frame; do not let it hang by the brake hose.

7. Remove old pads & hardware

• 🧹 Pull the inner and outer pads out of the bracket.
• Remove the stainless pad clips (hardware) from the caliper bracket if your new pads come with new clips.
• Inspect the rotor:
  • Deep grooves, cracks, or heavy rust = replace rotors.

8. Clean and prep the bracket

• 🧴 Spray the caliper bracket and rotor surface (not bearings or rubber) with brake cleaner.
• Use a wire brush to clean the areas where the pad clips sit until shiny metal shows.
• Install new stainless pad clips onto the bracket (they should snap in firmly).
• Apply a thin film of brake grease on the areas of the clips where the pad ears will slide. Do not get grease on pad friction surface or rotor.

9. Service the slide pins

• 🛠️ Pull the caliper slide pins out of the bracket (one at a time).
• Wipe off old grease and inspect the rubber boots for tears.
• Apply fresh high-temp brake grease to the pins and reinsert them, making sure they move smoothly.

10. Compress the caliper piston

• 🧰 Remove the master cylinder cap under the hood (brake fluid reservoir) and place a rag around it in case fluid rises.
• Place an old pad against the piston face inside the caliper.
• Use a C-clamp or piston tool to slowly push the piston fully back into the caliper housing.
• Watch the fluid level in the reservoir; if it gets too high, remove a little with a clean syringe or turkey baster.

11. Install new pads

• 📦 Compare new pads to old ones to confirm shape and size.
• Install the inner pad and outer pad into the bracket, making sure:
  • Pad ears fully seat in the clips.
  • Any wear indicator (small metal tab) matches the original pad position (usually inner pad).
• Apply a very thin layer of brake grease on the back of the pads where they contact the caliper/piston (not on friction surface).

12. Reinstall the caliper

• 🔧 Slide the caliper over the new pads and onto the bracket.
• Install the caliper guide pin bolts by hand first to avoid cross-threading.
• Tighten with a ratchet, then torque to 26 ft-lb (35 N·m).

13. (If replacing rotors)

• 🛠️ Remove the caliper bracket bolts (21 mm) and take off the bracket.
• Remove the rotor (may need a rubber mallet to tap it loose).
• Clean the hub face with a wire brush, install new rotor, and hold it with a lug nut.
• Reinstall the bracket and torque the bracket bolts to 130 ft-lb (176 N·m).
• Then continue with pad and caliper steps above.

14. Repeat on the other side

• 🔁 Always replace brake pads on both front wheels as a pair.

15. Reinstall wheels

• 🛞 Put the wheels back on and hand-thread all lug nuts.
• Snug them in a star pattern with the truck still on stands.
• Jack the truck slightly, remove jack stands, and lower it to the ground.
• Torque lug nuts in a star pattern to 130 ft-lb (176 N·m).

16. Final steps & bedding in

• 🦶 Pump the brake pedal slowly until it feels firm (this seats the pads against the rotors).
• Check brake fluid level and adjust to the “MAX” line if needed, then reinstall the cap.
• Look around both front wheels for any leaks or loose parts.
• For the first drive:
  • Do a few gentle stops from 30–40 km/h to bed in the pads.
  • Avoid hard braking for the first 200–300 km if possible.

1500 - Extra Tips & Warnings 🚨

• 🧪 Never use oil or regular grease on brake parts—only high-temp brake grease.
• 🧴 Don’t breathe brake dust; use brake cleaner and let it drip onto a pan or cardboard.
• 🧠 Work on one side at a time so you can look at the other side as a reference if you get confused.
