🔧 Challenger - Rear Brake Pad Replacement

Rear pad replacement on your Challenger depends on which rear calipers you have. The SRT 392 is commonly equipped with fixed Brembo rear calipers (pads retained by pins), but some cars use a sliding (single-piston) rear caliper.

Difficulty Level: Intermediate | Estimated Time: 1.0-2.0 hours

⚠️ Safety & Precautions

• 🛑 Work on level ground and chock the front wheels before lifting the rear.
• 🛑 Support the car with jack stands—never rely on a floor jack alone.
• 🛑 Do not press the brake pedal while calipers/pads are removed.
• 🛑 Brake dust is harmful—avoid compressed air; use brake cleaner.
• 🛑 Keep the parking brake released during the pad swap.

📋 Before You Begin

• Park on level ground, leave the transmission in gear, and release the parking brake.
• Loosen rear lug nuts 1/2 turn before lifting (use 21mm socket and breaker bar).
• Open the hood and check the brake fluid reservoir level; pushing pistons back can raise the level.
• Two quick questions so I give you the exact factory-correct steps and torque specs:
• ❓ Do your rear calipers say Brembo and use two visible pad-retaining pins across the face of the caliper?
• ❓ When you look at the rear caliper, do you see one piston (sliding caliper) or multiple pistons on both sides (fixed caliper)?
