Step-by-Step Replacement Guide

1

Safety & Prep Work

Always work on a level surface. Engage the parking brake and use wheel chocks on non-working wheels.

  • Jack up the vehicle using factory lift points
  • Support with properly rated jack stands
  • Remove wheels and clean brake assembly with brake cleaner
💡 Pro Tip: Pump the brake pedal 10 times before starting to collapse the caliper piston safely.
2

Remove Caliper & Old Pads

Unbolt the caliper mounting brackets. Do not let the caliper hang by the brake hose. Support it with a wire or hook.

  • Remove brake pads and note wear indicators
  • Inspect caliper slide pins for corrosion
  • Clean and re-lubricate slides with high-temp brake grease
3

Inspect & Service Rotors

Check rotor thickness against manufacturer specs. Measure for runout and parallelism.

  • Light rust is normal; heavy scoring or warping requires machining or replacement
  • If replacing, use a thread-locker on wheel nuts (12-15 ft-lbs)
  • Clean new rotors with brake cleaner (do NOT touch with bare hands)
4

Install Pads & Reassemble

Apply ceramic brake paste to the back of new pads and contact surfaces of caliper slides.

  • Push caliper piston back using a C-clamp or piston tool
  • For ABS vehicles, rotate the piston slightly clockwise if required
  • Reinstall caliper and torque bolts to spec (usually 25-35 ft-lbs)
⚠️ Warning: Always bleed brakes if the fluid level dropped below minimum during piston retraction.
5

Bed-In & Test

New brakes require a proper break-in period to transfer pad material evenly to the rotor.

  • Firm pedal pressure: pump brakes 15-20 times before driving
  • Perform 5-10 moderate stops from 45 mph to 15 mph
  • Avoid hard stops or high speeds for the first 200 miles

Critical Safety Checklist

🛡️ Fluid Management

Never mix brake fluid types. DOT 3 and DOT 4 are compatible, but DOT 5 (silicone) is NOT. Contamination causes soft pedals.

🌡️ Thermal Management

Allow brakes to cool completely before disassembly. Hot brakes can ignite brake cleaner or cause severe burns.

🔧 Torque Specs

Always use a calibrated torque wrench. Loose caliper bolts cause vibration, while over-tightening strips threads.

♻️ Disposal

Old pads, rotors, and brake fluid are hazardous waste. Take them to an authorized recycling center or auto shop.

Frequently Asked Questions

How often should I replace brake pads?
Typically every 30,000–70,000 miles depending on driving habits. City driving with frequent stops wears pads faster. Replace when thickness reaches 4mm or you hear squealing wear indicators.
Can I replace just one side's brake pads?
No. Always replace pads in axle pairs (both fronts or both rears). Mixing old and new pads causes uneven braking, pulling, and increased wear on rotors.
Why does my steering wheel shake during braking?
This usually indicates warped or unevenly worn rotors. It can also be caused by glazed pads, improper bed-in, or suspension issues. Machine or replace rotors and ensure proper torque specs.
Do I need to bleed brakes after pad replacement?
Only if you opened the brake line system or the fluid reservoir dropped below the minimum mark, allowing air into the lines. Otherwise, a full bleed isn't required.
