Mechanic Sequence

Scan the job path, then open the estimate when pricing is ready.

1 Measure pads and inspect rotors before quoting the final path.
2 Remove caliper hardware, support the caliper, and replace pads and clips.
3 Service slide pins and contact points with proper brake lubricant.
4 Pump the pedal, verify pedal feel, and road test carefully.

Inspection Priority

  • Inner and outer pad thickness on both sides
  • Rotor surface, thickness, scoring, and runout clues
  • Caliper slide pin movement and boot condition
  • Brake fluid level and visible hose or caliper leaks
  • Inspect rotor condition and pad thickness first.
  • Verify inner and outer pad wear pattern.
  • Check caliper hardware movement before quoting pad-only service.
Common repair when wear measurements support it. Inspection recommended before replacement. Multiple causes possible when noise changes with temperature or braking load.

Verify First

Measure pads, rotor thickness, and rotor surface before quoting pad-only.
Check caliper slide movement when wear is uneven.
Separate brake pulsation from hub runout or wheel-end play.

Diagnostic Overlap

  • Pad noise, rotor scoring, seized hardware, and caliper drag can sound similar.
  • Brake vibration can overlap with rotor runout, hub runout, or wheel bearing play.

Repair Evidence

  • Normal pad wear
  • Sticking slide pins or seized hardware
  • Rotor damage or excessive heat spots

Failure Signs & Triggers

Inner pad worn faster than outer pad Rotor scoring, heat spots, or heavy rust lip Slide pins dry, seized, or torn boots Caliper drag after pedal release Brake fluid leak or low reservoir
If Pad wear is uneven Inspect slide pins, caliper piston, and hose restriction.
If Pulsation is present Measure rotor condition and check wheel-end runout.
If Fluid is dark or low Inspect hydraulic leaks and fluid condition.
If Wheel drags after braking Verify caliper, hose, and hardware movement.

Caliper slide inspection Slide condition affects pad wear and repeat comebacks.
Brake fluid inspection Hydraulic condition can explain poor pedal feel or caliper issues.
Hardware inspection Clips and abutments are already accessible.
Measure pads and rotors Confirm thickness, scoring, heat spots, and inner/outer wear. Inspect related systems
Inspect caliper movement Check slide pins, piston movement, hose restriction, and drag. Continue diagnosis path
Check hub runout/play Use when vibration or ABS evidence overlaps brake complaints. Continue diagnosis path

Verification & Tips

  • Torque wheel fasteners
  • Pump brake pedal before moving
  • Confirm pedal feel
  • Check for drag or leaks
  • Replacing pads without inspecting rotor condition
  • Letting the caliper hang from the brake hose
  • Skipping slide pin service

System Context

High Risk Grinding, metal contact, fluid leak, or severe pull
Repair Soon Low pad thickness or uneven wear
Monitor Light noise with pads/rotors still in spec
Verify First Vibration, ABS, or hub symptoms overlap
Rotor condition Brake hydraulic fluid Caliper slides and hoses Tire and wheel access

Next Paths

Brake noise and uneven wear should be inspected before choosing pad-only versus pads-and-rotors pricing.

Verify First

Measure pads, rotor thickness, and rotor surface before quoting pad-only. Confirm before quoting.
Check caliper slide movement when wear is uneven. Confirm before quoting.
Separate brake pulsation from hub runout or wheel-end play. Confirm before quoting.
Brake fluid inspection Check fluid condition when hydraulic or caliper work is likely. Estimate

Brake Rotor Replacement Check rotor thickness, scoring, and pulsation before pad-only pricing. Estimate
Caliper Inspection Mechanics often inspect calipers when pad wear is uneven or the wheel shows drag after braking. Estimate

  • Use pad-only pricing only when rotors, calipers, and hardware pass inspection.
  • Quote pads and rotors when scoring, pulsation, rust lip, or thickness concerns are present.
  • Inspect seized caliper hardware, slide pins, rotor condition, and brake fluid condition before final approval.
  • Add caliper or brake-fluid service only when inspection supports it.
