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.

Rotor face and thickness are exposed during pad access.
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.

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
Commonly Bundled
Brake Caliper Inspection
Use when pad wear is uneven, the wheel drags, or slide movement is poor.
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
Rotor Inspection
Commonly checked with pad work when rotors are scored, warped, thin, or heat damaged.
Estimate
Situational
Measure pads and rotors
Confirm thickness, scoring, heat spots, and inner/outer wear.
Estimate
Check hub runout/play
Use when vibration or ABS evidence overlaps brake complaints.
Guide
Inspect caliper movement
Check slide pins, piston movement, hose restriction, and drag.
Guide
Caliper slide inspection
Slide condition affects pad wear and repeat comebacks.
- 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.
