General guidance
Using the broadest public repair guide because no explicit vehicle was included in the query.
Vehicle Context Used
No year, make, model, or trim was included in the query, so this answer stays generic.
Overview
Confirm the exact axle before ordering parts because front and rear pad sets, sensors, and hardware often differ.
Brake jobs are safest when you inspect rotor condition, slide-pin movement, and fluid level before compressing the piston.
Year, trim, and parking-brake setup can change the tool list and piston retraction method.
Likely Causes
Pad friction material is at or below minimum thickness
Wear indicator squeal or grinding from metal-to-metal contact
Uneven pad wear caused by sticky caliper slides or seized hardware
Rotor scoring or heat spotting that should be corrected during the job
Tools Needed
Mechanic Cost
$220 to $650 per axle depending on rotor condition and labor rate
Related Vehicles
Most passenger cars and crossovers
Vehicles with electronic parking brakes may require a service mode
Performance trims with larger calipers may need specialty bits
Parts Needed
Brake pads matched to the exact year, trim, and axle
New hardware kit or shims
Rotors if they are below minimum thickness, cracked, or deeply scored
Brake fluid if the system needs a flush or the reservoir was contaminated
Safety Notes
Support the vehicle on stands and never rely on the jack alone.
Do not inhale brake dust; use brake cleaner and controlled wiping instead of dry blowing debris into the air.
Pump the brake pedal until it is firm before moving the vehicle.
Diagnosis Path
Step 1
Check pad thickness through the caliper window before tearing the car apart
Step 2
Inspect rotor surface condition and measure thickness if the rotor is close to its minimum spec
Step 3
Confirm the caliper slides move freely and the piston can retract smoothly
Step 4
Look for torn slide-pin boots, leaking calipers, or stuck parking-brake hardware on rear setups
How To Fix It
Fix 1
Secure the vehicle, remove the wheel, and support the caliper so the brake hose is never hanging under load
Fix 2
Remove the old pads and hardware, clean the bracket contact points, and lubricate the slide pins with the correct brake grease
Fix 3
Compress the caliper piston fully and install the new pads and hardware kit
Fix 4
Reassemble and torque all fasteners to spec, then pump the brake pedal before moving the vehicle
Fix 5
Perform the correct pad bedding procedure and recheck fluid level after the job
Stop And See A Mechanic
Stop 1
The caliper piston will not retract, the slide pins are seized, or the brake hose is damaged
Stop 2
You find fluid leaks, cracked rotors, or a soft pedal that does not recover after bleeding checks
Stop 3
The vehicle uses an electronic parking brake and you cannot put it into service mode safely
