Quick answer: Confirm front or rear position, caliper or brake package, pad outline and dimensions, wear-sensor provisions, hardware, production-date splits, and reliable part-number applications. Compare the old pad and caliper when the vehicle's history is uncertain.
Why year, make, and model may not be enough
Manufacturers can use multiple brake systems within one model year because of engine, trim, wheel size, performance package, production date, or supplier changes. Previous owners may also have installed larger brakes or donor components.
What to compare
- Front or rear axle position
- Caliper manufacturer/type and brake package
- Pad length, height, thickness, and outline
- Tabs, ears, clips, springs, and hardware
- Electronic or mechanical wear sensor provisions
- Rotor diameter or package identifier where applicable
- Production-date and trim exclusions
- OEM and manufacturer cross-reference numbers
If the brakes were changed
For a classic, modified, or repaired vehicle, identify the caliper and rotor actually installed. A brake conversion can make the donor application more useful than the chassis year. Record those details in the vehicle history so the next brake job does not restart the investigation.
Before ordering
Use manufacturer catalogs and dimensional drawings where available. Keep the old pads until the job is complete. Brake work is safety-critical: inspect the complete system and follow current service information rather than treating pad fit alone as proof that the repair is correct.
Save the brake setup that is actually on the car.
WrenchFit can keep brake-package, caliper, part-number, measurement, and modification notes with the vehicle for future research.
