New brake pads and rotors on a 2022 Dodge Challenger cause persistent high-pitched squeaking at low speeds despite multiple replacements and professional installation, with shops refusing further help.

No systematic diagnostic tool exists that can identify the root cause of brake noise (e.g., rotor/pad compatibility, hardware issues, bedding procedure failure) without trial-and-error part replacement.

Implied Software Gaps

Brake noise diagnostic app that uses sound analysis to pinpoint root cause

App Concept

BrakeNoise Analyzer

A mobile app that uses the phone's microphone to record brake noise patterns, then analyzes frequency and amplitude to diagnose the likely cause (e.g., pad material mismatch, glazing, rotor runout). It provides step-by-step troubleshooting procedures and recommends compatible parts, saving time and money on guesswork replacements.

Key Features

Record brake noise via smartphone microphone
Analyze frequency spectrum and compare to known fault signatures
Generate diagnostic report with likely causes and solutions
Integrated database of pad/rotor compatibility for common vehicles

Target Users: DIY car owners and independent auto repair shops working on passenger vehicles with brake noise issues

Revenue Model: Freemium with $9.99 per diagnostic report or $14.99/mo subscription for unlimited use + shop dashboard
