After DIY brake pad replacement, front brake caliper seizes and does not release, causing overheating, vibration, and smoking, with no clear cause found.

Workarounds Described

• uses C-clamp to force piston back manually for clearance

Implied Software Gaps

• Mobile diagnostic app that guides through load-dependent piston test and internal seal diagnosis

Brake Detective Pro

A mobile diagnostic app that guides DIY mechanics through symptom-based troubleshooting for brake issues. It uses a structured interview and step-by-step tests (including a 'bleeder open test' and load-dependent piston check) to pinpoint root causes like internal seal failure, even for rare cases. The app provides visual diagrams, torque specs, and repair videos, and logs history for future reference.
