The Process

How a guide gets built

🔍

You describe it

Tell us your vehicle and what's wrong — symptoms, sounds, error codes. The more specific, the sharper the guide.

🤖

AI cross-references

We pull YouTube repair transcripts, forum threads, and repair manuals to find the most reliable, commonly recommended fixes.

Step-by-step guide

Get an ordered guide with tools, parts, safety warnings, torque specs, and source citations — written for your exact vehicle.

Sourced from Real Mechanics

Trusted YouTube channels & forums — distilled.

Every guide is grounded in two pillars of grassroots automotive knowledge: hours of recorded repair videos and decades of forum wisdom from people who actually own your car.

Example Guide

Front Brake Pad Replacement — 2015 Honda Civic EX

Moderate⏱ 1.5 – 2 hours💰 $45 – $90 (parts)

⚠ Safety First

Always use jack stands — never rely on a hydraulic jack alone.
Brake dust is harmful — avoid inhaling it and wash hands after.
Bed in new pads gradually; avoid hard stops for the first 200 miles.

Tools

▶Floor jack

▶Jack stands (x2)

▶19mm lug socket

▶12mm & 14mm sockets

▶C-clamp or caliper piston tool

▶Torque wrench

▶Wire brush

Parts

▶Front brake pads (semi-metallic or ceramic)

▶Brake cleaner spray

▶Caliper grease packet

Loosen lug nuts on the ground

Crack each front lug nut a half-turn while the wheels are still on the ground. Much easier than fighting a spinning wheel.

Jack up & secure on stands

Place the floor jack under the manufacturer's jack point. Raise until the wheel clears, then set jack stands — never work under a car on just a jack.

Remove caliper & hang it

Remove the two caliper slide bolts (12mm). Slide the caliper off the rotor and hang it with a wire hook — never let it dangle by the brake hose.

Compress the caliper piston

Use a C-clamp or piston wind-back tool to push the piston back into the bore. Place an old pad against the piston as a buffer.

Install new pads & torque to spec

Slide new pads into the bracket. Reinstall the caliper and torque slide bolts to 25 ft-lbs. Reinstall wheel and torque lug nuts to 80 ft-lbs in a star pattern.
