Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Conventional Brake System (Non-Hybrid Vehicles)
The brake pedal is connected to the vacuum power brake booster, which is connected to the brake master cylinder. When the brake pedal is applied, brake fluid is pushed through the double-walled steel tubes and flexible hoses to the disc brake calipers. The brake fluid enters the disc brake calipers, forcing the caliper pistons and brake pads outward against the brake disc friction surfaces, slowing or stopping wheel rotation. When the brake pedal is released, brake fluid pressure is relieved, returning the disc brake systems to the unapplied position.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
