Brake Bleed Lab
Plan brake bleeds, calculate fluid volumes, and generate step-by-step procedures.
An automotive service calculator that plans brake bleeds based on vehicle configuration. Computes fluid volumes, hydraulic ratios, and generates printable step-by-step procedures with safety warnings.
What It's Great For
Common scenarios where Brake Bleed Lab shines
Planning a full brake fluid flush
Technicians select vehicle specs, fluid type, and service scope to generate a complete flush plan with wheel order and volume requirements.
Diagnosing a spongy brake pedal
Walk through a structured decision tree to identify causes like incorrect bleed sequence, ABS air entry, or master cylinder bypass.
Upgrading brake fluid for track use
Compare DOT fluid specifications, check current fluid condition, and find a compatible high-performance replacement.
Preparing service documentation
Generate a printable checklist with step-by-step instructions, supply list, and torque specs to document completed brake work.
Calculating hydraulic leverage
Input master cylinder and caliper piston diameters to verify the hydraulic ratio is within safe bounds for a custom brake setup.
Features
What Brake Bleed Lab can do for you
