The Ford Lucas Girling brake system has long been recognized as a reliable braking technology used in various Ford vehicles, especially classic and vintage models. This article provides a comprehensive overview of the Lucas Girling brake system, common maintenance and repair challenges, practical service advice, and real-world experiences from Southern New Hampshire mechanics and enthusiasts. It aims to guide vehicle owners and technicians in preserving and restoring these classic brake systems.
Overview of Ford Lucas Girling Brake Systems
The Lucas Girling brake system combines components from two historic British manufacturers—Lucas and Girling—to create hydraulic brake assemblies characterized by drum or disc brakes, master cylinders, wheel cylinders, and associated hardware. These systems were prevalent in Ford cars from the mid-20th century through the 1980s.
Key features include:
Owners and mechanics often encounter several recurring issues with Lucas Girling brakes, including:
Step-by-Step Service Procedures
A Southern New Hampshire enthusiast embarked on restoring the brakes of a 1970s Ford Mustang equipped with Lucas Girling components. The vehicle suffered from a soft brake pedal and uneven stopping. Inspection revealed corroded brake lines, leaking wheel cylinders, and contaminated brake fluid. The restoration included flushing the system, replacing all brake lines with stainless steel braided hoses, rebuilding wheel cylinders with new seals, and fitting new brake pads and rotors. The end result was a responsive, safe braking system that preserved the vehicle's authenticity while enhancing performance.
Technical Glossary
Lucas Girling brake systems, while dated, remain popular among classic car restorers for their original equipment authenticity. Many restoration shops in New England, including Southern New Hampshire, specialize in servicing these brakes due to regional interest in vintage Ford models.
An anecdote from a local mechanic highlights the importance of patience and attention to detail: during a brake rebuild on a 1960s Ford Cortina, stubborn corrosion nearly prevented wheel cylinder removal. Specialized penetrating oils and gentle heat were employed to save the original hardware, preserving authenticity.
Summary
The Ford Lucas Girling brake system represents an important chapter in automotive braking history, especially for classic Ford vehicles. Understanding its components, common issues, and repair procedures enables owners and technicians to maintain these brakes safely and effectively. With thorough inspection, proper maintenance, and quality parts, Lucas Girling brakes can continue to provide reliable stopping power, preserving both safety and heritage for decades to come.
Overview of Ford Lucas Girling Brake Systems
The Lucas Girling brake system combines components from two historic British manufacturers—Lucas and Girling—to create hydraulic brake assemblies characterized by drum or disc brakes, master cylinders, wheel cylinders, and associated hardware. These systems were prevalent in Ford cars from the mid-20th century through the 1980s.
Key features include:
- Hydraulic Operation: Uses brake fluid to transmit pressure from the master cylinder to the brake shoes or pads.
- Drum and Disc Configurations: Early models often had drum brakes, later upgraded to front disc brakes.
- Manual and Power Assist Options: Some vehicles include power brake boosters to reduce pedal effort.
- Distinctive Components: Including master cylinders, wheel cylinders, calipers, and brake lines unique to the Lucas Girling design.
Owners and mechanics often encounter several recurring issues with Lucas Girling brakes, including:
- Brake Fluid Leaks: Due to aging seals in master and wheel cylinders.
- Corrosion and Rust: Particularly in brake lines and drums or discs, compromising performance.
- Worn Brake Shoes or Pads: Leading to decreased braking efficiency and noise.
- Sticking Calipers or Wheel Cylinders: Causing uneven braking or dragging.
- Air in Brake Lines: Resulting in spongy brake pedal feel.
- Difficulty Sourcing Replacement Parts: As many components are no longer produced in large volumes.
Step-by-Step Service Procedures
- Inspection: Visually examine brake components for leaks, rust, and wear.
- Fluid Check and Replacement: Test brake fluid for contamination and moisture; flush and replace as recommended.
- Brake Bleeding: Remove air from the system to ensure firm pedal response.
- Seal Replacement: Install new seals in master cylinders and wheel cylinders as needed.
- Component Replacement: Change worn shoes, pads, drums, discs, or calipers using compatible parts.
- Brake Line Assessment: Inspect for cracks or corrosion; replace lines if compromised.
- Adjustments: Set brake shoe clearance to manufacturer specifications for optimal performance.
- Use high-quality DOT 3 or DOT 4 brake fluid as specified for these systems.
- When replacing parts, seek OEM or quality aftermarket components designed for Lucas Girling systems.
- Regularly check brake pedal travel and firmness to detect early problems.
- Clean brake assemblies thoroughly before installation to prevent contamination.
- Avoid mixing brake fluids from different manufacturers to prevent chemical incompatibilities.
- Maintain a maintenance log to track brake service history and fluid changes.

Technical Glossary
- Master Cylinder: The component that generates hydraulic pressure when the brake pedal is pressed.
- Wheel Cylinder: Located in drum brakes, it pushes brake shoes outward to contact the drum.
- Caliper: In disc brakes, clamps pads onto the rotor to slow the vehicle.
- Brake Bleeding: The process of removing air bubbles from the brake fluid.
- Brake Fluid Contamination: Presence of moisture or debris in fluid that impairs braking.
- Brake Shoe: Friction material pressed against the drum to stop the wheel.
- Brake Pad: Friction material used in disc brakes.
