The rear brake circuit is responsible for providing additional braking force and stability to the vehicle. It applies pressure to the rear brake calipers or drums to assist in stopping the vehicle.
The front brake circuit is usually connected to the master cylinder port labeled “Front” or “F”. This port supplies hydraulic pressure to the front brake system.	The rear brake circuit is usually connected to the master cylinder port labeled “Rear” or “R”. This port supplies hydraulic pressure to the rear brake system.
The front brake circuit may have additional components such as brake hoses, brake lines, and brake pads specifically designed to handle the higher braking forces.	The rear brake circuit may have components such as brake hoses, brake lines, and brake shoes designed to provide optimal braking performance for the rear wheels.

What Are the Front and Rear Brake Circuits?

The front and rear brake circuits in a vehicle are separate hydraulic systems that control the brakes on each set of wheels. The front brake circuit is responsible for applying pressure to the front brakes, while the rear brake circuit controls the rear brakes. This separation is crucial for multiple reasons.

First and foremost, it allows for independent control of the front and rear brakes, which significantly enhances the overall braking performance of the vehicle. During braking, the weight distribution of a vehicle shifts, with more weight transferring to the front wheels. By having separate brake circuits, the braking force can be appropriately distributed based on the weight distribution, resulting in more effective and well-balanced braking.

Moreover, the separation of the brake circuits provides redundancy and enhances safety. In the event that one brake circuit fails or develops a leak, the other circuit remains operational, enabling the driver to maintain some level of braking ability.
