1. What is Percentage Rear Braking?

Percentage Rear Braking is the proportion of braking force applied to the rear wheels in an independent suspension system to maintain vehicle stability and control. It ensures optimal weight transfer during braking for improved vehicle handling.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \%Br = \%ALr \div \left( \frac{SVSAh/SVSAl}{h/b} \right) \]

Where:

\( \%Br \) — Percentage Rear Braking (%)
\( \%ALr \) — Percentage Anti Lift (%)
\( SVSAh \) — Side View Swing Arm Height (m)
\( SVSAl \) — Side View Swing Arm Length (m)
\( h \) — Height of CG above Road (m)
\( b \) — Wheelbase of Vehicle (m)

Explanation: The formula calculates the proportion of braking force distributed to the rear wheels based on suspension geometry and vehicle parameters.

3. Importance of Percentage Rear Braking Calculation

Details: Accurate calculation of rear braking percentage is crucial for vehicle stability, preventing wheel lock-up, optimizing braking performance, and ensuring proper weight transfer during deceleration.

4. Using the Calculator

Tips: Enter all values in the specified units. Percentage Anti Lift, Side View Swing Arm Height, Side View Swing Arm Length, Height of CG above Road, and Wheelbase of Vehicle must be positive values greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: Why is Percentage Rear Braking important in vehicle design?
A: It ensures proper weight distribution during braking, preventing rear wheel lock-up and maintaining vehicle stability and control.

Q2: What is the typical range for Percentage Rear Braking?
A: The optimal value varies by vehicle type and design, but typically ranges between 20-40% for most passenger vehicles.

Q3: How does suspension geometry affect Percentage Rear Braking?
A: The Side View Swing Arm dimensions directly influence the anti-lift characteristics and thus the rear braking percentage calculation.

Q4: Can this calculation be used for all types of suspension systems?
A: This formula is specifically designed for independent suspension systems with swing arm geometry.

Q5: How does vehicle weight distribution affect the result?
A: The height of the center of gravity and wheelbase measurements account for the vehicle's weight distribution in the calculation.
