PC-BRAKE HYDRAULIC
is the only computer program commercially available that assists the brake engineer in designing the braking system for vehicles equipped with hydraulic brakes or allows the brake expert to analyze braking performance including brake failure of existing vehicles.

Starting with the basic vehicle information such as empty and laden weights, weight distribution, wheelbase and center-of-gravity height the engineer is guided to compare optimum braking forces with those produced by the hardware to be installed. The output is provided in terms of comprehensive tables and diagrams or charts. For example, the Braking Forces Diagram allows the engineer, or expert in case of an accident involving brakes, to immediately determine vehicle deceleration at ABS modulation or axle lockup for any tire-road friction coefficient and/or loading configuration.

The master cylinder size is optimized with respect to braking performance under booster failure conditions. The vacuum booster size is optimized based upon brake line pressure limits, pedal force considerations, and overall design parameters of the vehicle.

The brake fluid volume analysis allows the brake engineer to analyze the fluid volume requirements of each pressurized and non-pressurized fluid user in terms of actual braking effectiveness available for a given pedal force and pedal travel. Braking effectiveness with maximum brake pedal travel is analyzed.

Brake engineers as well as experts use the brake fluid volume analysis to investigate the mechanical condition of the brake system relative to partial brake failure. For example, excessive front wheel bearing play and its effect on front caliper wheel cylinder fluid requirements, and hence, loss of front braking (front-to-
rear-split) or one half braking

 

(diagonal split), can be analyzed in terms of pedalforce, braking effectiveness, and at what tire-road friction coefficient/deceleration the non-failed brake will lock and produce skid or ABS control marks.

Specific dimensions of brake pads, rotor and drum surfaces are optimized by the use of several specific design measures. Temperature limits and other parameters are established to ensure braking performance within established limits of braking temperature, fade and wear.

With major components of the braking system established, the engineer uses the parking section to design and ensure proper parking braking effectiveness under several operating conditions.

With all hardware components designed, the engineer establishes if any braking-in-a turn parameters require component adjustment to ensure acceptable braking effectiveness while turning.

PC-BRAKE HYDRAULIC includes the modules PC-BRAKE FACTOR (brake torque) for disc and various designs of leading-trailing, two-leading, and duo-servo brakes, and PC-BRAKE TEMPERATURE for single stop, repeated braking, and continued (down hill) braking.
