Wilwood Brake Products

 

Wilwood Engineering designs and manufactures high-performance disc brake systems. Since founding in 1977, Wilwood has developed a substantial matrix of brake components and engineering techniques that allow them to quickly and reliably create brake systems for almost any application. Wilwood's core ability is the rapid development of custom engineered brake systems using a combination of off-the-shelf and custom components. In addition to designing and manufacturing brakes for all types of competitive motor sports, Wilwood also manufactures brake systems and components for agricultural equipment, industrial applications, utility vehicles, snowmobiles, quads, motorcycles and military vehicles.

Wilwood employs approximately 250 people at their Camarillo, California facility. They have on-shelf stock of over 300 different brake calipers, 200 rotor designs, 100 master cylinder designs and a wide assortment of brackets, fittings, valves and brake lines. Wilwood's off-shelf brake calipers range in size from tiny calipers used on go-carts and light duty industrial equipment, to heavy duty original equipment brakes for the U.S. military Humvee. Wilwood's engineering department uses the latest computer aided design and manufacturing techniques in conjunction with finite element analysis, dynamic test and cycle test equipment, to find high-performance and reliability solutions to the most difficult braking tasks. Wilwood's extensive inventory of proprietary on-the-shelf components permit them to provide very cost-effective solutions to unique brake applications. Wilwood is ISO compliant and has extensive experience maintaining quality levels of 100ppm or less for original equipment manufacturers.

Brake Proportioning Valves & Pressure Valves

What is a proportioning valve?

A proportioning valve is a pressure reduction device used to adjust and tune brake bias. It is typically installed in-line in the rear brake line to reduce rear braking efficiency and compensate for premature rear-wheel lock-up; a result of incorrect front to rear brake bias. An adjustable proportioning valve permits incremental adjustments to fine tune brake bias. This ability to adjust front-rear brake bias is particularly important in race applications, as changing track conditions and vehicle dynamics usually require the brake bias be adjusted throughout the race.

 

What is brake bias?

Brake bias is the percentage of total braking force applied to the front wheels. It can also be called brake balance.  A 60-70% bias is common on RWD street vehicles, applying 60-70% of the total braking force to the front brakes. Front wheel drive cars can have up to 80% brake bias.
