How does a bias bar work?

A balance bar (also called a bias bar) on dual master cylinder systems, divides the force from the brake pedal to the two master cylinders. It is called a “balance bar” because that is exactly what it does. The torque on one side of the bar must balance the torque on the other side of the bar.

How do you adjust a Wilwood proportioning valve?

Connect the line going to the calipers to the “OUT” port. The adjusting knob is marked with an arrow indicating the direction required to decrease line pressure to the calipers. The knob rotated all the way out (counter-clockwise) will provide a maximum pressure reduction of 57%.

What does brake bias mean?

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.

What is a brake bias adjuster?

Remote Brake Bias adjusters from PitStopUSA.com are used with balance bars to adjust front-to-rear brake bias during changing race conditions. Remote Balance Bar Cable Adjusters fit most commonly used balance bars.

What is a balance bar car?

The balance bar is an adjustable lever (usually a threaded rod), that pivots on a spherical bearing and uses two separate master cylinders for the front and rear brakes. Most balance bars are part of a pedal assembly that also provides a mounting for the master cylinders.

Which way do you turn a proportioning valve?

Rotating the adjustment knob in a clockwise direction will allow more brake pressure to be applied to the rear brakes, counter-clockwise will reduce the pressure (when installed on the rear calipers line). At higher pressures, a piston separates the fluid at the inlet and outlet sides. No fluid flows through the valve.

How do you adjust a proportioning valve?

You’ll want to have around 60-70% of the braking on the front, so adjust the Valve clockwise to increase rear brake pressure and counterclockwise to reduce rear brake pressure. When the Valve is properly adjusted you should have even braking front and rear with neither one locking up before the other.

Does wilwood make brake boosters?

Next time you pop the hood of your car at the weekend cruisin, you can be proud showing off a truly classy and sophisticated power brake booster design with a name that can back it up. With this set up, the 9″ dual power brake booster combined with the Wilwood master will give you more than enough stopping power.

How does brake bias affect weight transfer?

Brake bias helps the driver maintain control while braking. When braking, weight transfers from the rear to the front. This increases traction in the front and reduces it in the rear. If the brakes had a 50/50 balance, the rear wheels would lock up first.

When should I adjust my brake balance?

In dry conditions, drivers want more brake pressure on the front of the car than the rear – usually a 60:40 or 55:45 split. As the weight, balance and tyre performance of the car changes during a race drivers adjust the brake balance to suit the handling.
