![]() Continue alternating until you no longer see bubbles in the hoses.Pump the piston with a dowel, screwdriver, or the attached pushrod slowly through its entire stroke several times, then several short, fast strokes.Thread plastic fittings into the output ports, and route the hoses back to the reservoir.Try to get it level, or even with the front pointed down slightly, so air bubbles can escape through the compensating port or brake outputs.Clamp the master cylinder in a way that won't damage it, typically by the mounting flange.The only escape the bubbles have is back into the fluid reservoir through a tiny hole at the back of the bore, and most cars mount the master cylinder flat or at a slight upward angle, trapping air at the far end of the bore.īench bleeding is easy, but you will need a bench-mounted vice to hold the master cylinder. You will never have an appropriately firm pedal as long as there are still air bubbles that need to be compressed in front of the piston, and there is little chance they will find their way out on their own. It is crucial you bench bleed the master cylinder because, as mounted to the car, it is impossible to get all the air out of the piston bore. If you are installing a new master cylinder, Wilwood or OEM style, it is already out! But test fit it to the firewall/booster first and make sure everything is right, including the pushrod length, before putting fluid in it. ![]() Adjustable pedal stop eliminates stressing or stretching the throttle cable.The easiest part of bleeding the brake system is bench bleeding the master cylinder, though it requires taking it out of the car. ![]() Adjustable foot stop can be moved up, down, left or right to make your feet comfortable.Adjustable pedal pads can be moved up, down, left or right.Adjustable throttle pedal throw provides a quick or slow pedal feel.This adjustment is needed for different height/size drivers or for a young driver who is still growing. Adjustment of both pedals to be moved front or back as far as you need in minutes.The side style stem (which virtually all other micro sprint pedals are) can causing broken ankles in a hard-forward impact. Safety first as the center positioned pedal stem keeps the driver’s ankle from thrusting under the pedal plate.Our adjustable pedal assembly offers the following features: This provides more of the braking power to go to the front brakes. Use the small master cylinder to drive the front brakes. This provides another 1.45:1 ratio advantage for a total of 3.81:1 mechanical advantage. We recommend using one 5/8" master cylinder and one 3/4" master cylinder. A 100 pound force applied to the pedal can supply one master cylinder with 62 pounds of force and the other with 38. ![]() This means one master cylinder can get 2.63 times the force as the other. Our balance bar provides a maximum of 2.63:1 ratio advantage. The balance bar can be locked in place with the included jam nut, or used with an optional remote cable for quick on-track adjustments. A pin and clevis pushrod attachment system provides highest possible degree of misalignment angle for bind free operation through the entire range of travel. The balance bar incorporates a positive detent stop every full turn to maintain adjustment position and driver awareness. Some dirt track racers will like the adjustable brake bias as well. ![]() This is crucial for asphalt racing and works much better than a proportioning valve. The balance (bias) bar on the brake pedal allows adjustment to the amount of bias that each master cylinder has enabling more front or more rear brake bias. Upgrade your original Hyper Adjustable Pedal Assemblyĭual master cylinders allow one master cylinder for the front and one for the rear.
