No there is not a return spring on this pedal assembly. You may want to add a return spring kit to each master cylinder such as 9402400 or add a spring to the pedal.

Is the Pedal height adjustable? I am thinking of putting this in a 53 Jeep, and am concerned that the pedal will not have enough travel. Can I adjust the resting position of the pedal so that instead of it being straight up and down, that the arm would angle towards the driver?

There is some slight adjustability but you can't get the pedal to a 45 degree angle or anything. Moving the pedal and inch or so forward and backward is very possible however.

Typically you would choose a bigger bore size for the front and a smaller bore size for the rear (1” bore to the front, 7/8” bore to the rear). The smaller bore size to the rear will give you more pressure to those brakes which will help set/turn the car when getting into the corners.

Pedal pressure compared to power brakes This unit has a different pedal ratio than power brakes which eliminates the need for a booster. What is the "feel" of this type of unit versus a power brake setup, more pedal pressure required, same as power brakes? My 63 Fairlane has Jag XJ6 front and rear independent suspension and a Ford 460 with no extra room on the firewall for a booster. Recently noticed the 90 degree swing pedal option for under dash mount of master cylinder and booster. Thanks!

This is one of racing's most popular pedals for Swing mounting two brake master cylinders with a bias balance bar. The pedal features all aluminum frame and arm construction with steel pivots, mounting studs, and an anti-skid pedal pad. Wilwood's clevis and pivot pin balance bar provide smooth and accurate settings of the brake pedal bias.

It will require a little more pedal pressure than a system with bost assist.

how many ounces do the reservoirs hold? and what bore would you recommend for 1/2 ton pickup with 4-wheel discs using 4 piston calipers in the front and single piston calipers in the rear?

Part number 91029975 These master cylinders hold 8.2 ounces of fluid and normally used on race or hot rod applications they are versatile for most any vehicle. The largest bore is 1” which would need to be used on the front 4 piston calipers and in the back you may want to use a 1” also but opting for a 7/8” bore would require less bias on the balance bar. You may want to visit with Wilwood tech service direct for other options.

This dual master cylinder stems from race applications but can be adapted to almost any vehicle or custom application. The master cylinders are normally mounted on the outside of the firewall and if needed, we offer a reinforcement plate that can be welded or bolted to the firewall. Length of pedal from pivot to bottom of pedal is 12” for fit verification. Another option to consider is reverse mount master cylinder kit under number 91029972.

This is a Wilwood swing pedal assembly and if needing a floor mount brake set up with similar configuration we suggest part number 91029976. This uses two master cylinders and similar dimensions as the swing mount.

This master cylinders and pedal assembly has a multitude of uses and on the newer vehicles to eliminate power brakes and gain some under hood space it works well. Builder would need to fabricate the appropriate under dash mount and we do offer a plate for the firewall if needed for additional support. For disc in front we would recommend a 1” bore master cylinder and for drum in the back you could opt for a 7/8” bore to limit the adjustment on the balance bar. You may want to plumb an adjustable proportioning valve into the rear line to fine tune the front to rear bias during hard braking. We also offer those under part number 91031353 as one example.
