I would like to convert my 1991 S10 to non power brakes. Would this or something else work?

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.

Hi I am from South Africa. Do you have a brake system that is floor mounted and not suspended as diagram?

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.

will it work on a 1962 nova??

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.

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?
Asked on 12/12/2011 1:27:26 PM by Thom from las vegas, nv
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.
